a flight data recorder and cockpit voice recorder system, 1 system is serviceable; and
(c) the aircraft is not operating training or test flights.

7 Assigned altitude indicator and altitude alerting system
       7.1Piston-engined aircraft and unpressurised turbine-engined aircraft operating above 15 000 feet in controlled airspace under the I.F.R. (except night V.M.C.) must be equipped with an altitude alerting system.
       7.2Pressurised turbine-engined aircraft operating in controlled airspace under the I.F.R. (except night V.M.C.) must be equipped with an altitude alerting system.
       7.3Unless equipped with an altitude alerting system, an aircraft operating in controlled airspace under the I.F.R. (except night V.M.C.) must be equipped with an assigned altitude indicator.
       7.4An altitude alerting system or an assigned altitude indicator must be so designed and located that:
(a) it can be readily adjusted for setting from each pilot seat; and
(b) the assigned altitude/flight level display is clearly discernible by day and night to all operating flight crew members whose duties involve altitude/flight level assignment monitoring; and
(c) altitude/flight levels may be pre-selected unambiguously in increments commensurate with levels at which the aircraft may be operated.
       7.5The assigned altitude indicator must be demonstrated to the satisfaction of CASA.
       7.6The altitude alerting system must be demonstrated to the satisfaction of CASA and be capable of:
(a) alerting the pilot upon approaching or departing from a pre-selected level in both climb and descent by aural and/or visual signals in sufficient time to establish level flight at the pre-selected level, except that altitude alerting systems in aircraft first registered in Australia before 1 January 1983 need not alert the pilot when departing from a pre-selected altitude; and
(b) providing the required signals from sea level to the highest operating altitude approved for the aircraft in which it is installed; and
(c) being tested without separate equipment to determine proper operation of the alerting signals; and
(d) accepting necessary barometric pressure settings in millibars if the system or device operates on barometric pressure.

8 Radiation indicator
 All aeroplanes intended to be operated above 49 000 feet must carry equipment to measure and indicate continuously the dose rate of total cosmic radiation being received (i.e. the total of ionizing and neutron radiation of galactic and solar origin) and the cumulative dose on each flight. The display unit must be readily visible to a flight crew member.

9 Ground proximity warning system
       9.1CA turbine-engined aeroplane that:
(a) has a maximum take-off weight of more than 15 000 kg or is carrying 10 or more passengers; and
(b) is engaged in RPT, or charter, operations;
       must not be operated under the I.F.R. unless it is fitted with:
(c) an approved GPWS that has a predictive terrain hazard warning function; or
