9-5.2.6
Each designation and its associated arrow in a direction sign array should
be delineated from the other designations in the array by a black vertical border. Where
appropriate, a location sign may provide this delineation.
9-5.2.8
Destination signs are never grouped with other signs in a sign array.
Destination signs may be installed on the back side of a direction sign on the far side of
an intersection when the destination referred to is straight ahead. At intersections or
junctions of runways, taxiways, or runways and taxiways, where there are alternate
routes to a particular destination from a given direction of travel, indicate only one route
on the destination sign.
9-5.2.9
Mark outbound routes from their beginning to their termination point with
destination signs showing the appropriate runway(s) designation. Outbound routes
usually begin at the entrance of a taxiway from an apron area; its termination point is
the takeoff end of the appropriate runway. Outbound destination signs may show more
than one runway destination number if the direction of travel on a taxiing route is the
same to all the runway destinations shown on the sign. In such cases, separate any pair
of runway designation numbers by a circular dot.
9-5.2.10
Mark inbound routes from their beginning with destination signs showing
the appropriate symbols. Inbound routes usually begin at the entrance to a taxiway from
a runway. Mark inbound traffic routes at the beginning with appropriate destination
areas on the airfield as required. Typical examples are "APRON," "FUEL," "MIL," and
"CARGO". with an arrow indicating the route. This is a general guide and may be varied
to meet local conditions, ground traffic, and variations in airport layout.
9-5.3
It is recommended that all mandatory taxiway guidance and information
signs, and location signs be of the same size for a runway and associated taxiway
complex. FAA Size 3 signs are recommended for facilities that have Category I
operational capability, and for other higher volume airfields. An exception can be made
at a particular location where a sign must be positioned closer to a runway or taxiway
allowed for a Size 3 sign. In this case a smaller sign may be installed within its allowable
distance from the surface.
9-5.4
Examples of sign layouts are shown in Figures 9-4 and 9-5. Example for
positioning a TACAN checkpoint sign is shown in Figure 9-6.
