Goshawks with SASS.


When an aircraft enters service in Naval Aviation, Naval Air Systems Command The Naval Air Systems Command, or NAVAIR, is the part of the United States Navy which provides materiel support for naval aircraft and airborne weapon systems, such as guided missiles. NAVAIR was established in 1966 as the successor to the Navy's Bureau of Naval Weapons (BuWeps).  (NAVAIR) test organizations gear up to do what they do best. Air Test and Evaluation Squadron (VX) 23 under the Naval Air Warfare Center The Naval Air Warfare Center was a former U.S. Navy military installation located in Warminster, Pennsylvania and Ivyland, Pennsylvania.

The U.S. Navy purchased the grounds to establish this facility from the Brewster Aeronautical Corporation following its bankruptcy in the

 Patuxent River, Md., has finalized flight testing on the Stability Augmented Steering System (SASS) developed for the T-45 Goshawk advanced jet trainer. This modification improves the ground handling of the T-45 during takeoffs and landings under crosswind conditions. The improvement should remove the current crosswind restriction for student solo operation of the Goshawk goshawk: see hawk.

SASS provides active yaw rate feedback to the nose wheel steering system. The SASS computer automatically sends inputs into the nose wheel, in many instances before a pilot even senses the initial oversteer o·ver·steer

"In many ways, the T-45 without SASS feels like you're landing a tail dragger," said Lieutenant Allen Blocker, VX-23 lead test pilot for the T-45 ground handling project. "The airframe is slightly unstable directionally on the ground. In a strong crosswind landing rollout, this can lead to an oversteer that can be exacerbated by pilot-induced oscillations. As a result of input from the fleet, this issue became the number one concern to address on the T-45. When SASS is fully deployed in the Goshawk, a significant impediment in operational training flow and a major safety-of-flight concern will be remedied."
