Step 3- Estimate the width of the taxillane needed for each group of aircraft.
Table 8 - 5Apron Taxilanes Width
Taxilane Width
(m)Gate AreaClass (^) X Y
Class I 52 55 114
Class II 70 72 161
Class III 91 79 197
- Sample of calculations for Class III:
Wingspan = 80 m
Width of Taxilane = Wingtip clearance+ spacing of taxilane centerlines+ 3.6 m for service vehicles.
= (0.6 80 +3) + (1.180 +3) + 3.6
= 196.6 m = 197 m
