4.  VFR communication equipment

4.1 Each aircraft operating under VFR in controlled airspace shall be equipped with radio communications equipment that meets the standards specified in Annex 9 and that is capable of providing continuous two-way communications with an appropriate ATC unit, unless the pilot of the aircraft is authorised by ATC to operate under VFR without radio communication.
4.2 Each aircraft operating under VFR outside controlled airspace shall be equipped with radio communication equipment that meets the standards specified in Annex 9 if the equipment is to be used for communication with any ATS unit.

5.  IFR instruments and equipment

Each powered aircraft issued with an airworthiness certificate and operating under IFR, shall be equipped in accordance with paragraph 3 and 4 as well as the means of indicating:

a) aircraft attitude, by gyroscopic or inertial means;

b) magnetic heading, by gyroscopic or inertial means;

c) that the power supply to any gyroscopic instruments is adequate;

d) sensitive pressure altitude, in metre /feet/, adjustable for barometric pressure in hectoPascals or millibars;

e) outside air temperature;

f) time in hours, minutes and seconds;

g) airspeed in knots, with a means of preventing malfunctioning due to either condensation or icing; and

h) rate of climb and descent.

6.  IFR communication and navigation equipment

6.1 Each aircraft operating under IFR shall be equipped with communication equipment that meets the requirements of paragraph 7 and is capable of providing continuous two-way communication with an appropriate ATS unit or aeronautical telecommunications facility.
6.2 Each aircraft operating under IFR shall be equipped with a navigation system which:

a) meets the requirements specified in Paragraph 7;

b) will enable the aircraft to proceed in accordance with:

- the flight plan;

- the designated RNP airspace where applicable;

- .... the requirements of ATC.
