Attachment E
IMPACT OF OPERATIONS OF
SPECIFIC AEROPLANES ON AERODROMES
(Paragraph 98, Part III — AOP of the EUR Basic ANP refers)
ANNEX 14, VOLUME I
1. With the introduction of the B 747-400, the
Council of ICAO adopted 65 m as the upper limit of wing
span for code letter E in Table 3-1 of Annex 14, Volume I.
This table includes the requirements for the physical
characteristics of aerodromes such as increased separation
distances between runway and parallel taxiway, parallel
taxiways, taxiway to object and aircraft stand taxilane to
object, as shown below:
SURVEY ON B 747-400 OPERATIONS
IN THE ICAO EUROPEAN REGION
3. A regional survey on B 747-400 operations at
international aerodromes was conducted by the European
Office of ICAO in October 1989.
RESULTS OF THE ICAO SURVEY
4. The ICAO survey:

47.5 m

42.5 m
(40.0 m)
— indicates that lower separation distances, used at some
major aerodromes, do not effect the safety of NLA
operations.
(Distances in brackets refer to those approved by
Amendment 38 to Annex 14.)
2. Lower separation distances at an existing
aerodrome may be permitted if an aeronautical study
indicates that such lower separation distances, together with
the conditional implementation of specific measures, would
not effect the safety and the regularity of operations of
aeroplanes.
Note.— Guidance on relevant factors which may be
considered in an aeronautical study is given in the
Aerodrome Design Manual, Part 2 (Doc 9157).
5. The “ICAO Survey” showed the NLA-related
problems concerning terminal, apron and manoeuvring area
as well as the reduced separation distances, used at some
aerodromes.
TERMINAL (Building)
6. Terminal limitations such as check-in concourse,
waiting lounge, customs, security, baggage claim area, gate
occupancy, car parking, access roads, etc., are related to
passenger capacity of aircraft. Hence the B 747-300 (wing
span 60 m) problems occurring at airports are not B
747-400 (NLA)-related.
