FSX has many Simulation Variables (SimVars), unfortunately only a limited selection are exposed for use by the mission engine.

Others can be exposed through 3rd party tools, (e.g. FSXME SimVar.exe).

When utilising an SimVar in a mission,
you should ensure it is available in your target FSX version.

Important

Condition triggers are tested multiple times per second.

Having lots of concurrently active condition triggers
may have a performance impact affecting subsequent actions.
i.e. an action or trigger might not fire.

Only activate condition triggers when nescessary.
Always deactivate condition triggers after use.
