If you are asked to 'report leaving the airspace boundary', what should you do?

• A. Report your position to ATC on the current frequency.
• B. Continue on current instructions.
• C. Remain silent.
• D. Report leaving the designated sector boundary.

Answer: (D)

Crossing from one controlled airspace into another requires ATC to know when you leave the current sector. When you’re told to report leaving the airspace boundary, you must notify ATC as you cross, indicating that you are exiting the boundary. This helps ATC reassign you to the next controller and maintain safe separation. Include your position, altitude, and time in the report as appropriate. This fulfills the controller’s request and keeps air traffic informed. Remaining silent or continuing without making that boundary report would leave ATC unaware of your exit, and a general position report on the same frequency would not satisfy the explicit instruction to report the boundary crossing.
