What does the collective control do?

• A. Elevators and Stabilizers
• B. Collective
• C. Cyclic
• D. Ailerons

Answer: (B)

Collective control changes the pitch angle of all rotor blades at the same time, which changes the total lift produced by the rotor system. Raising the collective increases blade pitch, producing more lift and causing the aircraft to climb; lowering it decreases lift, causing descent. This control sets altitude rather than direction, unlike cyclic (which tilts the rotor disc to move horizontally) or the control surfaces used on fixed-wing aircraft (elevators and stabilizers, ailerons).
