Abstract: A transport unit particularly adapted to contain an injured person in a manner that the person can be moved with relative comfort and safety. There is a rigid containing structure having inflatable cushions positioned therein and arranged to fit the contours of a person's body. The person is placed in the container, and a lid of the container is placed over the person, with the cushions then being inflated to firmly, yet gently, hold the person in place.

Abstract: A system for warning the pilot when the aircraft has reached a high yaw condition. A differential in pressure or angle of attack between the port and starboard sides of the aircraft is measured and converted into a measured sideslip angle. If the measured sideslip angle exceeds a predetermined maximum acceptable sideslip angle, a warning device, such as a rudder pedal shaker, is activated. The maximum acceptable sideslip angle is determined as a function of the ability of the aircraft flight controls to counteract a rolling moment generated by the yaw condition.
