    Hi all,

    I got problems to get the turbine in the C208 analog running.
    located somewhere in Iran with inside temperatures of about 70°C I'm not able to start the turbine.

    I tried any possible switch position and combination with external Power switch, Starter Switch, Ignition....
    Double checked fuses...
    Helpless at the moment

    Sorry you've having trouble. Does the aircraft start in cooler climates? I don't believe there is anything in the Caravan that should preclude a start in warmer temperatures. My only other thought is a hardware control binding that's interfering with fuel flow.

    Please send me a video, if you can, that would be immensely helpful in diagnosing the problem.

    @Black-Square
    Thank you for the reply.
    I changed weather condition, so the temperature was reduced to about 20°C. Engine wont restart.
    To solve this i reloaded the plane. I dont't think I can reproduce the failure. But I keep an eye on.

    Isn't the Fuel Boost pump supposed to be on prior to start and the low fuel pressure light out?

    I've been flying the Caravan a lot in Africa and so far have had no problems starting.
