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.

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.
NCO.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.
NCO.IDE.A.135 AMC1 Flight crew interphone system
GENERAL
(a) The flight crew interphone system should not be of a handheld type.
(b) A headset consists of a communication device that includes two earphones to receive
and a microphone to transmit audio signals to the aeroplane’s communication system.
To comply with the minimum performance requirements, the earphones and microphone
should match the communication system’s characteristics and the flight crew
compartment environment. The headset should be adequately adjustable in order to fit
the pilot’s head. Headset boom microphones should be of the noise cancelling type.
(c) If the intention is to utilise noise cancelling earphones, the pilot-in-command should
ensure that the earphones do not attenuate any aural warnings or sounds necessary for
alerting the flight crew on matters related to the safe operation of the aeroplane.

HEADSET
The term ‘headset’ includes any aviation helmet incorporating headphones and microphone worn by
a flight crew member.

(1) it is a supplementary loop belt manufactured with the same techniques and the
same materials as the approved safety belts; or
(2) it complies with (b).
(b) Provided the CRD can be installed properly on the respective aircraft seat, the following
CRDs are considered acceptable:
(1) CRDs approved for use in aircraft according to the European Technical Standard

Aircraft’ (TÜV/958-01/2001) bearing the label ‘For Use in Aircraft’; or
(iii) Other technical standard acceptable to the competent authority. The child
seat should hold a qualification sign that it can be used in aircraft.
(3) Child seats approved for use in motor vehicles on the basis of the technical
standard specified in (i). The child seat must be also approved for use in aircraft on
the basis of the technical standard specified in either point (ii) or point (iii):.
