Ok i try it once more.
I tried to use the autothrottle now with diferent addon models from wilco.
The Wilco 737, 777, Embraer and Airbus.
And the autothrust does only work with the B777 as i expect it to work.
I expect the autothrottle to work like if i engage it and leave the lever alone i am able to manage the speed via the panel. Except at the B777 from Wilco, and of course the FSX standard aircraft, it doesnt work. The autopilot still gives to much power into the engines. the thrust lever is in TOGA position i enable autopilot/autothrust to climb in managed mode but the autopilot doesnt reduce to climb power. an in level flight for example if i level off at 5000 feet with a speed in autopilot of 250 Kts IAS, although autothrottle engaged the aircraft goes beyond maximum speed because the thrust is not reduced by the autothrottle.
I dont know so far where the problem is, and as i said with standard aircraft and for wichever reason with the Wilco B777 it works well.
With the Wilco airbus i want the autothrottle wo work like if i put the levers backwards the autothrottle reduces the Mode to climb power, and that from now on the autopilot is managing the speed.
looking forward for your help with programming that
