  • Down.
    An aircraft pitches around its CG. If the CP is behind the CG, the moment it creates will be constantly trying to pitch the nose down. A downforce must be created at the tailplane to stop the nose dropping, and hold the aircraft in level flight.

    There's no disrepancy.
    I've advised you previously to take note of EVERY word in the question. It asks what will happen in the NEXT HOUR.
    The image shows point "A" to be on the cold front NOW. The text says there will be a brief, slight drop in pressure as the front passes....

    Congratulations on the pass, and thanks for the very comprehensive feedback.
    Interesting.....plenty of the most recently-written questions are in there, but plenty of the old originals from way back are still appearing, as well.
    Good luck with the next move in your career!

    You're right, torque is perpendicular to the propellor axis.
    The plane of rotation is also perpendicular to the propellor axis. Think of it as the path that the propellor blades follow when it is rotating, (assuming the propellor isn't moving)
    Torque is therefore parallel with the plane...

    The answer's right, the explanation's confusing. I'll improve it.
    The last paragraph adds some extra information about freezing rain. What's missing is a statement that 12000ft is the right answer because we are above both freezing levels, and therefore the probability of freezing rain is reduced...

    Are you a BGS student? If so refer to ATPdigital Met lesson 19 pages 9 and 10. We also discuss this confusing area on the brush up course at Clevedon.
    At the top of page 9 it states "Warm occlusions will have the shape at the surface of a warm front".
    In this question, the image...

    Check the wording of this question. It says "What is the MOST LIKELY cloudbase..........."
    The definition of a "Tempo" is a set of conditions that will be present for less than half the period defined. Therefore it is most likely that, when you arrive at the airfield, the tempo...

  • Until recently, all these questions were like 811316. You found the answer using a simple ratio, as shown in the explanation. (NOTE : You suggest we've used the formula New Vs = Vs x √LF, but we haven't in this one). The gust has produced only a modest "bump" of 1.3 g, while the speed...

    This old, badly-worded exam question doesn't include a diagram. Instead, the writer has tried,(without much success) to describe in words the situation in the photo you've provided here.
    In your image, the straight line is the warm front and the curved line is the cold front. The cold front no...

    This is a controversial question. Our problem with answer c is that we would expect the windshear at the top of the inversion, not the bottom. This makes answer d the only one that's correct, but it's somewhat unsatisfactory because the loss of engine performance in the last few hundred feet of the...
