This advisory circular (AC) contains information on airworthiness, continuing airworthiness, and operations programs for Reduced Vertical Separation Minimum (RVSM) operations. RVSM airspace is any airspace or route between flight level (FL) 290 and FL 410 inclusive where aircraft are separated vertically by 1,000 ft (300 m). This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, for authorization of aircraft and operators to conduct flight in airspace or on routes where RVSM is applied.
