Abstract: An escape hatch stay system for an aircraft and methods of using the escape hatch stay system. An escape hatch stay system includes a first stop arm, a second stop arm, and a gas strut. The first stop arm is rotatably coupled to the second stop arm, and the second stop arm is pivotably coupled to the gas strut. The first and second stop arms are lockable to preclude relative movement therebetween to lock the escape hatch in an open position. When the escape hatch is in the open position, the escape hatch may not be closed shut without manual intervention. When the escape hatch is in the open position, a load applicable to push the escape hatch open past the open position is damped by the gas strut.

Abstract: A handle assembly for an escape hatch. A handle assembly for an escape hatch comprises an interior handle and an exterior handle. The interior handle has an interior cam associated therewith and the exterior handle has an exterior cam associated therewith. The interior cam and the exterior cam each have a concave profile surface and a curved profile surface. A middle cam is sandwiched between the interior cam and the exterior cam and has a notched profile. The interior and exterior cams are associated with a tumbler having a flag. The middle cam is associated with an output rod operatively coupled to a second flag. Each of the interior handle and the exterior handle can be successively rotated in a first arc of rotation and a second arc of rotation with one hand. The first and second arcs of rotation are respectively associated with the flag and the second flag.
