Division 26.8 Alerting and warning system requirements

26.25 Altitude alerting system and assigned altitude indicator — IFR flights
       (1) For an IFR flight, the following aircraft must be fitted with altitude alerting equipment in accordance with subsection (2):
(a) a piston-engine aircraft operating in controlled airspace above FL 150;
(b) an unpressurised turbine-engine aircraft operating in controlled airspace above FL 150;
(c) a pressurised turbine-engine aircraft operating in any controlled airspace.
       (2) For subsection (1), the altitude alerting equipment must:
(a) include an assigned altitude indicator; and
(b) alert the flight crew members if the aircraft approaches a preselected altitude; and
(c) alert the flight crew members, including by an aural or visual warning, if the aircraft deviates from a preselected altitude.
       (3) If an aircraft, other than an aircraft to which subsection (1) applies, is operating under the IFR in controlled airspace, the aircraft must be fitted with altitude alerting equipment that at least includes an assigned altitude indicator.

26.26 Aircraft flown with inoperative altitude alerting equipment — IFR flights
        Despite section 26.25, altitude alerting equipment may be inoperative at the beginning of a flight only if the flight:
(a) begins within 72 hours of the time the equipment was found to be inoperative; and
(b) is from an aerodrome at which there is no facility for the equipment to be repaired or replaced.
