Common aircraft properties

WORK IN PROGRESS

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 aircraft properties (if not alias them).
