Required Instruments
CASR Part 91 MOS Division 26.3
An aeroplane subject operating under the visual flight rules (VFR) by night is subject to the following instrument carriage requirements:
- indicated airspeed;
- pressure altitude;
- magnetic heading;
- time;
- Mach number โ but only for an aeroplane with operating limitations expressed in terms of Mach number;
- turn and slip;
- attitude;
- vertical speed;
- stabilised heading;
- outside air temperature;
- whether the supply of power to gyroscopic instruments (if any) is adequate.
Specifications – Specific Instruments
For an instrument in row 1, then the conditions in row 2 apply.
Row 1 | Row 2 |
---|---|
Indicated airspeed |
The equipment must be capable of being connected to:
|
Pressure altitude |
|
Magnetic heading |
The equipment must be:
|
Time |
|
Turn and slip | The equipment must display turn and slip information, except when a second independent source of attitude information is available in which case only the display of slip information is required. |
Vertical Speed |
The equipment must be capable of being connected to:
|
Stabilised heading | Note – A gyromagnetic type of remote indicating compass meets this requirement if it has a primary power supply and an alternate power supply. |
Navigational Aids
An aeroplane for a VFR flight by night must be fitted with an approved GNSS, or an ADF or VOR.
Approved GNSS
A GNSS system is approved if it manufactured to the technical standard order (TSO) C129A, C145A, C146A or C196A, and hall all provided barometric aiding options connected.
