Location Signs
Location signs are used to identify the taxiway or runway on which an
aircraft is located (Fig. 8-32a and 8-32b). These signs consist of a yellow
inscription and border on a black background. Location signs are also
used to identify the boundary of the runway safety area or obstacle-
free zones (Fig. 8-32c), or the instrument landing system critical area
(Fig. 8-32d) for a pilot exiting a runway. In the latter cases the signs con-
sist of a black inscription and border on a yellow background and the
inscription on the sign is the same as relevant holding line marking.
Direction Signs
Direction signs are used to indicate the direction of other taxiways
leading out of an intersection. These signs are used as taxiway direction
sign (Fig. 8-33) and runway exit sign. The signs have black inscrip-
tions and borders on a yellow background and always contain arrows.
The arrows are oriented in the approximate direction of the turn
required. These signs should not be located with holding position
signs and should not be located between the holding line and the runway.
