Aircraft with specially certified altimeters and autopilots may fly in RVSM (Reduced Vertical Separation Minimum) airspace. Now, aircraft are able to safely operate in RVSM airspace because they are being manufactured in accordance to RVSM standards. If your aircraft was certified for RVSM operations by the factory during production or if your aircraft was certified for RVSM operations after receiving an initial airworthiness certification, the Heavy Metal Air staff will perform your inspection and maintenance in accordance to the aircraft’s OEM maintenance manual.
