Lesson 3.1 Runway Markings
1. The number at the start of each runway indicates its magnetic alignment divided by 10°; e.g., Runway 26 indicates 260° magnetic; Runway 9 indicates 090° magnetic.
a. Runways are numbered by the direction in which they point.
2. A displaced threshold is a threshold (marked as a broad solid line across the runway) that is not at the beginning of the full strength runway pavement. The remainder of the runway, following the displaced threshold, is the landing portion of the runway (shown in Figure A below).
a. The paved area before the displaced threshold (marked by arrows) is available for taxiing, the landing rollout, and takeoff of aircraft.
3.
4. Chevrons (illustrated in Figure B above) mark any surface or area extending beyond the usable runway that appears usable but that, due to the nature of its structure, is unusable runway.
a. This area is not available for any use, not even taxiing.
5. Closed runways are marked by an “X” on each runway end that is closed.
6. Runway holding position markings indicate where an aircraft is supposed to stop. They consist of four yellow lines, two continuous and two dashed, extending across the width of the taxiway or runway. The solid (continuous) lines are always on the side where the aircraft is to hold.
