~ Regulation SPO - ANNEX VIII - Specialised Operations Centrik

without reference to one or more additional instruments, shall be, in addition to (a) and (b),
equipped with a means of preventing malfunction of the airspeed indicating system
required in (a)(4) due to condensation or icing.
(e) Whenever two pilots are required for the operation, aeroplanes shall be equipped with an
additional separate means of displaying the following:
(1) barometric altitude,
(2) indicated airspeed,
(3) slip, or turn and slip, as applicable,
(4) attitude, if applicable,
(5) vertical speed, if applicable
(6) stabilised heading, if applicable, and
(7) Mach number whenever speed limitations are expressed in terms of Mach number, if
applicable.
SPO.IDE.A.120 & SPO.IDE.A.125 Operations under VFR & operations under IFR — flight and navigational instruments and associated
AMC1 equipment
INTEGRATED INSTRUMENTS
(a) Individual equipment requirements may be met by combinations of instruments, by
integrated flight systems or by a combination of parameters on electronic displays. The
information so available to each required pilot should not be less than that required in the
applicable operational requirements, and the equivalent safety of the installation should be
approved during type certification of the aeroplane for the intended type of operation.
(b) The means of measuring and indicating turn and slip, aeroplane attitude and stabilised
aeroplane heading may be met by combinations of instruments or by integrated flight
director systems, provided that the safeguards against total failure, inherent in the three
separate instruments, are retained.
SPO.IDE.A.120 AMC2 Operations under VFR — flight and navigational instruments and associated equipment
LOCAL FLIGHTS
For flights that do not exceed 60 minutes’ duration, that take off and land at the same aerodrome, and
that remain within 50 NM of that aerodrome, an equivalent means of complying with SPO.IDE.A.120(b)
(1)(i), (b)(1)(ii) may be:
(a) a turn and slip indicator;
(b) a turn co-ordinator; or
(c) both an attitude indicator and a slip indicator.
SPO.IDE.A.120 GM1 Operations under VFR — flight and navigational instruments and associated equipment
SLIP INDICATION
Non-complex motor-powered aeroplanes should be equipped with a means of measuring
anddisplaying slip.
SPO.IDE.A.120(a)(1) & Operations under VFR & operations under IFR — flight and navigational instruments and associated
SPO.IDE.125(a)(1) equipment
MEANS OF MEASURING AND DISPLAYING MAGNETIC HEADING
The means of measuring and displaying magnetic direction should be a magnetic compass or
equivalent.
SPO.IDE.A.120(a)(2) & Operations under VFR & operations under IFR — flight and navigational instruments and associated
SPO.IDE.A.125(a)(2) AMC1 equipment
MEANS OF MEASURING AND DISPLAYING THE TIME — COMPLEX MOTOR-POWERED
AIRCRAFT
An acceptable means of compliance is a clock displaying hours, minutes and seconds, with a
sweepsecond pointer or digital presentation.
MEANS OF MEASURING AND DISPLAYING THE TIME — OTHER-THAN COMPLEX MOTOR-
POWERED AIRCRAFT
An acceptable means of measuring and displaying the time in hours, minutes and seconds may be a
wrist watch capable of the same functions.
SPO.IDE.A.120(a)(3) & Operations under VFR operations & operations under IFR — flight and navigational instruments and
SPO.IDE.A.125(a)(3) AMC1 associated equipment
CALIBRATION OF THE MEANS OF MEASURING AND DISPLAYING PRESSURE ALTITUDE
The instrument measuring and displaying barometric altitude should be of a sensitive type calibrated in
feet (ft), with a sub-scale setting, calibrated in hectopascals/millibars, adjustable for any barometric
pressure likely to be set during flight.
SPO.IDE.A.120(a)(4) & Operations under VFR & operations under IFR — flight and navigational instruments and associated
SPO.IDE.A.125(a)(4) AMC1 equipment
CALIBRATION OF THE INSTRUMENT INDICATING AIRSPEED
(a) The instrument indicating airspeed should be calibrated in knots (kt).
(b) In the case of aeroplanes with a maximum certified take-off mass (MCTOM) below 2 000
kg,
calibration in kilometres per hour (kph) or in miles per hour (mph) is acceptable when such
units
are used in the AFM.
