EC135 Nav Display TTG / A.ALT

  • Hi,

    I've got two problems with EC135.

    First, when I select an ALT to acquire via A. ALT, climbing stops approximately 100ft / 150ft below the desired altitude and stay there. Is it normal ?

    Secondly, I must admit I have a comprehension problem with the TTG indicator in NMS mode. In VOR mode, the TTG indicates the time to go in minutes, and that's ok.

    But in NMS mode, TTG indicates a number that can't be minutes or even HMM.

    Ex: TTG:795 for a 60 NM trip ! How to interpret this number ?

    Many thanks for those who can help.

    B.

  • Hi Jan,

    1 - For TTG, you said: "it was not calculated", do I have to understand that it 's going to be updated in a future version ?

    2 - For altitude acquisition, I was always in initial climb, straight to desired level.

    Don't know if it is linked too, but when I select a rate of climb to the desired altitude, with the trim cap, the true rate (V/S white bar) is always under the selected V/S (triangle)

    Ex: must select 700 ft/mn to obtain 550 ft/mn

    Thanks Jan

  • Thanks Jan, TTG is now coherent in NMS. Will perform other tests with autopilot altitude mode, because it was pretty accurate yesterday, but encountered bugs like 2000ft/mn rate of climb with A.ALT what led me to... zero airspeed. Perhaps xwas my fault, don't know at this time.

    Ah, and just to say it: LSK of the FMC are inoperative (EC135): we must paste frequencies and active them only with the right keys.

    Again thanks for such reactivity.
