What is the drop speed range of a CH-47?

The correct choice identifies the drop speed range of a CH-47 as 80-110 knots. This range is vital for ensuring the safety and effectiveness of personnel drops from the aircraft. The CH-47 Chinook, as a heavy-lift helicopter used by military forces, is designed to operate within specific speed parameters during drop operations, which allows parachutists to exit the aircraft smoothly and safely.

When executing a drop, the speed must be sufficiently high to maintain stability and control of the helicopter while ensuring that jumpers have the appropriate airtime for deployment of parachutes. Operating within the specified speed range maximizes the opportunity for successful parachute deployment and helps minimize risks associated with wind conditions and turbulence that can affect drop accuracy.
