For such operations, the recovery party Is usually di apera ad along the length oí the anticipated impact area. The members ftpot each parachute as 11 descend» and move to the landing point. They then recover all paraolaute equipment and Cargo, moving to a predetermined assembly area with the infiltrated personnel or equipment.

If the LZ la located In terrain above 4,000 feet (1,220 meters) and/or areas with a very high temperature the minimum length* ahould be Increased as followa:

AM 10 percent to minimum» fore»oh 1,000 feet (305 meter»).

2. Add 10 percent to minimum for the altitude for temperature» over 90°F, Add 20 percent for temperatures over 100°T, (380c).

(o) Pockets or small valleys completely surrounded by hills are uaual-ly unsuitable for operations by fixed-wing aircraft.

(d) Although undesirable, sites with only a single approach can be used. II la mandatory when uolng such sites that:

1. All takooffa and landings are made upwind.

2. There 1b sufflolent clearance at o 1thor end of the LZ to permit s level 180° turn to either side within a radius of 3 mlloe (5 kilometer») for medium aircraft (1 mile for light aircraft).


(2) Weather. Prevailing weathsr in the landing area ahould be favorable. In particular, there must be a determination of wind direction and velocity, and of condltlona reetrictlng vielbility euch as ground fog, hare, or low-hanging cloud formalloae.

(3) Size. TherequiredalzeofLZ'a varies according to tie aircralt used. Safe operations require the following minimum dimensions (Figures 12 and 13).

(a) Medium aircraft. 3,000 feet (92C meter») in length and 100 feet (30 metere) In width (150 feet or 45 meters at night).

(b) Light aircralt. 1,000 feet (305 meters) In length and 40 ieet (13 meters) Id width (150 feet or 45 meters at night).

(c) In addition to the basic runway dimensions, and to provide a safety factor, these extra clearances are required.

b. Selection Criteria

(1] Oealrahle terrain feature«!

(a) LZ'a should be located In flat or rolling terrain.

{b) Level plateaus of sufficient sire can he uSBd. Due lo decreased air density, landings at higher elevutlona require increased minimum LZ dimension».

1. A cleared aurf ace capable of aupporting the aircraft, extending from each end of the runway, and equal to 10 percent of the runway length.

2. A 50-foot (19 meter) strip extending along both sides of the runway and cleared to within three feet of the ground.
