During arming, which doors must be armed and crosschecked?

• A. 1L and 1R
• B. 2L and 2R
• C. 3L and 3R
• D. All doors

Answer: (A)

Arming a door means setting its escape slide to deploy and verifying that the door’s armed status is confirmed. On this 737-700, the doors that must be armed and crosschecked are the two forward passenger entry doors, the ones at the front left and front right. These are the primary evacuation points, so their slides must be ready and their status checked by the crew. The other doors (such as overwing or aft doors) are not part of this arming step in this configuration because they either don’t carry slides or their arming procedure isn’t performed in the same preflight crosscheck. So, the standard arming/crosschecking focus is on the two forward doors.
