Under LOAs, who is responsible to comply when an aircraft is above LOA altitude and will enter an ATA?

• A. The Radar Controller at JAN and MLU Approach.
• B. The pilot.
• C. The FPL desk.
• D. The sector manager.

Answer: (A)

LOAs assign which controller is responsible for enforcing altitude restrictions and coordinating transitions between sectors or into an ATA. When an aircraft is operating above the LOA altitude and is about to enter an ATA, the responsibility for ensuring LOA compliance lies with the radar controller that covers the airspace involved—specifically the JAN and MLU Approach radar positions. These controllers monitor the aircraft’s altitude relative to the LOA requirement, issue or maintain the necessary altitude instructions, and coordinate the handoff into the ATA as needed. The pilot remains obligated to follow ATC instructions, but the formal responsibility for LOA compliance in that airspace lies with the controlling radar unit. The other options don’t carry this specific operational responsibility: the FPL desk handles flight plan data, and the sector manager oversees staffing and operations rather than enforcing LOA altitude compliance in real time.
