When ever I start from a cold & dark Plane I cannot get the Auto Throttle Arm switch to ARM. I've been following the tutorial listed on the PMDG website! I'm not getting any warning alarms on my takeoff run so the plane must be configured correctly. I don't have this problem when I start the simulation with the Bird running hot!Any ideas?Pete

Pete: The other times this has been reported here, the problem was that the engine generators were not on. The engine generators are necessary for a/t to arm.sj MantelKEWR
