Under what condition can you cross the Maneuvering Area Delimitation (MAD) line?

The condition allowing you to cross the Maneuvering Area Delimitation (MAD) line is when you have a valid D-AVOP and explicit permission from Air Traffic Control (ATC). This requirement ensures that only trained personnel who understand the protocols and regulations related to airside operations are authorized to enter critical areas where aircraft are maneuvering.

Receiving ATC permission is crucial for safety, as it helps prevent any potential conflicts with aircraft that may be operating in the vicinity. The D-AVOP certification indicates that the operator is knowledgeable about the rules and procedures necessary for safe vehicle operation in these high-traffic zones.

Other options do not provide adequate justification for crossing the MAD line. Emergencies may require immediate action, but they are not an outright condition that grants blanket permission to cross the line; ATC should still be notified when possible. Having a passenger in the vehicle or operating during maintenance hours also do not meet the requirements to ensure safety and compliance. Thus, the approved routes to cross the MAD line are strictly delineated to maintain order and safety on the airside.
