What is the maximum airspeed of the CH-47D helicopter?

The correct answer, indicating the maximum airspeed of the CH-47D helicopter is 170 knots, reflects the specifications and performance capabilities of this specific aircraft model. The CH-47D, a twin-engine, tandem rotor helicopter, is primarily used for troop transport, cargo lift, and logistical support in various military operations.

The 170 knots figure represents the optimal balance of speed and performance for this helicopter, which is designed to operate efficiently in various environments and situations. Factors such as weight, altitude, and external conditions can influence actual flight performance, but the stated maximum airspeed remains a key figure in understanding the operational limits of the CH-47D.

Understanding this maximum airspeed is crucial for mission planning and execution, ensuring that pilots and crew can utilize the helicopter to its full capabilities while maintaining safety and effectiveness in tactical situations. Other options listed do not align with the certified performance data for the CH-47D, as they exceed the operational limits established during testing and evaluation phases.
