Aerospace physiology training at Travis AFB U.S. Air Force Logo Sept. 16, 2025 Aerospace physiology training at Travis AFB U.S. Air Force Capt. Justin Kong, 312th Airlift Squadron pilot, operates a Hypoxia Familiarization Trainer (HFT) while wearing a quick don mask during aerospace physiology training at Travis Air Force Base, California, Sept. 9, 2025. An HFT is a sophisticated training device used to teach aircrew how to recognize and respond to the symptoms of oxygen deprivation in daylight and lowlight conditions.

Justin Kong, left, 312th Airlift Squadron pilot, operates a Hypoxia Familiarization Trainer (HFT) while wearing a quick don mask as Staff Sgt. Yomira Ramirez-Martinez, 60th Operations Support Squadron wing physiology noncommissioned officer in charge, engages the oxygen dump valve on a Reduced Oxygen Breathing Device (ROBD) during aerospace physiology training at Travis Air Force Base, California, Sept. 9, 2025. During aerospace physiology training, the ROBD and HFT simulate oxygen levels at different altitudes using a quick don mask, helping aircrew recognize the symptoms of oxygen deprivation in daylight and lowlight conditions.

Jordan Skillman, 60th Air Mobility Wing Safety office flight safety officer, checks for cyanosis in his fingertips during aerospace physiology training at Travis Air Force Base, California, Sept. 9, 2025. Cyanosis, or bluing of the fingertips, is a symptom of hypoxia which aerospace physiology training helps aircrew recognize to correct for quickly by reconnecting to oxygen.
