Weather. Prevailing weather in the landing area should be favorable. In particular, there must be a determination of wind direction and velocity, and of conditions restricting visibility such as ground fog, haze, or low-hanging cloud formations.

Size. The required size of LZs varies according to the aircraft used. Safe operations require the following minimum dimensions (Figures 12 and 13). Medium aircraft. 3,000 feet (920 meters) in length and 100 feet (30 meters) in width (150 feet or 45 meters at night).

Light aircraft. 1,000 feet (305 meters) in length and 40 feet (15 meters) in width (150 feet or 45 meters at night).

In addition to the basic runway dimensions, and to provide a safety factor, these extra clearances are required. A cleared surface capable of supporting the aircraft, extending from each end of the runway, and equal to 10 percent of the runway length.

A 50-foot (15 meter) strip extending along both sides of the runway and cleared to within three feet of the ground.
