Changelog

Version 2.2.0

• Money reads properly. Every figure is grouped in thousands — $46,150.00 rather than $46150.00 — on screen, in reports and on every printed document. Negative amounts show as -$3,400.00 instead of $-3,400.00.
• The same figures whoever prints them. The grouping is fixed to the US format rather than following your computer’s regional settings, so an invoice does not print 46.150,00 on a machine set to another country.
• Automatic capitals made consistent. Fields marked to keep what you type now do so in every case — the manual search box was being capitalised despite being marked otherwise. Licence keys, email addresses, web addresses and letter text are left exactly as typed; a licence key is case-sensitive and capitalising one would stop it activating.
• One rule across all three apps, so GA MX Helper, GA Wire Helper and GA Build Helper cannot drift apart on this again.

Version 2.1.0

• Print the whole job package. On any work order, one PDF holding every document tied to that job — the quote it started as, the work order, the traveler sheet, the invoice, any purchase orders raised against it, any parts returned under it, and the logbook entries written from it. One print for the folder instead of seven.
• A cover sheet lists what’s inside and the page each document starts on, so a folder copy can be checked at a glance.
• Only that job’s paperwork. Documents are gathered by the link in your records, never by date or tail number, so two jobs a week apart on the same aeroplane stay separate.
• Tick what you want before it builds. Anything the job hasn’t got yet is listed but can’t be ticked, so the window doubles as an inventory of the job.

Version 2.0.1

• The payment method on an invoice comes from your own list. Settings → Accounting Info → Payment Methods already held the ways your shop takes money. Everything on it is now offered in the method dropdown when you record a payment against an invoice, alongside the built-in Cash, Check, Credit Card and PayPal — which are always there whether or not you’ve set anything up.
• A payment method no longer needs a link or a QR code. Add ACH, a wire transfer, a shop account or a trade by name alone. It’s offered as a method and simply doesn’t appear in the QR-code list on an invoice, because there’s nothing to scan for it. Give an entry a link or a QR picture and it prints on the invoice as before.
• Removing a method doesn’t change anything already recorded. An invoice you were paid on by Venmo still shows and prints Venmo after you remove it, and reopening that payment still offers it. Taking a method off the list stops it being offered in future, nothing more.

Version 2.0.0

Everything since 1.87 in one release. An aviation converter, shop-wide find, a records self-check, a quick reference library, adverse-load and ballast checks, an employee time clock, proper employee records with pay history — and a UI refresh that lets most of the app be read as blocks instead of rows. Per-version detail is below.

