What is the first step when arming or disarming any 777 door?

• A. Lift the protective cover
• B. Push the door handle
• C. Turn the wheel
• D. Pull the door latch

Answer: (A)

The first action is to lift the protective cover to access the door’s arming/disarming control. That cover acts as a safeguard, hiding the actual control so it isn’t bumped or triggered accidentally. By raising it, you deliberately reveal the mechanism you need to operate to arm or disarm the door. Once the cover is up, you can then engage the proper control to set the door to the desired mode. The other steps—pushing the handle, turning a wheel, or pulling a latch—are actions that come after you’ve accessed the control and are part of the physical operation of the door, not the initial step to enable arming or disarming.
