ai aircraft makemdl.parts question

[this4dave2]

Hi


I am working on an ai aircraft and i was wondering if it is possible to have a part animate or disappear at a given time and not appear again until the aircraft lands and shuts down using XML code to do it. If any body can help with an answer and the xml code that will do this i would appreciate it.

I tried to use external or tip tanks fuel depletion as a trigger to no avail it appears that ai aircraft never runs out of fuel so the external or tip tanks never become empty is it true or am i missing something.

If any body has an ideas how to make external or tip tanks to deplete it fuel with XML code so i can use it as a trigger it would be appreciated.

Thanks for your help
David

This allows you to delay the visibility time.
When the Jets NAV light works but only if you configured in the aircraft.cfg two engines.
