                                                                                     (a) have an adjustable datum scale calibrated in millibars or hPa; and
                                                                                     (b) be calibrated in feet, except that, if a flight is conducted in a foreign country that measures flight levels or altitudes in metres, the equipment must be calibrated in metres or fitted with a conversion placard or device.
                                                                                     2. For an aeroplane that has an MTOW of not more than 5 700 kg, the equipment must be capable of being connected to:
                                                                                     (a) an alternate static system that:
                                                                                     (i) is selectable by a pilot; and
                                                                                     (ii) includes a selector that can open, or block, the aeroplane's static source and alternative static source at the same time; or
                                                                                     (b) a balanced pair of flush static ports.
                                                                                     3. For an aeroplane that has an MTOW of more than 5 700 kg, the equipment must be capable of being connected to:
                                                                                     (a) an alternate static system that:
                                                                                     (i) is selectable by a pilot; and
                                                                                     (ii) includes a selector that can open, or block, the aeroplane's static source and alternative static source at the same time; or
                                                                                     (b) 2 independent static sources, each consisting of a balanced pair of flush static ports.
