I think that explains properties which reset themselves... As for the engines running on thin air - I don't know. I know I've run out of fuel before with the Lightning and I'm sure the engines stopped. I know the "fuel and payload" menu is greyed out with JSBSim a/c (because JSBSim doesn't yet support changing these values on the fly AFAIK - I could be wrong). > 2. i've tried to set the cutoff property to true, but the engine kept > running and the property was set back to false. what went wrong? I found the best documentation for the engine startup and shutdown procedures to be in src/FDM/JSBSim/models/propulsion/FGTurbine.h I just tried and setting controls/engines/engine/cutoff[0] to true (on the 737-300) does stop the first engine as expected. (It also stops _all_ engine noise by the way, if someone is looking for another way to improve the 737 :-) HTH, AJ ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
