G-induced loss of consciousness (G-LOC) is defined as "a state of altered perception wherein (one's) awareness of reality is absent as a result of sudden, critical reduction of cerebral blood circulation caused by increased G force." This phenomenon was first identified in Great Britain in World War I (circa 1918-1919) as "fainting in the air." In the United States G-LOC was first encountered in 1922 during the Pulitzer Trophy Air Race. Although recognized during World War II as an operational hazard for fighter aircraft, the invention of the pneumatic anti-G suit reduced concern about G-LOC at that time. A 1984 survey of pilots of high performance aircraft has shown G-LOC to be an operational problem--probably one that has caused aircraft mishaps for several years. The concern of this panel was to focus on various approaches in reducing the G-LOC hazard.
重力导致的意识丧失（G-LOC）被定义为“一种感知改变的状态，即由于重力增加导致脑血液循环突然严重减少，从而使人对现实的意识缺失”。这种现象于第一次世界大战期间（约1918 - 1919年）在英国首次被确认为“空中昏厥”。1922年，在美国普利策奖杯空中竞赛中首次遇到G-LOC。尽管在第二次世界大战期间它被认为是战斗机的一种作战危险，但当时气动抗荷服的发明降低了对G-LOC的担忧。1984年对高性能飞机飞行员的一项调查表明，G-LOC是一个作战问题——可能是一个多年来导致飞机事故的问题。该小组关注的是集中探讨减少G-LOC危险的各种方法。
