When you expect an enroute descent, what is a key fact about the controller's authority?

• A. The controller may terminate the descent at any time
• B. The controller cannot terminate it without pilot consent
• C. The pilot must always request a descent
• D. The controller can only terminate in poor weather conditions

Answer: (B)

The key fact about the controller's authority during an enroute descent is that the controller may terminate the descent at any time. This reflects the principle that air traffic control holds ultimate responsibility for ensuring safe separation and traffic management within the airspace. In practice, when a controller issues a clearance for descent, they retain the authority to modify that clearance based on traffic requirements, weather conditions, or other safety considerations. This means that just because a pilot is cleared to descend does not guarantee that the descent cannot be stopped; the controller may intervene as necessary to maintain safety. Understanding the dynamics of this controller-pilot relationship is crucial for safe operations during descents. Pilots should remain vigilant and prepared to respond to any changes in instructions from air traffic control, ensuring that they comply with directives for a safe flight.
