Night VFR equipment

Required Instruments

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 — 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: an alternate source of static pressure that: is selectable by a pilot; andincludes a selector that can open or block the aeroplane’s static source and alternative static source at the same time; or a balanced pair of flush static ports.
Pressure altitude	The equipment must: have an adjustable datum scale calibrated in millibars or hPa; andbe calibrated in feet, except that, if a flight is conducted in a foreign country which measures FLs or altitudes in metres, the equipment must be: calibrated in metres; orfitted with a conversion placard or device. The equipment must be capable of being connected to: an alternate source of static pressure that is selectable by a pilot; ora balanced pair of flush static ports.
Magnetic heading	The equipment must be: a direct reading magnetic compass; orboth: a remote indicating compass; and a standby direct reading magnetic compass.
Time	The equipment must display accurate time in hours, minutes and seconds. The equipment must be: fitted to the aircraft; orworn by, or immediately accessible to, the pilot for the duration of the flight.
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: an alternate source of static pressure that is selectable by a pilot; ora balanced pair of flush static ports.
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.
