The power control on the end of the collective control is called what?

• A. Twist Grip
• B. Throttle
• C. Pedals
• D. Cyclic Stick

Answer: (A)

The twist grip is the power control at the end of the collective. In many light helicopters with a piston engine, engine power is adjusted with a throttle device located right at the end of the collective grip. This lets you change engine RPM and overall power without taking your hand off the collective, which is essential for maintaining rotor speed (NR) during hover, takeoffs, and transitions. As you increase or decrease power with the twist grip, you help keep rotor RPM within the proper range to avoid over- or under-torque conditions. The other controls—cyclic for flight path, pedals for yaw, and the collective for pitch/lift—do not adjust engine power, which is why this end-of-collective control is specifically identified as the twist grip.
