* The width of a precision approach runway should not be less than 30 m where the aero-
drome code number is 1 or 2.
† Minimum width of pavement and shoulders when pavement width is less than 60 m.
‡ Symmetrical about the runway centerline.
§ It is recommended that this be provided for the first 150 m from each end of the runway and
that it should be increased linearly from this point to a width of 210 m at a point 300 m from
each end of the runway and remain at this width for the remainder of the runway.
TABLE 6-9 ICAO Runway and Runway Strip Dimensional Standards, m

Under VMC, the FAA requires parallel runway centerline separa-
tions of 700 ft for all aircraft when the operations are in the same direc-
tion and wake vortices are not prevalent. It also recommends increasing
the separation to 1200 ft for airplane design group V and VI runways. If
wake vortices are generated by heavy jets and it is desired to operate on
two runways simultaneously in VMC when little or no crosswind is
present, the minimum distance specified by the FAA is 2500 ft.
For operations under VMC, the ICAO recommends that the min-
imum separations between the centerlines of parallel runways for
simultaneous use disregarding wake vortices be 120 m (400 ft) for
aerodrome code number 1, 150 m (500 ft) for aerodrome code number
2, and 210 m (700 ft) for aerodrome code number 3 or 4 runways.
In IMC conditions, the FAA specifies 4300 ft and ICAO specifies
1525 m (5000 ft) as the minimum separation between centerlines of
