If required equipment fails while operating in RVSM airspace, what should the pilot do?

In Reduced Vertical Separation Minimum (RVSM) airspace, the ability to maintain safe vertical separation between aircraft is critically dependent on the proper functioning of specific equipment, such as the altitude-keeping system. If this equipment fails, the safety of the flight could be compromised.

Notifying the controlling agency as soon as possible is the correct action to take because it allows air traffic control (ATC) to assess the situation and make necessary adjustments to ensure continued safety in the airspace. ATC can provide instructions, reroute other aircraft, or prioritize your landing to prevent conflicts with other traffic. Communication is key in maintaining safety and efficiency, especially in a highly regulated environment like RVSM airspace.

Continuing the flight as planned or waiting for further instructions can lead to dangerous situations, as it might result in a failure to adequately separate from other aircraft. Landing at the nearest airport may not always be the best immediate response depending on the situation; it could put the aircraft in greater danger if there are other risks associated with landing. Proactive communication with ATC is essential to manage the implications of the failure effectively.
