Aircraft profiles

What is in an aircraft’s settings file. One JSON file per aircraft, in the aircraft folder next to Aerotto.exe. Aerotto picks the file whose TitleMatches words appear in the sim’s aircraft title. Everything optional is off unless the file sets it.

The structure

{
  "Name": "Cessna 408 SkyCourier",          // identity
  "TitleMatches": ["C408", "SkyCourier"],  // words in the sim's aircraft title that pick this file

The parts

Part	Required	What it holds
Identity	yes	Name, title words, fuel type, tested flag, minimum app version
Speeds, attitudes, flaps	yes	The numbers Aerotto flies the circuit with
Optional tuning	no	Cruise, control gains, flare, safety nets, water settings; each off by default
Autopilot	no	How to drive the aircraft’s own autopilot en route
Ground	no	Power-up, start, pushback, taxi and shutdown
WalkAround	no	Which covers and chocks to take off and how
Lights	no	The aircraft’s own light switches

How profiles change

• One aircraft at a time. What is learned on one aircraft goes into its file. Every optional setting defaults to the value all aircraft were flight-tested with, so a setting added to one file changes that aircraft alone.
• Versioned. MinAppVersion is the first release that understands every key in the file. The profile bundle on aerotto.com updates installed copies between releases; an app older than that number keeps the file it was installed with.
• Tested or not. FlightTested turns true once the aircraft has flown its tests; until then the app says so and the supported aircraft table shows it as in testing.
• Made one for a new aircraft? Tell us on Discord. Pilot-made profiles ship with the maker’s name in the app.
