In-flight loss of consciousness in a fighter aircrew – G-LOC or No G-LOC conundrum

The differential diagnosis for inflight loss of consciousness in a fighter pilot is G-induced Loss Consciousness (G-LOC) as it physiological and 10–20% pilots may experience during their career. However, very difficult to establish the many cases. Three cases in-flight episodes (LOC) have been discussed paper highlighting how investigate such G-LOC. where two were considered case G-LOC based on circumstantial evidence data from flight recorder. one was diagnosed be LOC (Inv). One did not benefit high-G training he repeatedly experienced “GLOC” at low G levels while wearing Anti-G Suit performing an Straining Maneuver (AGSM). He recommended unfit flying. Another aircrew experiencing due incorrect technique AGSM had undergone “high-G training.” After correction technique, could successfully meet qualifying requirements 9G high training. third LOC, exposure.
