When should you request the position of an aircraft during emergency assistance?

Requesting the position of an aircraft during emergency assistance is crucial for providing accurate and timely support, especially if the aircraft is not displayed on radar. In scenarios where the aircraft's location is unknown for any reason, such as equipment failure or communication issues, it is vital to gather as much information as possible from the pilot. If the pilot has not communicated their current position and there is no radar data available, requesting this information becomes necessary to ensure that appropriate assistance can be provided.

This allows air traffic controllers to determine the aircraft’s trajectory, altitude, and potential risks, thereby facilitating a proper response to the emergency situation. Gathering the aircraft's position assists in coordinating search and rescue efforts, if needed, and ensuring the safety of the flight crew and passengers. The focus on requesting this information when it is not displayed on radar highlights the importance of communication and data exchange in emergency management.
