What is the final action required to release an O2 compartment hatch after pressing the latch?

Explanation:
The action tested is about how a two-step latch release works on a hatch. After you press the latch release, you must rotate the handle a full 180 degrees counterclockwise to disengage the locking cams and clear the strike. This rotary motion uncouples the internal locking pawls so the hatch can swing open or slide out without being held by the latch components. The 180-degree turn ensures the latch isn’t just unlocked superficially but is fully released, providing a secure, deliberate release that won’t reseat with vibration or movement. Rotating 90 degrees wouldn’t fully disengage the cams, so the hatch would stay secured. Pushing inward and sliding outward or pulling upward alone doesn’t interact with the rotary locking mechanism the same way and wouldn’t reliably release the hatch.
