Aircrew of modern tactical aircraft are exposed to extreme acceleration ("G" loads) during air combat maneuvering. With a constantly improving performance envelope, aircraft can also fly at higher altitudes. Specialized life support systems are required in order to minimize a pilot losing consciousness from prolonged acceleration exposure or from low oxygen levels encountered during in-flight cockpit decompression. The protective systems and garments are central in both protecting the pilot and in maximizing human performance under these adverse conditions.

Contrail Consulting Services has a rich history in the design, test, and evaluation of life support hardware. Past project involvements includes:

Protective Systems
  • Development of Sustained Tolerance for INcreased +Gz (STING) specifications for implementation into the Canadian Forces F/A-18 Hornet aircraft. STING system is currently licenced for distribution with GENTEX corporation and the lower pressure garment (G-suit) is operational in CF-18 Hornet aircraft. Modifications to the STING G-suit have been made for delivery for United States Navy in-flight evaluations and acceptance tests
  • Research support in the evaluation of protective garments used for high altitude protection for next generation U.S. Navy tactical aircraft. Involved in the test and evaluation of various garments for get-me-down support following explosive decompression at 60,000 and 72,000 feet (NATLISS Program).
  • Development of stick force feedback simulation system software in human centrifuge assessments
