¶ Introduction
The collective pitch control (or "collective") is located on the left side of the pilot's seat:
The main function of the collective is to raise or lower the helicopter through various mechanisms that have an effect on the main rotor
¶ Use of the Collective Pitch Control
The collective can be raised or lowered vertically, usually with the pilot's left hand:
The primary effect of moving the collective will be a change in height
- When the pilot raises the collective: there is an equal increase in the pitch angle of all the main rotor blades → the angle of incidence increases → helicopter climbs
- When the pilot lowers the collective: there is an equal decrease in the pitch angle of all main rotor blades → the angle of incidence decreases → helicopter descends
