• an outside air temperature indicator;
• an attitude indicator (artificial horizon);
• a heading indicator (directional gyroscope);
• a turn and slip indicator except that only a slip indicator is requiredwhen a
second attitude indicator usable throughflight attitudes of 360 degrees of
pitch and roll is installed;
• means of indicatingwhether thepower supply to the gyroscopic
instruments isworking satisfactorily.
Note that for night VMC flights a rate of climb and descent indicator (vertical
speed indicator) and pitot heat are not required.
ALTERNATESTATICSOURCE
The altimeter and airspeed indicator shall be capable of being connected
toeither a normal or an alternate static sourcebut not both sources
simultaneously.
Alternatively, theymay be connected to a balancedpair of flush static ports.
DUPLICATEDGYROPOWERSOURCE
For night VMC charter the attitude indicator, turn and slip indicator shall have
duplicated sources of power supply unless the turn and slip indicator or the
second attitude indicator specified above has a sourceof power independent
of the power operating other gyroscopic instruments. Note that these
duplicated sources of power are not required for aeroplanes engaged in
private and aerial work night VMCoperations.
A gyro-magnetic type of remote indicating compassmay be considered also
tomeet the requirement for a heading indicator specified above provided
that such installation complieswith the duplicated sources of power supply
requirements of the previous paragraph.
EXEMPTIONS
Where an aircraft is not equipped in accordancewith the above, CASAmay
give permission, subject to such conditions (if any), for the aircraft tobe flown
under VFR.
