The problem is the question is badly flawed. In
trimmed level flight, the advancing blade is doing none of those things, because the cyclic controls have angled the swashplate (because there is a pilot somewhere around) to make the blade produce roughly the same forces (lift) and moments (control) as it advances or retreats.
In an uncontrolled helicopter rotor, the advancing blade gets increased speed (the sum of forward spoeed and rotational speed) and it has an increase in lift and drag. This makes it rise, and peak at the full forward position. The handy-dandy pilot forsees this because he pushes the cyclic forward as the nose starts up (the nose up is a product of the blade rising and the disk tilting backward).
In Canada, there is no pilot, and the blade flaps uncontrolled, causing the helo to crash, of course.
The correct answer is (z) Why ask a government flight examiner to write a test on aerodynamics when we have Dave Jackson?
