Plane in a vertical loop and gravity

    1. The problem statement, all variables and given/known data
    A plane makes a vertical loop like in the drawing. the speed is exactly what is needed that at the highest point the pilot wont feel any force nor from the seat and nor from the safety belts.
    1) what is the weight of the pilot in comparison to the airplane?
    2) what gravity feeling has the pilot?

    2. Relevant equations
    Acceleration in circular motion: ##a_r=\frac{V^2}{R}##

    3. The attempt at a solution
    1) the pilot's weight can be anything, even very heavy in comparison to the plane, i don't understand the question.
    2) the pilot feels only g, so he is in free fall, like astronauts. but what does he feel? nothing? when i fall i feel sick

    So what is the question I can help with ? Because I agree with you on both counts, I feel pretty helpless in helping out...:smile:

    Do they mean the weight of the pilot/aircraft on the ground or the apparent weight or both at the top of the loop?
