What is the appropriate action if a DME malfunction occurs during a flight?

When a DME (Distance Measuring Equipment) malfunction occurs during a flight, notifying Air Traffic Control (ATC) and continuing to the nearest airport is the appropriate action because it ensures both safety and compliance with operational protocols. Informing ATC allows them to provide necessary assistance, which may include radar vectors or alternative routing, ensuring that the aircraft can safely navigate to a nearby airport.

This action is critical for maintaining situational awareness and facilitating an effective response to the situation. ATC can also notify other aircraft in the vicinity about the malfunction, thereby enhancing overall air traffic safety. Continuing directly to the nearest airport allows for a timely landing, minimizing the potential impacts of the malfunction on the flight's safety and efficiency.

In contrast, other options may compromise safety. Continuing without reporting could lead to further complications if the situation worsens. Requesting immediate assistance from ground control is unnecessary, as in-flight communication with ATC is the standard protocol. Making a correction to the flight path without notifying ATC may hinder coordination and situational awareness, potentially leading to an unsafe flight environment.