• New: every equipment check prints as a logbook entry, including sticker sizes. Each record on the Equipment Checks & Placards tab now has a Logbook entry button beside its full-sheet print.
  • The same sizes as the app’s own logbook entries — full page, half page, 4"x6" and 3"x5" index cards, and the four label sheets: Avery 5163 and 8163 (2"x4"), Avery 5168 (3.5"x5") and OnlineLabels OL1252WX (4"x7", Legal). Label sizes let you pick the start position, so a part-used sheet isn’t wasted.
  • The wording is written for you from the record and names the paragraph the work was done under. A VOR entry carries the date, place and bearing error that 91.171(d) asks you to enter. It’s editable before it prints, with a button to put the generated wording back.
  • It will not say an aircraft complies when the record doesn’t show it, and it will not carry a next-due date on a check that didn’t pass. It doesn’t sign anything — you get a signature line, exactly like a logbook entry.
  • A pitot-static entry can carry the readings — scale error at each test altitude against its tolerance, the Table II results, friction, barometric scale error and the altitude reporting points, each marked within or OUT. It’s an option, not a requirement: appendix E (d) asks only for the date and maximum altitude tested, both already in the entry.
  • Or save it straight to Log Items, where it becomes an ordinary log entry you can sign, edit and batch-print like any other. Saving again updates that entry rather than adding a second one.
• New: an Equipment Checks & Placards tab on every aircraft, gathering the recurring equipment checks and the cards and placards that go with them, under a currency strip worked out from the records rather than typed in.
  • Temporary placards have moved out of the Flight Data Add-On into the base app, where they belong — a placard is ordinary maintenance work, and so is a compass swing. Flight Checklists and Performance Data stay in the add-on.
  • ADS-B Out performance report against the figures in 91.227(c)(1) and (d), which is where most Non-Performing Emitter letters come from. 91.227 sets no re-test interval, so nothing is called due unless you set a review date of your own.
  • VOR accuracy checks — the 30-day check in 91.171, with the tolerance picked from the method: ±4° for a VOT, repair-station signal or surface checkpoint, ±6° for an airborne checkpoint or airway-radial ground point, 4° between the two sets on a dual cross-check.
  • ELT — the 12-calendar-month inspection in 91.207(d) and the battery date from 91.207(c). Navigation databases — which cycle is in what, and when it expires.
  • The currency strip doesn’t pretend these are the same kind of problem. An out-of-date ELT stops the flight; an out-of-date altimeter system test only stops IFR.
• The pitot-static editor is five steps instead of one long form — it was four screens of scrolling for one record, and the first step now fits on one screen. Each step carries a count of what’s left on it, red where a reading is outside a published tolerance.
• Fixed: several settings in these editors couldn’t actually be changed. The transponder class, the altimeter type, the “what was tested” boxes, the ELT’s 406 MHz box and the VOR check method all snapped back the moment you set them. The class decides which appendix F limits apply and the VOR method decides whether the tolerance is 4° or 6°, so this one mattered.
• New: pitot-static and transponder test records, on a new Pitot-Static tab in every aircraft file. Record the 24-month altimeter system and transponder test, and print the report.
  • The format isn’t ours. Shops lay these sheets out differently, but what goes on them is fixed by 14 CFR part 43 appendix E for the altimeter system and appendix F for the transponder — static system, scale error, hysteresis, after effect, friction, case leak, barometric scale error, altitude reporting correspondence, and every appendix F item from (a) to (j).
  • Every tolerance is the regulation’s own figure, printed beside the box you type into, with the verdict appearing as you go.
  • Due dates are calendar months. 91.411 and 91.413 say “within the preceding 24 calendar months”, so a test on 14 March 2026 is good through 31 March 2028 — not the anniversary of the test. One press puts that date on the aircraft’s scheduled maintenance.
  • A failed test is recorded as found, with what was out of tolerance and the paragraph that says so. A test point you didn’t run stays blank — never an error of zero — and a sheet with gaps reads as incomplete, not as a pass.
  • It won’t invent a tolerance for an altitude appendix E doesn’t publish one for, and won’t judge an air data computer altimeter against tables that appendix E (b)(2) says need not apply to it.
  • Also new in Quick Reference Data: Pitot-Static Tolerances — all four appendix E tables, the appendix F limits, who may do the work, and a due-date box.
• New: compass correction cards, on the aircraft’s Placards tab. Record a compass swing and print the card that goes beside the compass.
  • The layout is the FAA’s own: twelve headings with a STEER figure for radios on and off, from AC 43.13-2C Table 3-1. So is the limit — “maximum acceptable deviation in level flight is 10 degrees on any heading” (paragraph 3.4.6).
  • Deviation is worked out as you type, for both radio states. Over 10° turns red on screen and prints red on the card with the paragraph quoted.
  • An over-limit swing still saves — it asks first. A swing that failed is the one most worth having written down.
  • A blank box stays blank. A heading nobody swung prints as a dash with a line saying so, never as a 0° deviation.
  • Every swing is kept, the older card marked superseded rather than overwritten.
• Card views across the app. Parts, tools, work orders, quotes, sales orders, invoices, purchase orders, part returns, customers and suppliers can each be shown as cards or as a list, with a switch above the list and the choice remembered per list.
• Job time is now recorded against whoever is signed in, not against the name on the installation. The labour clock on a discrepancy used to stamp the name from Settings — the owner’s — no matter who was at the terminal, and so did the technician offered on a new logbook entry, on AD compliance, on a weight and balance revision and on a work order sign-off. On a shared shop machine that put the wrong name on records that go on paperwork.
  • Nothing already signed is touched. An entry made by somebody who has since left still shows their name and their certificate — this changes what’s offered for new work, not what’s on the record.
  • An employee with no certificate number on file gets a blank one, never the owner’s.
• They start as lists, exactly as they always have — nothing moves under you. Only the aircraft registry leads with cards.
• Parts show quantity against minimum, expiry, cost and on-hand value, with below-minimum and expired called out. Tools show the photograph, calibration state and jobs used on. Work orders show squawks open against total, parts, labour hours and dates. Invoices show total, balance and status. Customers show aircraft, open jobs and what they owe. Suppliers show open POs and contacts.
• No money figure on a work order card, on purpose: an invoice has one authoritative total, a work order doesn’t, and inventing one here would eventually disagree with the invoice.
• Search, sort and the filter chips drive both views the same way.

