collective pitch control
- Definição1
- The control for changing the pitch of all the rotor blades in the main rotor system equally and simultaneously and, consequently the amount of lift or thrust being generated.

- Nota Adicional1
- The collective pitch control, located on the left side of the pilot’s seat, changes the pitch angle of all main rotor blades simultaneously, or collectively, as the name implies. As the collective pitch control is raised, there is a simultaneous and equal increase in pitch angle of all main rotor blades; as it is lowered, there is a simul- taneous and equal decrease in pitch angle. This is done through a series of mechanical linkages and the amount of movement in the collective lever determines the amount of blade pitch change.
- Nota Adicional2
- Raising the collective pitch control increases the pitch angle the same amount on all blades.
- Contexto
- There are four basic controls used during flight. They are the collective pitch control, the throttle, the cyclic pitch control, and the antitorque pedals.
