Spatial disorientation (SD) is a false perception of position, motion or attitude by the pilots, and the largest risk factor for fatal accidents. Prevention of SD is difficult. Early realization and withdrawal from SD using instrument flight is the best way to prevent accidents. To prevent accidents due to SD, aircraft’s systems have been developed, and SD training have been conducted. Terrain Awareness and Warning System (TAWS) provides pilots with visual and auditory warning. Automated Ground Collision Avoidance System (Auto GCAS) recovers flight attitude automatically when aircraft goes near into the ground. Spatial Orientation Retention Device (SORD) is multi-sensory warning system. Tactile Situation Awareness System (TSAS) gives vibration to the pilots to indicate pilot’s posture. Three Dimensional Landing Zone (3D-LZ) System projects view of landing zone to the cockpit even in bad weather. In this study, we collected information related to SD training among 21 military forces belong 17 countries. SD training usually includes lecture and experience learning. Pilots receive initial training and periodic training in 17/21 forces. Average frequency was 4 years (range: 6 months to 6 years). Japan Air Self-Defense Force has not conducted periodic SD training. The way of experience with SD is use of simulator similarly JASDF or in-flight demonstration. The simulator training is lower cost and safer than the in-flight training. To maintain and develop aircraft’s systems and SD training is continuously necessary.

Flight line personnel are exposed to exhaust emissions from aircraft engine during line maintenance work. The exhaust emissions include volatile monocarboxylic acids (VMCAs) that can cause sensory irritation of eyes, nose and throat. The purpose of our study was to determine levels of VMCAs in the exhaust emissions from F-15 fighter aircraft and T-4 JASDF jet trainer. The VMCAs in the exhaust emissions were collected by using a honeycomb diffusion denuder device, and analyzed by gas chromatography. Formic acid and acetic acid were detected in both F-15 and T-4 aircrafts. Higher levels of formic acid (163 ppb) and acetic acid (104 ppb) were detected in T-4, although those were under irritation threshold and the exposure limitations. The present results suggested that health risk of flight line personnel to those volatile acids were limited.

Gravity-induced loss of consciousness (G-LOC) is a major threat to fighter pilots and may result in fatal accidents. High +Gz (head-to-foot direction) acceleration force induces cerebral blood loss and results in gray-out, black out, and G-LOC. Countermeasures to avoid G-LOC include anti-G strain maneuver, anti-G suits, and pressure breathing for G, etc. They effectively decrease G-LOC incident, but have not eradicated it. Objective detection of G-LOC related symptoms is the prerequisite. In spite of many G-protective measures, G-LOC monitoring system has yet to be developed. Technologies for non-contact monitoring or motion capture have ventured into health care market. Real time physiological sensing for heart rate, body temperature, respiratory rate, etc, is used to medical, health care, physical fitness and sports area. Those advanced technologies might have potential for future G-LOC monitoring. This article reviews current status and future of countermeasures for G-LOC, and related technologies.
