  • This is QID 320119.
    The correct (given) answer is 465m.
    The graph output is 1500 ft. The answer required is in metres.
    3.28 ft = 1m
    1500/3.28 = 457m.

    The closest answer is 465m, which means that the examiner's graph output was 1525 ft. We are close enough to the...

    Hi Kat
    If I follow you correctly you draw a line across the CG envelope (fig 4.13) at the given mass and then draw a line from the index to intersect it. Is that correct?
    With your numbers I get over 21% MAC....

    Hi Kat
    The result is not a lot different.
    The exact gradient can be found by using the formula Gradient = roc/Tas x 6000/6080
    The Roc can be found in the graph which is 980 fpm
    Gradient = 980/111 x 6000/6080 = 8.71% (rounded to 8.7)

    Still air distance = 1450/8.7...

    replied to Asking for an exam review
    You can appeal it on the grounds that there were more than 4 multi path graph questions.
    The review cost is the same as the exam fee and would be refunded if your appeal is successful.

  • The question is asking for the volumetric capacity of the tanks. Nothing to do with the mass which can only change with the SG.
    I can assure you that the given answer is the one required by the examiner....

  • To correct the pitch down moment a pitch up input is made to the elevator/stabiliser, the vertical load on the tailplane will increase downwards. (Also referred to as trim drag)

  • Thanks Moss
    I will be challenging the CAA on this as ops makes no reference to light aircraft.

  • Hi Moss
    Thanks for the feedback it is very much appreciated.

    I'm mystified by your remark that in a 'light' aircraft the pilot is part of the traffic load. I can't find any reference for that so if you have one please let me know.
    Thanks.

    replied to V1 decrease with mass?
    V1 is defined as the minimum speed to accept the engine failure and continue the take-off and make V2 and 35ft within TODA and also the maximum speed to reject the take-off and stop within ASDA. The variables of TODA and ASDA clearly influence the permitted maximum take off mass. You therefore can increase...