Version 1.99.0

• The Aircraft tab is now a grid of cards, two across, instead of a table of rows. A row tells you what an aircraft is; a block tells you what it needs, without opening the file.
  • Registration and status across the top, with the card’s left edge coloured to match — you can pick the AOG aircraft out of a full screen without reading a word.
  • Boxes for open discrepancies, maintenance due, ADs, and engine readings where you’re using engine analysis. Red for overdue or AOG, amber for due soon, green for clear. Hover any box for the detail.
  • Make, model and series, serial number, year, home airport. Hobbs, tach and cycles side by side, plus airframe total time where it’s recorded.
  • The single most urgent thing outstanding, by name and figure. How many records are being kept, and when the last entry was made.
• Registration expiry is surfaced when it’s lapsed or inside sixty days — a date that grounds an aircraft and that nobody is watching.
• The engine box only appears on aircraft you’re actually monitoring. One with no engine data gets no box rather than a green zero: “nothing unusual” and “nobody is looking” are different statements.
• The table hasn’t gone anywhere. A Cards / List toggle sits next to Add Aircraft and the choice is remembered — the table is still faster for scanning forty tail numbers. Search, sort and the status chips drive both.

Version 1.98.0

• Employees have proper records now. Employee number, hire date, employment type, status (Active / On leave / Inactive / Former), who they report to, and an emergency contact. The list shows status and how long each person has been with you, and former employees are greyed rather than hidden — their records still matter.
• Pay, kept as a history rather than a single figure. You record a pay change with the date it takes effect, and the old rate stays on the record for the weeks it was in force for. Hourly or salary, with an overtime-exempt tick, and a future effective date is allowed. A rate stored as one number rewrites the past every time it changes — cost a week from March with today’s rate and the figure is wrong, confidently and invisibly. A yearly figure typed into the hourly box gets queried rather than quietly costed.
• Pay has its own permission. Without it the whole Pay section is hidden, the rate column is blank, and pay entries are kept out of the history too — and it tells you how many are hidden rather than pretending there are none. On a shared shop terminal, everyone’s rate visible to anyone who opens Settings is a real problem.
• History with the company — a dated log: hired, role changes, training, certifications, reviews, commendations, leave, departures. Role changes, status changes, departures and pay changes write themselves in, so it’s a record of what happened rather than of what somebody remembered to type. At the top, how long they’ve been with you — measured to their last day if they’ve left.
• Gross labour cost on the time clock. With the Pay permission, each person’s block in Settings → Time Clock gains a cost for the range with the overtime split shown. Threshold and multiplier are yours to set — 40 hours and ×1.5 to start with.
  • It is not payroll, and it says so. Gross only — no deductions, no taxes, no net pay.
  • Hours on days with no rate on file are left out and reported, not costed at whatever rate happens to be nearest.
  • Overtime is a weekly decision, so a range that cuts a week in half is costed at straight time and flagged. A week that’s simply still running is reported differently — that one settles itself on Sunday.
  • Salaried people aren’t costed from punches. Their hours still show; the cost doesn’t move with them.

