Aerodrome code 3 75 75 90 *,† 90 *,† 75
Aerodrome code 4 75 75 90 *,† 90 *,† 75

* This distance may have to be increased to avoid interference with radio aids; for a preci-
sion instrument category III runway this increase may be in the order of 50 m.
† If a holding bay or a taxiway holding position is at a lower elevation compared to the
runway threshold the distance may be decreased by 5 m for every meter the holding
bay or holding position is lower than the threshold, contingent upon not interfering
with the inner transitional surface; if a holding bay or a taxiway holding position is
at a higher elevation compared to the runway threshold the distance should be
increased by 5 m for every meter the holding bay or holding position is higher than
the threshold.
