What is the acceleration of a Chinook helicopter?

The acceleration of a Boeing-Vertol CH-47 Chinook helicopter is typically expressed as the rate of change in its velocity over time. It can vary depending on several factors, including the helicopter's weight, altitude, airspeed, and atmospheric conditions.

As an example, the CH-47D Chinook can have a maximum acceleration of approximately 17.6 feet per second squared (ft/s^2) or 5.36 meters per second squared (m/s^2). This acceleration rate refers to the maximum achievable change in the helicopter's velocity in a given direction.

However, it's worth noting that the helicopter's acceleration is usually significantly lower during normal operations. It typically accelerates gradually to maintain a steady climb rate or to transition between different flight modes.

It's important to consult with specific flight manuals or performance specifications for the CH-47D Chinook or any other helicopter model to determine their exact acceleration capabilities and limitations.