Version 1.97.0

• New: an employee time clock. A Time Clock tile on the Status page, under Active Employee. It names whoever is currently selected, says whether they’re in, and counts up while they are. One button — Punch In, then Punch Out — and once they’re out it shows their total for the day. It punches the active employee, and switching who that is already needs their four-digit PIN, so nobody punches in as someone else.
• Settings → Time Clock is the history: filter by person and date, or use Today / This week / Last week / Last 14 days / Everything. Per-person totals in hours and minutes and again in decimal hours, which is the form payroll usually wants, and an Excel export. Alongside each total, the hours booked to jobs over the same range, so you can see time worked but not booked.
• Nothing closes a shift for you. A forgotten punch-out stays open, gets flagged on the tile and at the top of the history, and is left out of the totals. An app that invents a knock-off time is worse than one that shows you the gap.
• Overlapping punches are called out — two punches for the same person covering the same hours put those hours in the total twice, and it’s nearly always a correction typed into the wrong row.
• A new Time Clock permission, set per person under Employees & Permissions. Corrections need it, or Administrator; everyone else sees the history with no Edit or Void buttons at all. A one-person shop with no employee records set up isn’t restricted.
• Every correction keeps its reason. Changing a punch asks why, and stores what it was, who changed it and when. Deleting is a void: the row stays, struck through and out of the totals, and can be restored. A payroll record that can vanish without trace isn’t a record.
• A shift crossing midnight is counted on the day it started, as one shift. And this is all separate from the labour clock on a discrepancy, which records billable time against a job — attendance and billable time answer different questions.

Version 1.96.0

• The Hardware reference is now Quick Reference Data. On the menu it reads Quick Ref; Alt + H still opens it from anywhere, and nothing has been taken out — it simply covers more than hardware now.
• New: Cables & Turnbuckles. Type a cable diameter and get the turnbuckle safetying guide for that size — single or double wrap, safety wire diameter, material. At 1/8 inch three combinations are permitted and it shows all three, because the published guide does not rank them. A size the guide does not reach is told so rather than rounded to the nearest row. With the 7 × 7 and 7 × 19 constructions drawn in cross-section, and the three-threads-exposed rule.
• New: Fluid Lines. The flared fitting table, by tube outside diameter or by dash size — 1/4 and -4 both work. Fitting nut torque for aluminium tubing and for steel, the hose end fitting range, and the minimum bend radius for both. Where the published figure is blank you get a dash, not an invented number. Plus the rule people get wrong: flareless fittings are not torqued to that table — bottom the nut, then one flat on the hex.
• New: Dissimilar Metals. Pick two metals and it tells you which one corrodes and how far apart they sit in the galvanic series. It stops there on purpose — position tells you which metal goes, not that a pair is fine without a separator. With the aluminium groupings, because two aluminium alloys can be dissimilar metals, and the primer and tape rules for protecting a joint.
• New: Mounting Loads. For putting a box in an aircraft: enter the weight of the equipment and it works out the static test load in each direction, for normal/utility, acrobatic, items of mass in the cabin and rotorcraft. With the three-second hold, the 1.5 factor of safety, and the list to work through before you sign — two retaining devices per removable fastener, weight and balance recorded, placards into the ICA limitations.
• Sources for the new panels: AC 43.13-2C, issued 29 July 2026, which cancels AC 43.13-2B, and FAA-H-8083-30B Chapters 7, 8 and 9. As always, each panel names the table or figure it came from, and nothing comes from a vendor catalogue.

Version 1.95.0

• The Hardware reference now has pictures. Head markings, nuts, washers and rivet heads side by side, and on Safetying a cotter pin through a castle nut and a double-twist safety wire showing which way the wire has to pull.
• New: Check a joint. Put in the material thickness, the bolt grip and the washer stack — and the nut height and bolt length if you want the thread protrusion checked — and it draws the joint to scale and tells you whether it is right: grip against the material, washers against the 1/8 inch limit, and whether a thread stands proud of the nut.
• Find has moved into the company box at the top left, under your name, in orange — rather than sixteenth in the menu. Ctrl/Cmd + K still opens it.

Version 1.94.0

• New: adverse-load CG checks and ballast sizing, on the aircraft’s Weight & Balance tab. After a repair or alteration you have to show that no legal loading puts the CG outside limits — this works the forward, aft and maximum-weight cases from your own station list and tells you whether each one passes.
• Ballast sizing when the empty-weight CG is outside a limit: enter the station the ballast would go on and it tells you how much, shows the arithmetic, and warns if that station is on the wrong side of the limit to help.
• It uses the FAA Weight & Balance Handbook’s own figures — nominal 170 lb occupants, minimum fuel as METO horsepower ÷ 2.
• It will not guess. If a seat row doesn’t say how many seats it has, or baggage has no maximum, it tells you what to fill in and computes nothing. A guessed seat count would make an aft check pass when it should fail.

