An overall reduction in the prevalence of G-induced alteration of consciousness incidents was observed in UK military aviation, with high-G recency identified as an important risk factor.
Observational
High-G recency is an important risk factor for G-induced alterations of consciousness in UK frontline jet pilots, suggesting a need for additional risk assessment for the G-layoff effect.
An overall reduction in prevalence of G-induced alteration of consciousness incidents was observed, with frontline jet pilots reporting a higher proportion of incidents over time. The reported importance of high-G recency as a risk factor suggests that additional risk assessment for the G-layoff effect may be beneficial for UK frontline jet pilots.
