During flight, if contacted by ATC regarding a potential airspace violation, what is the pilot’s best immediate response?

The correct response in this situation is to acknowledge the Air Traffic Control (ATC) communication concerning a potential airspace violation and continue with the planned flight. Compliance with ATC guidance is crucial for maintaining safety and efficiency in air traffic. Acknowledging the concern shows that the pilot is aware of ATC's directive and is following proper protocol.

Continuing with the planned flight, provided that it is safe to do so and the pilot is not violating any air traffic regulations, allows for a more controlled approach to resolving the situation. The pilot can then monitor further instructions from ATC, who may provide additional guidance or instructions to navigate around the restricted airspace. This approach emphasizes the importance of ATC communication and established flight safety protocols.

The other options suggest actions that could lead to confusion or further complications. Changing altitude abruptly without direction from ATC might inadvertently lead to a more significant violation or unsafe conditions. Requesting a flight plan diversion might not be necessary if the pilot is not actively infringing upon airspace restrictions and could distract from promptly addressing ATC’s inquiry. Reporting the issue to authorities after landing may be a good practice but does not address the immediate need to respond to ATC’s request during the flight.
