Night VFR equipment
Night VFR equipment CAO 20.18 Appendix 4
In addition to day VFR equipment requirements, flights at night in VMC must have:
- an OAT indicator
- an attitude indicator
- a heading indicator
- a turn and slip indicator except that only a slip indicator is required when a second attitude indicator usable through flight attitudes of 360 degrees of pitch and roll is installed and
- a means of indicating whether power supply to the gyroscopic instruments is working satisfactorily.
Furthermore, as set out below, aircraft flown under VFR at night require (CAO 20.18 Appendix 5):
- a landing light
- illumination for all instruments and equipment used by the flight crew that are essential for the safe operation of the aircraft
- lights in all passenger compartments
- an electric torch for each crew member and
- such other equipment as CASA directs in the interests of safety.
In respect of an aircraft that is not equipped as above, CASA may give permission, subject to such conditions (if any) as are specified in the permission, for the aircraft to be flown under VFR by day or by night.
Serviceability CAO 18.104.22.168A
All instruments and equipment fitted to an aircraft must be serviceable before take-off unless:
- flight with unserviceable instruments or equipment has been approved by CASA, subject to such conditions as CASA specifies or
- the unserviceability is permitted under the provisions of a permissible unserviceability schedule.
Where a flight is conducted with unserviceable instruments or equipment under the provisions of CAO 20.18, the unserviceable instruments or equipment shall be prominently placarded ‘Unserviceable’ or removed from the aircraft.
Where an instrument or piece of equipment performs more than one function, it is permissible
to placard as unserviceable only the function(s) which are unserviceable.
A charter, aerial work or private operator may elect to have a permissible unserviceability schedule. Charter or aerial work operators must incorporate the permissible unserviceability schedule in the operator’s operations manual.
