Toward Precision Aerospace Medicine: A Multi-Level Framework for +Gz Tolerance and Pilot Safety

Traditionally, the field of aerospace medicine has focused on establishing generalized standards for +Gz testing and training to ensure pilots' +Gz tolerance and flight safety [1].However, the existing research frequently debates training modalities without sufficient regard for the specific +Gz load being sustained.As +Gz loads increase in modern aviation, the required levels of body composition and physical fitness-and consequently the type, intensity, and structure of training-must undergo a fundamental shift.This lack of specificity obscures the clear physiological demands of high-performance maneuvers and, ultimately, diminishes the effectiveness of pilot training.Indeed, a critical limitation remains in how human physiology is integrated with increasingly evolving flight platforms.Furthermore, we currently face a "Safety Paradox".While modern avionics systems-such as Ground Collision Avoidance System (GCAS), Automatic Collision Avoidance System (ACAS), and near-infrared sensor-based monitoring-are increasingly effective at preventing G-LOC, their high degree of automation risks fostering a reliance that may mask a degradation [2] in the pilot's intrinsic physi- Toward Precision Aerospace Medicine