Version 1.93.0

• The Hardware reference now decodes part numbers. Type AN3DD5A or AN4-6A and it takes the number apart — diameter, material, length, whether the shank is drilled, whether the head is drilled for safetying. Solid rivets too (MS20470AD4-5), and the common AN nuts and washers.
• It points out something that catches people: the figure in a bolt part number is the length, not the grip. Shop habit often says grip, and they aren’t the same thing — grip is the thickness of material the bolt actually holds.
• Everything comes from the FAA’s AMT Handbook — General, Chapter 7, and the panel says so.
• Fixed: the “estimated” marker in the torque table now sits only on the shear figure, which is where the FAA’s asterisk applies. Three tension figures were wrongly labelled as estimates.

Version 1.92.0 — with GA Wire Helper 1.2.1

• New: a Hardware reference. On the menu, or Alt + H from anywhere. It shows aircraft hardware and the published figures that go with it — it doesn’t pick hardware for you, and it isn’t approved data.
• Torque — the full AC 43.13-1B Table 7-1, both thread series, tension and shear nuts, in inch-pounds. Type a thread size to find it; 3/8 shows both the fine and the coarse thread. Where your maintenance manual gives a torque for the job, that one wins — the reference says so.
• Through an adapter… on every row hands the figure to the Converter, so you can work out what to set the wrench to through a crowfoot without re-typing anything.
• Identifying a bolt — what the head markings mean, and which nut goes with which bolt. A bolt with no marking at all is low strength.
• Grip & threads and Safetying — grip length and the 1/8 inch washer limit, one thread through the nut, never reusing a cotter pin, and bringing a castle nut up from minimum torque rather than past maximum to find the hole.
• Every figure is taken from AC 43.13-1B Chapter 7 as the FAA publishes it, and each panel names the table it came from so you can check it.
• GA Wire Helper 1.2.1: a live demo on this website, and the sample wiring project now carries a revision history so the revision sheet shows what it does.

Version 1.91.0 — with GA Wire Helper 1.2.0

• New in GA Wire Helper: a Converter, on the toolbar and on Alt + C — the same one GA MX Helper got in 1.90.0, so both apps give the same answer. Units, fuel and fluid weights, decimal hours, torque through an adapter, drill sizes and Ohm’s law. No internet needed.
• New in GA Wire Helper: Crimp tooling in the AC 43.13-1B reference. Pick a wire size and it tells you which M22520 tool class covers it, what it is used for, and how to check the tool is still in calibration. It deliberately does not name positioners or dies — those belong to the contact you are crimping, so it points you at the contact manufacturer’s data instead of guessing.
• New in GA Wire Helper: Revision history. The title block has always had a revision letter; now there is a dated record of what changed at each one and who changed it, and it prints as its own sheet.
• New in both: the parts list crosses over. In GA Wire Helper, Send to GA MX Helper on the Parts List. In GA MX Helper, open the aircraft, go to Wiring, and the diagram offers Add parts to a squawk. Components come with quantities and reference designators; wire comes by the foot, and any run with no length recorded is called out rather than quietly counted as zero. Everything arrives as Needed — nothing is taken from stock and nothing is ordered.

Version 1.92.0

Released alongside 1.2.1 (GA Wire Helper)

• New: a Hardware reference in GA MX Helper. On the menu, or Alt + H from anywhere. It shows aircraft hardware and the published figures that go with it — it doesn’t pick hardware for you, and it isn’t approved data.
  • Torque — the full AC 43.13-1B Table 7-1, both thread series, tension and shear nuts, in inch-pounds. Type a thread size to find it; typing 3/8 shows both the fine and the coarse thread, which is the distinction that matters when you’re holding the bolt. Where your maintenance manual gives a torque for the job, that one wins — the reference says so.
  • Through an adapter… on every row hands the figure to the Converter, so you can work out what to set the wrench to through a crowfoot without re-typing anything.
  • Identifying a bolt — what the head markings mean, and which nut goes with which bolt. A bolt with no marking at all is low strength.
  • Grip & threads — grip length, the 1/8 inch limit on a washer stack, one thread through the nut, and why you measure the old bolt instead of trusting the parts manual.
  • Safetying — what must be locked, never reusing a cotter pin, and bringing a castle nut up from minimum torque rather than past maximum to find the hole.
  • Every figure is taken from AC 43.13-1B Chapter 7 as the FAA publishes it, and each panel names the table it came from so you can check it.
• New: GA Wire Helper has a live demo on the website. The real app with a sample wiring project, nothing to download and nothing to sign up for. Draw and change whatever you like; nothing is saved, and documents open as pictures rather than printing.
• The sample wiring project now has a short revision history in it, so the revision sheet shows what it does rather than printing blank.

