What should a pilot do if they receive a clearance limit?

When a pilot receives a clearance limit, the key action to take is to leave the clearance limit according to the expected further clearance time (EFC). This means that the pilot should wait for the EFC provided by air traffic control, which indicates when they can expect further clearance to continue on their route. Until the EFC is reached, the pilot should maintain appropriate altitude and position as indicated in the clearance limit, ensuring they comply with any restrictions during this time.

This approach helps maintain safety and orderly flow of air traffic. Following EFC gives pilots the necessary structure to manage their flight while waiting for further instructions. It is important for pilots to stay within the limits of ATC instructions, as departing from the clearance limit prematurely can lead to conflicts with other air traffic and could potentially place the aircraft in a hazardous situation.

Maintaining the clearance limit altitude is crucial as it aligns with air traffic control's expectations, ensuring the aircraft is positioned safely. This helps avoid altitude deviations that could lead to unsafe situations in busy airspace.
