  • Ah, yes, but then it involves an action from the pilot.
    My problem is, i read the question like : if A happens while the plane is flying straight, while I should be reading : when pilot is maintaining straight flight.
    Thanks for the answer !

    Question ID: 811268

    Question states that for an aircraft flying straight and level at constant IAS, when flaps are extended the induced drag stays the same.

    I fail to imagine a situation where a plane can keep the same lift value, flight level and IAS before and after extending the flaps, how is it possible...

  • Hi,
    In the picture of the bobweight, it seems clear that, a dive would pull the stick, inducing a nose up moment; and a climb would induce a nose down moment.
    So it could pull the stick backward and forward; why is the answer A right ?

    I see, it is all about maintaining IAS.
    I understood how increasing blade pitch of a windmilling prop reduces drag.
    But I have a problem with the wording of the question.
    the question states that the event happens at a constant IAS, but not that the pilot apply the relevant corrections....

    Hello,
    question states that During a glide with idle power and constant IAS, if the RPM lever of a constant speed propeller is pushed full forward from its normal cruise position, the propeller pitch will decreases to increase the negative angle of attack.But this increased angle of attack increases...

    Question states that If the propeller pitch of a windmilling propeller is increased during a glide at constant IAS the propeller drag in the direction of flight will decrease and the rate of descent will also decrease.
    I always considers drag to act as a kind of brake and slow down the plane....

    Question 811000 states that The difference between a propeller's blade angle and its angle of attack is called helix angle.
    So If I am not mistaken, if we consider a stationary aircraft, blade angle equals angle of attack and helix angle equals 0, is that correct ?