Version 1.91.0

Released alongside 1.2.0 (GA Wire Helper)

• New: Find — one box for the whole shop. Ctrl/Cmd + K, or Find on the menu. It searches parts, tools, aircraft, work orders, quotes, invoices, sales and purchase orders, returns, squawks, customers, suppliers, documents and people all at once, grouped by kind with the closest match first. You no longer need to know which tab a record lives in before you can look for it. Scanning works exactly as before — the app tells a scanner from a person by how fast the characters arrive.
• New: Check My Records. On the Reports tab, one button runs 13 checks across the whole shop: work orders open too long, closed jobs with parts but no invoice, squawks closed with no corrective action, the same serial on two records, stock below minimum with nothing on order, tools past calibration, recurring ADs with no next-due date, shelf-life parts past their date, aircraft with no logbook entry since their last job, serial counts that disagree, records pointing at something deleted, parts replaced while still under warranty, and cores gone more than 60 days. Every finding opens the record it found, and the report prints. It is the pass you would otherwise do on paper before an audit.
• New: it tells you when an inspection is actually due. "Due at 3022.3 hours" depends entirely on how much the aircraft flies, so the app now works that out from the readings you have already logged and shows a date — on the aircraft page, in the Status due-soon list and on the Calendar. It will not guess where it shouldn’t: a calendar item is already a date, cycles are not flying hours, and with only a reading or two to go on it says the figure is rough. A projection is always labelled as one and never written in as a due date.
• New: photos on a squawk. Before and after, from a file or straight from the camera, each with a caption. They print on the work order and can go on the invoice — which is where they settle an argument about what was actually wrong.
• New: warranty on the parts you fit. Each part records when it went on and how long it’s covered. Fit the same part to the same aircraft again while the one it replaced was still in its term and the app tells you then and there, in time to claim rather than after the invoice has gone. The term comes from your shop default, the part, or the line on the job — and zero months means no warranty rather than "use the default".
• New: it notices when two computers share one folder. If the data file changed on disk since you opened it, you get a banner saying so and three choices: keep yours, take theirs, or save yours separately. Saving stops until you decide, instead of quietly writing over someone else’s work. Your work stays on screen throughout.
• New: Kits. A named set of parts you use together — an annual kit, a 100-hour kit, a hose change — put on a job in one action instead of eight lines by hand. The kit shows what’s short and, separately, what isn’t in inventory at all. Short lines go on the job as On Order without touching stock rather than being dropped. One button turns the shortages into a purchase order, and there’s a pick sheet to print.
• New: the Owner Status Page. Owners ask where their aircraft is. One button writes a single file you can email them: times, what’s due next, what’s open, what was recently done. It opens on any phone or computer, needs no internet and nothing installed, and it’s read-only. It carries no labour rates, no hours, no part costs, no currency figures at all, no supplier names and no other aircraft. Preview it before you send it.
• New in GA Wire Helper: a Converter, on the toolbar and on Alt + C — the same one GA MX Helper got in 1.90.0, so both apps give the same answer. Units, fuel and fluid weights, decimal hours, torque through an adapter, drill sizes and Ohm’s law. No internet needed.
• New in GA Wire Helper: Crimp tooling in the AC 43.13-1B reference. Pick a wire size and it tells you which M22520 tool class covers it, what it’s used for, and how to check the tool is still in calibration. It deliberately doesn’t name positioners or dies — those belong to the contact you’re crimping, and it points you at the contact manufacturer’s data instead of guessing.
• New in GA Wire Helper: Revision history. The title block has always had a revision letter; now there’s a dated record of what changed at each one and who changed it, and it prints as its own sheet. The revision letter in the title block keeps itself in step.
• New in both: the parts list crosses over. In GA Wire Helper, Send to GA MX Helper on the Parts List. In GA MX Helper, open the aircraft, go to Wiring, and the diagram offers Add parts to a squawk — tick what you want and it lands on the job. Components come with quantities and the reference designators they came from; wire comes by the foot, and any run with no length recorded is called out rather than quietly counted as zero. Everything arrives as Needed: nothing is taken from stock and nothing is ordered.

