A helicopter is hovering and the pilot applies right pedal. Assuming the main rotor rotates anti clockwise viewed from above, the helicopter will
- descend, unless the pilot applies more collective pitch.
- descend, unless the pilot inches the throttle open.
- ascend, unless the pilot decreases rotor RPM.

Shouldn't "C. ascend, unless the pilot decreases rotor RPM" be the correct answer?
This is because due to torque, the fuselage tends to yaw right.
Applying right pedal means you wish to yaw right, by decreasing the anti torque required (reducing thrust by tail rotor), so less power is needed by the tail rotor, more power available to the main rotor, helicopter ascends

Strictly speaking, the marked answer is incorrect. Correct is "ascend, unless the pilot decreases rotor RPM", because with an anticlockwise rotor the right pedal reduces tail rotor pitch, so the tail rotor absorbs less power and, with the throttle unchanged, rotor RPM and main rotor thrust increase.
