Hi, I am having a problem with arming the auto throttle on the above aircraft. I am trying to get to grips with F2Crew but so far have only managed to get to the runway only to find that when I go to ARM the auto throttle it will work sometimes; and othertimes it wont stay ARMed. Can any one suggest what I may be doing wrong? The FMC seems to be setup ok but could the A/T be affected by the Load Manager or Fuel setup?

Hello Peter,Make sure both engine generators are on-line. You need to bring them on-line during your After Start flow. Basically all you're doing is changing the electrical power source from the APU to the Engine.Cheers,Bryan