Version 1.90.0

• New: a Converter, included with every license. It’s on the menu on the left, and Alt + C opens it from anywhere without leaving what you were doing. Like the rest of the app, it needs no internet.
• Units — length, weight, volume, pressure, torque, speed, area, power, angle and temperature. Type a figure into any box and every other box fills in; there’s no convert button and no direction to pick.
• Fuel & fluids — gallons or litres into pounds or kilograms and back, for a weight and balance or a fuel load. Avgas, Jet A, oil and water are set to the FAA Weight & Balance Handbook’s nominal weights, and you can type the actual figure off the fuel ticket over any of them, since fuel changes weight with temperature.
• Decimal hours — tach and Hobbs readings into hours and minutes and back, plus the difference between two readings. 1.7 hours is 1 h 42 m, not 1:40.
• Torque through an adapter — what to set the wrench to when a crowfoot moves the socket away from the head.
• Drill sizes — number, letter and fractional drills in one chart. Type #30, F, 3/16, 0.159 or 4.5 mm and get the decimal and metric size, any other name for the same hole, and the nearest sizes either side.
• Ohm’s law — any two of volts, amps, ohms and watts give you the other two.
• Density altitude, wind and fuel planning are flight calculations and stay where they are, in the Flight Data Add-On under Go Flying.
• The release notes inside the app were missing versions 1.88.1 and 1.89.0. Both are there now.

Version 1.89.0

• The app now works with no internet connection. Printing used to need one without saying so: with no wifi, every PDF quietly failed — work orders, logbook entries, 337s, tags, labels — and so did Excel export and CSV import. Everything the app does is now built into the file, so it all works in a hangar. The only things that still reach out are the ones genuinely about the outside world: activating your license the first time, weather, and looking up recent ADs.
• Backups now keep a file per day instead of one file written over and over. The old backup protected you against losing the folder, and against nothing else — delete something by mistake and the next backup copied the mistake over your only good copy within the hour. Now each day gets its own dated file, so yesterday is still there tomorrow. The last 14 days are kept by default; choose 7, 30, 90 days or a year. The newest copy is still written under the usual name, and nothing else in that folder is ever touched.
• A backup that fails now tells you — what went wrong, when, and a button to try again — instead of failing silently. The app also says how many days of backups you have on disk and how much space they use.
• Your backup schedule, airport-database token and other settings belonging to this computer no longer get lost once your records outgrow what a browser will hold.

Version 1.88.1

• Fixed: the app asked for your license key every time you opened it. This only affected installs whose records had grown past what a browser will hold on its own — which is most shops after a while, and exactly when the folder on your disk becomes the real copy of your data. Your activation was being stored inside that browser copy, so when the app cleared it (which it does on purpose, rather than open to a stale snapshot of your records), the activation went with it. Activation is now kept separately, where the size of your data can’t disturb it. You should not be asked again.

