Explain the functions of the control surfaces and flight controls for a rotary-winged aircraft.

Explanation should include 

  • pitch and roll—controlled by the cyclic control tilting the main rotor 
  • yaw—controlled by the foot pedals of the anti-torque system that changes the blade pitch in the tail of the aircraft 
  • collective—allows the rotor blades to change pitch simultaneously to increase or decrease lift  (to increase or decrease altitude).

Process/Skill Questions: 

  • How is pitch and roll controlled on a rotary wing aircraft? 
  • How is yaw controlled on a rotary wing aircraft? 
  • What is the purpose of a collective?
