APPLICABLE AIRWORTHINESS REQUIREMENTS
The applicable airworthiness requirements for approval of instruments and equipment required by
this Part are the following:
(a) Regulation (EC) 748/2012 for:
(1) aeroplanes registered in the EU; and

REQUIRED INSTRUMENTS AND EQUIPMENT THAT DO NOT NEED TO BE APPROVED IN
ACCORDANCE WITH THE APPLICABLE AIRWORTHINESS REQUIREMENTS
The functionality of non-installed instruments and equipment required by this Subpart and that do not
need an equipment approval, as listed in NCC.IDE.A.100(b), should be checked against recognised
industry standards appropriate to the intended purpose. The operator is responsible for ensuring the
maintenance of these instruments and equipment.
NCC.IDE.A.100(c) GM1 Instruments and equipment — general
NON-REQUIRED INSTRUMENTS AND EQUIPMENT THAT DO NOT NEED TO BE APPROVED IN
ACCORDANCE WITH THE APPLICABLE AIRWORTHINESS REQUIREMENTS, BUT ARE
CARRIED ON A FLIGHT
(a) This Guidance Material does not exempt the item of equipment from complying with the
applicable airworthiness requirements if the instrument or equipment is installed in the
aeroplane. In this case, the installation should be approved as required in the applicable
airworthiness requirements and should comply with the applicable Certification
Specifications.
(b) The failure of additional non-installed instruments or equipment not required by this Part
or by the applicable airworthiness requirements or any applicable airspace requirements
should not adversely affect the airworthiness and/or the safe operation of the aircraft.
Examples are the following:
(1) instruments supplying additional flight information (e.g. stand-alone global
positioning system (GPS));
(2) mission dedicated equipment (e.g. radios); and
(3) non-installed passenger entertainment equipment.
