What is Pressure suit?
A '''pressure suit''' is an [[environmental suit]] worn when [[atmospheric pressure]] gets too low or too high to be survivable without. The minimum survivable pressure corresponds with an [[altitude]] of 15,000 meters above the surface of [[Earth]], where the pressure dips to 102 [[millibar]]s. Pressure suits must thus be worn by [[pilot]]s who fly at high altitudes, unless the cabin of the [[airplane]] is pressurized. There's '''partial pressure suits''' and '''full pressure suits''' [[spacesuit]]s are examples of the latter. Conversely, a hard [[diving suit]] protects against the extreme pressures deep below the surface of the [[ocean]] (below around 400 metres). [[Category:Environmental suits]] {{stub}}
