5.4 s, 1,280 × 720 (1.74 MB) Mahanga {{Information |Description = {{en|1=A 3-wire landing is considered to be the best kind. There are four cables that cross the deck and hitting the third one is safest and means the pilot came in at the perfect spot (really hard to hit, especially at night)
If the aircraft tailhook failed to catch a wire, its landing gear would be caught by a 3-to-4-foot-high (0.9 to 1.2 m) net known as the barrier. If the aircraft caught a wire upon touchdown, the barrier could be quickly lowered to allow aircraft to taxi over it.
Typical diameters are 1/8", 3/16" for residential and 3/16" and 1/4" for commercial applications. [5] There are many different types cable and strand (also referred to as wire rope). Cable and strand is available in galvanized carbon steel, type 304 stainless steel, or the highly corrosion resistant, type 316 stainless steel (best for coastal ...
The safest angle for a ladder is 75.5°; if it is too shallow, the bottom of the ladder is at risk of sliding, and if it is too steep, the ladder may fall backwards. This angle is achieved by following the 4 to 1 rule for a ladder placed on a vertical wall: for every four feet of vertical height, the ladder foot should move one foot from the wall.
It is the use of spreaders (long treads that extend well past the vertical ropes) in a pilot ladder that distinguishes it from a Jacob's ladder. When not being used, the ladder is stowed away, usually rolled up, rather than left hanging. On late 19th-century warships, this kind of ladder would replace the normal fixed ladders on deck during battle.
