Cobham has completed internal development of an Exhalation Gas Sensor for the US Air Force (USAF) School of Aerospace Medicine, the company announced on 18 September.

The exhalation sensor block, developed in support of the Aircrew Mounted Physiologic Sensing System (AMPSS 2.6) programme, will be delivered to the USAF by the end of this month, completing a two part breathing sensor system which includes an inhalation sensor block that was delivered in June.

Together the two blocks comprise a pilot-mounted sensor system designed to capture in-flight, real-time oxygen system, cockpit environmental, and pilot physiological data to help determine root cause of physiological events that continue to effect pilot safety and performance.

Understanding root cause is the first critical step towards designing a solution that will be able to predict and prevent the onset of hypoxia-like symptoms. The next phase of development will include a warning feature that will alert the pilot to take manual corrective action. A future state system will include a mitigation capability that automatically adjusts breathing regulator output based on data the sensors are providing. Ultimately, the gas sensors will be integrated into a next generation, complete life support system that will seamlessly predict and pre-empt the onset of hypoxia-like symptoms.

The inhalation sensor block is located on the end of the pilot mask breathing hose and is attached to a chest mounted breathing regulator or integrated terminal block. The exhalation sensor is positioned at the end of second hose attached to the mask exhalation port and can sit inside a vest pocket so as not to impede the pilot’s field of regard.
