What should a pilot do if they inadvertently enter controlled airspace?

If a pilot inadvertently enters controlled airspace, the appropriate action is to notify air traffic control immediately. This is crucial because controlled airspace is designated for the safe operation of aircraft and is subject to specific regulations. By informing air traffic control, the pilot can receive guidance on how to safely exit the controlled airspace.

Notifying air traffic control helps protect not only the pilot's drone but also other aircraft operating in the area. It enables air traffic controllers to provide necessary instructions, which may include a request to change altitude, a vector to exit the controlled airspace, or a clearance to remain if necessary. Maintaining communication with air traffic control is vital for avoiding potential collisions and ensuring situational awareness for all parties involved.

Other options, like continuing normal operations or landing immediately, might lead to dangerous situations or create further airspace conflicts. Increasing altitude quickly could exacerbate the situation without coordination, as it might lead to entry into different controlled airspace or conflict with other aircraft. Thus, immediately notifying air traffic control is the most responsible and safest action to take.
