Airport Markings and Signs

Remote pilots need to be familiar with standard airport markings and signs to exercise vigilant collision
avoidance, practice sound see-and-avoid procedures, and not interfere with manned aircraft operations.

Runway numbers and letters are determined from the approach direction. The number is the
magnetic heading of the runway rounded to the nearest 10⁰. For Example, a runway facing an
azimuth of 183⁰ would result in a runway number of 18; a runaway with a magnetic azimuth of
076⁰ would result in a runway numbered 8. If there is more than one runway facing the same
direction, the runway will have letters to differentiate between left (L), right (R), or center (C), see
Figure 2-4/

The designated beginning of the runway that is available and suitable for the landing of aircraft is
called the threshold (Figure 2-5a). A threshold that is not at the beginning of the full-strength
runway pavement is a displaced threshold. The paved area behind the displaced threshold is
marked by arrows (Figure 2-5b) and is available for taxing, takeoff, and landing rollout, but is not
to be used for landing usually because of an obstruction in the approach path, See Figure 2-5.

Stops are found extending beyond some usable runways. These areas are marked by chevrons,
and while they appear usable, they are suitable only as overrun areas, See Figure 2-6.

A closed runway which is usable for various reasons and may be hazardous, even though it may
appear usable, will be marked by an “X”.

A basic runway may only have centerline markings and runway numbers. Airports supporting
instrument operations, higher volumes, and larger aircraft may use additional runway markings,
See Figure 2-7.
