Property Tree/Reference
From wiki.flightgear.org
| Property Tree |
|---|
There will never be a full reference to the property tree, as each different aircraft will present data in a different structure.
However, below are some of the typical data structures you might encounter.
- Controls - are generally considered to be "in" to control the sim,
- Flight Dynamics Model - is the sim calculation and generally read only; can be manipulated.

Flight Controls
The basic flight controls. Properties such as speed brakes do not exist on a cessna.

Reading the values of the controls is at

Engines
Engines are numbered engine[0] for a single engine to engine[0] to engine[3] for a 747 for example. (The model allows for up to 12 engines rumour has it ;-)

Position
This will return the current position of the aircraft within the sim. This is also the stuff thats transmitted in multi player.
