Combating Fighter Pilot Fatigue

Pilot fatigue is a constant threat to all aircrew. There are particular risk factors for those flying high-performance fighter platforms. Flying high-G sorties is physically exhausting. This is an tiring business and even well-rested pilots will find themselves fatigued from the physical and mental demands of combat flight operations. In order[...Click Below to Read More]

Be a Better G-Monster: The Anti-G Straining Maneuver (AGSM)

This installment will review the effect of G’s on the human body, the Anti-G Straining Maneuver (AGSM) and how you as the modern fighter pilot can decrease the likelihood of being the victim of a G-LOC (G-induced loss of consciousness). With the introduction of the new full-coverage G-suit, we expect[...Click Below to Read More]

Decompression Illness in Aviation

Before English chemist, William Henry, took his own life in 1836, he discovered a simple physics law to explain how gas behaves in solution. This gas law, now appropriately known as Henry’s Law, together with Boyle’s Law, form the basis of the pathophysiology and treatment for Decompression Illness. Henry’s Law[...Click Below to Read More]

Spatial Disorientation

Spatial disorientation (commonly referred to as Spatial-D) is the inability to determine one’s position, location, and motion relative to their environment. Spatial-D along with G-induced loss of consciousness (G-LOC) are two of the most common causes of fatality from human factors in military aviation. Spatial-D regularly affects pilots in all aircraft, whereas only[...Click Below to Read More]