Version 1.88.0

• New: Part Returns / Repairs — what used to be called Core Returns. A repair is a round trip, so it now tracks both shipping legs, out to the vendor and back again, each with its own date, carrier, tracking number and freight cost, and each with its own live tracking link. The repair sheet totals the freight for the whole trip.
• The return's status now sits at the top of the screen with a colour-coded badge and a plain-language note telling you where the part actually is — out to the vendor, repaired and waiting, on its way back, in the shop, or back on the shelf.
• New: put a repaired part back in stock with one button once it returns. Quantity for ordinary stock, the returned serial number for a serialized part. If the vendor sent back a different unit there is a separate field for the serial that came back, and the app uses it from then on. A return can only be restocked once.
• New: print a Part Condition Tag or Part Label straight from a return, without re-typing the part. The tag knows which direction the part is going — Unserviceable / As Removed with your reason on the way out, Serviceable / Repaired with the vendor's reported condition on the way back.
• Renamed, so it is clear what each label is for: Storage Location Label (was Inventory Tag) for a bin or shelf; Part Condition Tag (was Condition Tag) for a serialized, repairable or transferable part; Part Label (was Stock Serviceability Label) for disposable, one-time-use stock.
• The Storage Location Label now belongs to the location, not the part. It prints the bin in large type with everything kept there listed under it, and a QR code that pulls up that bin's contents when scanned. Print one bin or every bin at once.
• New: usage, ordering and cost history on every part — a chart and a list built from your own work orders and purchase orders, with nothing extra to enter. How many you have used and bought by month, what you have paid per unit over time, and an arrow showing which way the price has moved since the first purchase on file. Each figure names the work order or purchase order behind it.
• New: tools can carry a photo, the same as parts — on the tool's own screen and as a thumbnail in the tooling list.
• Three decimal places on unit prices and rates, for hardware bought by the thousand at fractions of a cent. The third decimal only shows when it matters.
• Fixed: part details entered while printing a label — storage location, lot number, expiration date — are now saved back to the part, and a corrected Total Time or TSO on a condition tag is kept. Quantity is deliberately left alone, since the number on a bag is not your stock level.
• Fixed: the return/repair sheet printed a blank first page and ran onto a third. It now fits on one page, with each shipping leg on a single line and the QR code tucked into the top corner.
• Fixed: the returns list on a supplier's profile showed uncoloured status badges.
• Fixed: the dashboard's open-returns count missed several statuses.
• Add-on features are now marked with a ✦ throughout the app, and Settings → License lays out exactly what your installation includes and what it does not.

Version 1.87.0

• New: Wiring Diagrams tab on each aircraft profile, for use with the new companion app GA Wire Helper. It lists every wiring diagram and PDF made for that aircraft, and "+ New Wiring Diagram" opens GA Wire Helper with the aircraft already filled in. The tab only appears once GA Wire Helper is linked.
• New: V-Speeds — an editable V-speed grid per aircraft, printed automatically in the Flight Checklist booklet (Flight Data Add-On).
• New: Airport Frequency Directory — CTAF, ATIS, Approach and any other frequencies per airport, shown on the aircraft overview for the home airport and printed in the checklist booklet's Airport Info box (Flight Data Add-On).
• New: Go Flying E6B-style calculator with density altitude and one-tap home-airport selection (Flight Data Add-On).
• Performance Data tables now include bar and line charts, on screen and in the printed PDF (Flight Data Add-On).
• The Go Flying dispatch sheet and checklist supplement now print together as one combined document, with post-flight times just above the signature block.
• Flight Checklist boxes (Weight & Balance, V-Speeds, Airport Info) now size themselves to fit their content.
• Fixed: Engine, Propeller and Accessory log entries now show and print the aircraft's registration, make, model and serial number together with the component's own make, model, serial number, Total Time, Time Since Install and Time Since Overhaul. Twin-engine aircraft let you pick which engine or prop.
• Fixed: log entry printouts now use the same layout at every size — full page, half page, index cards and every label sheet — scaled to fit.
• Fixed: Flight Checklist text could run past the bottom of its box. Boxes with a lot of content now flow into side-by-side columns so everything fits at a readable size.
• License activation now checks that a key belongs to GA MX Helper, and bundle keys unlock every add-on they include.

Version 1.85.0

• Importing the FAA's Airworthiness Directive database for AD cross-referencing (Settings → Data Storage) is now much easier: the file FAA's DRS gives you can be imported directly, with no conversion step required first.
• The AD Search results list now has "Add Selected" and "Add All" buttons, so a large batch of matching ADs can be added to an aircraft in one step instead of one at a time.
• New: Flight Checklists — a printable, pilot-facing checklist booklet built from an aircraft's procedures, plus a revision history log and an automatically generated Weight & Balance quick-reference box (part of the Flight Data Add-On).
• New: Placard categories — tag each placard (Fuel, Electrical, Emergency, etc.) and filter by category in a growing placard library.
• New: Performance Data — quick-reference tables for cruise, climb, glide, stall speed, and takeoff/landing distance figures straight from your aircraft's POH/AFM, with their own printable reference sheet (part of the Flight Data Add-On).
• Small consistency and wording improvements throughout the app.

Version 1.84.0
