Which trio are the three main controls of a helicopter RPA?

• A. Ailerons
• B. Cyclic, Collective, and AntiTorque Pedals
• C. Elevators and Stabilizers
• D. NOTAMs

Answer: (B)

In rotorcraft, the three primary flight controls are the cyclic, collective, and anti-torque pedals. The cyclic tilts the rotor disk to steer the aircraft in the desired direction—pushing the control forward moves you ahead, left or right to change direction. The collective changes the pitch of all rotor blades together, which increases or decreases lift and lets you climb or descend. The anti-torque pedals control the tail rotor’s thrust to counter the main rotor’s torque and to yaw the helicopter, letting you rotate left or right. Ailerons and elevators are designed for fixed-wing aircraft, not helicopters, so they aren’t the three main controls here. NOTAMs are notices about airspace or other conditions, not control inputs.
