    Engine and FDM have changed : reduce idle thrust and drag at Mach 2.0.

    Because above 50200 ft, VMO is always (1) in Mach number
    (MMO = Mach 2.04) : max climb mode.

    While the initial calibration flight had a cruise speed around
    Mach 1.98 = 530 kt, which could depend of temperature and pressure.

    Cruising at Mach 2.02, I runned out of fuel.

    Now, since the cruise speed is constant (Mach 2.02), it is easier to
    foresee the consumption (which however decreases with climb).

    Reducing the idle thrust enables the deceleration at Mach 2.02.

    (1) Except if air is too hot, where the speed is reduced to stay
    below 128°C (max cruise mode).  A goal for the next patch.
