Note:  1.  The separation distances are based on the concept of the wing of the aeroplane, centred on the parallel taxiway, remaining clear of the runway strip of standard width.

            2.   The taxiway centreline to runway centreline separation distances have been determined using the maximum runway strip width required for the particular category and code of runway.

            3.   ILS installations may also influence the location of taxiways due to interferences to ILS signals by a taxiing or stopped aircraft. Information on critical and sensitive areas surrounding ILS installations is contained in Annex 10, Volume I, Attachment C of the Chicago Convention.

Table 6.5-1: Aircraft parking positions – Minimum separation distance

Code letter for aircraft	From centre line of aircraft parking taxilane to the centreline of a parallel aircraft parking taxilane	From centre line of aircraft parking position taxilane to object	From wingtip of aircraft on aircraft parking position to object
A	19.5 m	12.0 m	3.0 m
B	28.5 m	16.5 m	3.0 m
C	40.5 m	22.5 m	4.5 m
D	59.5 m	33.5 m	7.5 m
E	72.5 m	40 m	7.5 m*
F	87.5 m	47.5 m	7.5 m*

6.5.2.1A   An aircraft parking position taxilane must be separated from another aircraft parking position taxilane by a distance that is not less than that determined using Table 6.5 1.

6.5.2.1B   Each minimum separation distance mentioned in column 4 of Table 6.5-1 that is accompanied by an asterisk, must be read as 10 metres if free moving parking is used.

Note:Free moving parking is parking on an apron that does not have designated parking positions.
