Exterior handle position indicator for aircraft escape hatch

1. An escape hatch for an aircraft, comprising:

a door body having an exterior side and an interior side opposite the exterior side;

an exterior handle movably connected to the door body, the exterior handle rotatable between a stowed position, in which the exterior handle is recessed within an opening of the door body, and an unstowed position, the exterior handle being accessible from the exterior side ofthe door body to open a door comprising the door body; and

wherein the door body defines an aperture through which a visual indicator is connected to the door body and visible from the interior side of the door body only when the exterior handle is in the stowed position; and

wherein any component of the visual indicator is not visible from the interior side of the door body when the exterior handle is in the unstowed position; and

wherein the visual indicator is selectively moveable between a retained position and an unretained position, the retained position to secure the exterior handle in the stowed position; and

wherein the doorbodydefinesa n a pertu re through which a latch is visible from the interior side of the door body only when the visual indicator is in the retained position, wherein the latch latches the exterior handle into the stowed position.

2. The escape hatch of claim 1 , wherein the visual indicator is visible from the interior side of the door body only when in the retained position.

3. The escape hatch of claim 1 , wherein the visual indicator is biased toward the retained position.

4. The escape hatch of claim 3 , comprising a biasing member biasing the visual indicator to rotate the visual indicator in a first rotational direction, about an axis, past the retained position, and when the exterior handle is in the stowed position, the latch is prevented from rotating past the retained position to secure the exterior handle in the stowed position, and upon rotation of the visual indicator in a second rotational direction about the axis, opposite the first rotational direction, the exterior handle is movable to an unstowed position, wherein the latch latches the exterior handle into the stowed position.

5. The escape hatch of claim 1 , wherein the visual indicator is rotatably connected to the door body.

6. The escape hatch of claim 1 , wherein the exterior handle is rotatably connected to the door body.

7. An aircraft comprising the escape hatch of claim 1 .

8. A door fora n aircraft, comprising:

a door body having an exterior side and an interior side opposite the exterior side;

an exterior handle movably connected to the door body, the exterior handle rotatable between a stowed position, in which the exterior handle is recessed within an opening of the door body, and an unstowed position, the exterior handle being accessible from the exterior side ofthe door body to open the door;

a hook connected to the door body and selectively moveable between a retained position and an unretained position, the retained position to secure the exterior handle in the stowed position; and

a visual indicator mechanically coupled to the hook,

wherein the door body defines an aperture through which the visual indicator is visible from the interior side of the door body only when the hook is in the retained position;

and wherein any component of the visual indicator is not visible from the interior side of the door body when the hook is in the unretained position; and

wherein the hook is rotatably connected to the door body; and

wherein the door further comprises a biasing member biasing the hook to rotate the hook in a first rotational direction, about an axis, past the retained position, and when the exterior handle is in the stowed position, a latch is prevented from rotating past the retained position to secure the exterior handle in the stowed position, and upon rotation of the hook in a second rotational direction about the axis, opposite the first rotational direction, the exterior handle is movable to an unstowed position, wherein the latch latches the exterior handle into the stowed position.

9. The door of claim 8 , wherein the hook is biased toward the retained position.

10. The door of claim 8 , wherein the visual indicator is rotatably fixed to the hook.

11. The door of claim 8 , wherein the exterior handle is rotatably connected to the door body.

12. An aircraft comprising the door of claim 8 .
