    if ThrottleCmd < betarangeend/100.0 then engine power=idle, propeller pitch
    is controled by ThrottleCmd (between MINPITCH and  REVERSEPITCH).
    if ThrottleCmd > betarangeend/100.0 then engine power increases up to max reverse power
reversemaxpower [%]
    max engine power in reverse mode
maxpower    [HP]
psfc power specific fuel consumption [pph/HP] for N1=100%
n1idle_max_delay [-] time constant for N1 change
maxstartenginetime [sec]
    after this time the automatic starting cycle is interrupted when the engine
    doesn't start (0=automatic starting not present)

    (ielu = Integrated Electronic Limiter Unit)
