What should a pilot do when faced with a situation that allows no response to flight controls?

In a situation where a pilot faces an inability to respond to flight controls, declaring an emergency is the most critical and appropriate action to take. This decision is vital because it communicates to air traffic control and other relevant authorities that the aircraft is experiencing a serious issue that requires immediate attention and assistance.

When an emergency is declared, it allows for priority handling by air traffic control, enabling the pilot to receive necessary guidance and support, such as priority landing clearances, vectors to the nearest airport, or any other assistance that may be needed to ensure the safety of the aircraft and its occupants. It also prompts the crew to focus on the critical situation at hand, ensuring that they are in the best position to resolve the emergency or prepare for a safe landing.

In contrast, simply engaging the autopilot might not resolve the underlying issue, especially if the controls are unresponsive, and could lead to a deteriorating situation. Considering it a normal flight would be highly inappropriate and dangerous, as it dismisses the severity of the problem. Requesting a vector to the nearest airport could be part of the response, but declaring an emergency should come first to afford the necessary prioritization and assistance.
