-The primary purpose of the altitude chamber is for the subjects to learn what their hypoxia symptoms are. The symptoms of hypoxia are different for each individual, and this training is helpful for aviators to be able to recognize these symptoms during actual flight so as to avoid in-flight oxygen emergencies. Military pilots who fly aircraft at altitudes in excess of 10,000 feet, and civilian pilots who fly unpressurized aircraft above 12,500 feet, must use oxygen equipment. Altitude chamber training is required of [[Military of the United States|U.S. military]] aviators every five years.  The [[Federal Aviation Administration|FAA]] and some larger [[airline]]s also require their pilots to periodically take altitude chamber training.  Anyone with a pilot certificate in the United States who has a [[Pilot certification in the United States#Second class|current Class I or Class II medical certificate]] can normally sign up and receive altitude training from several commercial facilities and a very limited availability from a government facility.

 There are many procedures followed during chamber training for aircrew. Usually new aircrew will undergo a familiarization profile, where the chamber ascends to an altitude of 10,000&nbsp;ft. During the ascent they are instructed on the proper procedure to clear the ears. During ascent, students are asked to yawn and on descent they need to perform the [[valsalva maneuver]]. If they perform the valsalva during ascent, they risk suffering barotrauma of the ear. This is because the ears are susceptible to [[Boyle's Law]].
-There are also other profiles, such a hypoxia training profile, where the chamber ascends to an altitude of 25,000&nbsp;ft. Upon arriving at 25,000&nbsp;ft, students are removed from their oxygen supply two at a time, for around 2 to 3 minutes. During this time, they will be asked to complete simple tasks such as copying shapes on a piece of paper. They are asked during the time off oxygen how they feel. After being placed back on oxygen, they will understand how their judgement was impaired during the time that they were experiencing hypoxia.

 The training goes further with rapid decompression profiles, where the chamber is very rapidly ascended from 8,000&nbsp;ft to 22,000&nbsp;ft within 10 to 20 seconds, to simulate the loss of a cabin door. For fighter pilots this is done from an altitude of 25,000&nbsp;ft to 43,000&nbsp;ft within 5 seconds which simulates the loss of a fighter aircraft's canopy.
