TODO: standardise locations most common to existing aircraft to ease transition
With common aircraft properties found in uncommon locations, assigning buttons in joysticks to certain functions became mostly a hit or miss affair.
There was an attempt to unify it all with a nasal script but after consulation and comments with others, this attempt was replaced with the solution to standardise common aircraft properties in standardised locations.
This document will exhaustively list property tree locations where aircraft developers should store their common aircraft properties (if not alias them).
Gear
Properties marked with an '✲' are standard across all aircraft and should always be set. For example, an old aircraft without any autobrakes should still define /controls/gear/autobrake although set it to 0
