New Navy flight mask could prep aviators to avoid blacking out mid-flight - Breaking Defense

The Navy recently demonstrated a new training device designed to help prepare its pilots for potential emergencies in the air by having them feel the effects of oxygen deprivation while safely on the ground, the latest tool in the service’s years-long struggle with the phenomena known as physiological episodes.

The “Mask on Breathing Device,” which the service demonstrated for senior brass on July 7, lets pilots feel the symptoms that could occur during flight that would lead to a physiological episode, ranging from hypoxia to hyperventilation and “air hunger.” The service has delivered 10 devices to date and plans to install 35 throughout the fleet’s training centers.
