Quick Summary

Collective pitch control is a lever in helicopters that changes the pitch angle of all main rotor blades simultaneously. Moving the lever up increases the pitch angle, which increases lift and drag, causing rotor and engine RPM to decrease. Conversely, moving the lever down decreases the pitch angle, reducing lift and drag, and increasing RPM. This control is linked to the throttle to automatically adjust engine power, making it the primary control for both altitude and power.1
