SPO.IDE.A.130 Terrain awareness warning system (TAWS)
Turbine-powered aeroplanes with a maximum certified take-off mass (MCTOM) of more than 5 700 kg
or an MOPSC of more than nine shall be equipped with a TAWS that meets the requirements for:
(a) class A equipment, as specified in an acceptable standard, in the case of aeroplanes for
which the individual certificate of airworthiness (CofA) was first issued after 1 January
2011; or
(b) class B equipment, as specified in an acceptable standard, in the case of aeroplanes for
which the individual CofA was first issued on or before 1 January 2011.

Centrik Regulations Team note: This item was due to be amended by CIR (EU) 2018/1042 however,
the applicability date was delayed by CIR (EU) 2020/745 until after the EU Exit date. Therefore, the
amendments did not enter into UK Law and were not applied to this item.
SPO.IDE.A.130 AMC1 Terrain awareness warning system (TAWS)
EXCESSIVE DOWNWARDS GLIDESLOPE DEVIATION WARNING FOR CLASS A TAWS
The requirement for a Class A TAWS to provide a warning to the flight crew for excessive downwards
glideslope deviation should apply to all final approach glideslopes with angular vertical navigation
(VNAV) guidance, whether provided by the instrument landing system (ILS), microwave landing
system (MLS), satellite-based augmentation system approach procedure with vertical guidance
(SBAS APV (localiser performance with vertical guidance approach LPV)), ground-based
augmentation system (GBAS (GPS landing system, GLS)) or any other systems providing similar
guidance. The same requirement should not apply to systems providing vertical guidance based on
barometric VNAV.
SPO.IDE.A.130 GM1 Terrain awareness warning system (TAWS)
ACCEPTABLE STANDARD FOR TAWS
An acceptable standard for Class A and Class B TAWS may be the applicable European Technical
Standards Order (ETSO) issued by the Agency or equivalent.
SPO.IDE.A.131 Airborne collision avoidance system (ACAS II)
Unless otherwise provided for by Regulation (EU) No 1332/2011, turbine-powered aeroplanes with an
MCTOM of more than 5700 kg shall be equipped with ACAS II.
SPO.IDE.A.132 Airborne weather detecting equipment — complex motor-powered aeroplanes
The following aeroplanes shall be equipped with airborne weather detecting equipment when operated
at night or in IMC in areas where thunderstorms or other potentially hazardous weather conditions,
regarded as detectable with airborne weather detecting equipment, may be expected to exist along the
route:
(a) pressurised aeroplanes;
(b) non-pressurised aeroplanes with an MCTOM of more than 5 700 kg.
SPO.IDE.A.132 AMC1 Airborne weather detecting equipment — Complex Motor-Powered Aeroplanes
GENERAL
The airborne weather detecting equipment should be an airborne weather radar. However, for
propeller-driven pressurised aeroplanes with an MCTOM not more than 5 700 kg and an maximum
certified seating configuration of not more than nine, other equipment capable of detecting
thunderstorms and other potentially hazardous weather conditions, regarded as detectable with
airborne weather radar equipment, are also acceptable.
SPO.IDE.A.133 Additional equipment for operations in icing conditions at night — complex motor- powered aeroplanes
(a) Aeroplanes operated in expected or actual icing conditions at night shall be equipped with a
means to illuminate or detect the formation of ice.
(b) The means to illuminate the formation of ice shall not cause glare or reflection that would
handicap flight crew members in the performance of their duties.
SPO.IDE.A.135 Flight crew interphone system
Aeroplanes operated by more than one flight crew member shall be equipped with a flight crew
interphone system, including headsets and microphones for use by all flight crew members.
SPO.IDE.A.135 AMC1 Flight Crew Interphone System
TYPE OF FLIGHT CREW INTERPHONE
The flight crew interphone system should not be of a handheld type.
SPO.IDE.A.140 Cockpit voice recorder
(a) The following aeroplanes shall be equipped with a CVR:
(1) aeroplanes with an MCTOM of more than 27 000 kg and first issued with an
individual CofA on or after 1 January 2016; and
(2) aeroplanes with an MCTOM of more than 2 250 kg:
(i) certified for operation with a minimum crew of at least two pilots;
(ii) equipped with turbojet engine(s) or more than one turboprop engine; and
(iii) for which a type certificate is first issued on or after 1 January 2016.
(b) The CVR shall be capable of retaining data recorded during at least:
(1) the preceding 25 hours for aeroplanes with an MCTOM of more than 27 000 kg and
first issued with an individual CofA on or after 1 January 2022; or
(2) the preceding 2 hours in all other cases.
(c) The CVR shall record with reference to a timescale:
(1) voice communications transmitted from or received in the flight crew compartment
