B747-400 OPERATIONS AT INTERNATIONAL AERODROMES
IN THE EUROPEAN REGION — REDUCED SEPARATION
DISTANCES BETWEEN TAXIWAYS AND
TAXIWAYS OR OBJECTS
(Distances expressed in metres)
(Paragraph 42, Part III — AOP of the EUR Basic ANP refers)
Note.— The reduced separation distances presented in columns 4 and 5 are based on the assumption that the cockpit of
aircraft will remain above taxiway/taxilane centre line, lighting/marking.

Remarks:
Specific measures are required and should be published in the AIP.
* Annex 14 maximum lateral deviation.
** Reduced maximum lateral deviation of 2.5 m provided that proper taxiguidance is available (Paragraph 101, Part III — AOP of the EUR Basic ANP refers).
*** Main gear track-in is up to 4 m on curved taxiways.
# Annex 14 safety buffers.
## Safety buffer is reduced due to height-limited objects.
+ Wingtip clearance of an aircraft turning from a taxilane into an aircraft stand should not be less than 7.5 m as recommended in Annex 14, Volume I,
3.12.6.
