Draft ICAO Circular on NLA.pdf - Airports Council International

-3-
1.2.6 The <strong>Circular</strong> also draws attention to the need for reconsideration of emergency plans to deal
with incidents involving larger aeroplanes, and consequential aspects of rescue and fire fighting.
1.2.7 Aircraft design and certification issues are not directly addressed in this <strong>Circular</strong>. However
national certification requirements may impact facilities, services, or aerodrome infrastructure requirements.
1.2.8 During the early stages of introduction of the NLA, and where it is expected that frequency
of movements will remain low, States may take the decision to consider the statistical implications of such
frequency of movements on safety, in deciding on measures to be implemented.
1.2.9 Aerodromes intending to handle operations of a given NLA may, with approval of the
appropriate authority, provide the facilities with clearances less than those specified in Annex 14, Volume I,
after carrying out aeronautical studies to ensure safety of operations is preserved for that specific aeroplane.
However, facilities meeting code F requirements should be provided in full on all relevant parts of the
movement area whenever new constructions or major redevelopment are undertaken. When planning such
construction or redevelopment, it may be prudent to consider the requirements of future aeroplane types
needing facilities in excess of code F. Guidance in this respect is given in the Aerodrome Design Manual,
Parts 1 and 2. Long term perspective planning to cater to future needs and the ability of the ground
infrastructure to be modified quickly without disruption of ground operations and without compromising
safety, would be advisable.
1.2.10 If NLA operations are contemplated on runways narrower than the 60 m recommended in
Annex 14, Volume I, due considerations should be given to all factors affecting safety, including:
a) the type certification of the NLA concerned in accordance with Annex 8 (see Chapter 5,
paragraph 5.1.2 of this <strong>Circular</strong>);
b) the use of possible mitigation measures discussed in Chapter 4, Section 4.1.2; and
c) local conditions and other operational factors.
1.2.11 Attention is drawn to the fact that the alternative measures, operational procedures and
operating restrictions identified in this document are applicable to those NLA for which the critical
characteristics are shown in Appendix A hereto. Should any of these characteristics change, appropriate
studies will be needed to ensure continued safety of operations.
