7.3.1 Taxiway and Taxilane Separation Requirements
To provide a margin of safety in the airport operating areas, the traffic ways must be
separated sufficiently from each other and adjacent obstructions. The minimum separation
between taxiways, between a taxiway and a taxilane, or between a taxiway and a fixed or
movable object, are presented in Table 7- 9.
The values indicated in Table 7- 9 are based on the required wingtip clearance, which is a
function of the wingspan and is thus determined by ADG (VI).
