16. Equipment requirements for RVSM operations

A Singapore operator with a special operations approval to conduct RVSM operations must equip every aeroplane used for such operations with navigation equipment capable of —

indicating to the flight crew the flight level being flown;

automatically maintaining a selected flight level;

providing an alert to the flight crew when the aeroplane deviates from the selected flight level with a deviation exceeding the threshold of 90 m (300 ft) above or below the selected flight level; and

automatically reporting to the flight crew the pressure‑altitude if the pressure‑altitude is not automatically reported by the pressure altimeters required for the aeroplane.
