Two surveys on the incidence of G-induced loss of consciousness (G-LOC) in U.S. Navy aircraft have been completed. Questionnaires returned (981) indicated an incidence rate of 12.2% in the first survey. A slightly higher incidence rate was found in the second survey based on the 2,459 questionnaires returned. Results indicated that G-LOC is a significant problem in naval aviation in older as well as newer generation aircraft. Age, height, and weight of respondents did not appear to be related to incidence of G-LOC. Results indicated a need for improvement in the anti-G protective system and its use. Different forms of physical fitness training may differentially influence G-tolerance.
关于美国海军飞机上G诱发意识丧失（G-LOC）发生率的两项调查已经完成。回收的问卷（981份）显示，第一次调查中的发生率为12.2%。基于回收的2459份问卷，第二次调查发现发生率略高。结果表明，G-LOC在海军航空领域，无论是老一代还是新一代飞机中都是一个重大问题。受访者的年龄、身高和体重似乎与G-LOC的发生率无关。结果表明，抗G保护系统及其使用需要改进。不同形式的体能训练可能会对G耐受性产生不同的影响。
