RVSM 14 CFR 91.179 in Controller Talk Posted November 12, 2019 Just simply being an A320 does not make it RVSM capable. Also, aircraft will fly at inappropriate altitudes for a variety of reasons...traffic or for traffic flow. I'm aware of this as the aircraft needs to be certified for RVSM with an annual RVSM pitot/static test. The tolerances for an RVSM pitot/static test are much tighter, and even the skin of the aircraft around the static port is checked for excess ripple, the flushness of the static port flange vs aircraft skin, etc. Most commercial jets such as the A320 are RVSM certified.
