United Airlines Primary Aircraft – B737-700 (73G) Practice Test

In a crew of four or more, cross-check duties are assigned to provide an independent verification of an exit’s status. FA1 is responsible for cross-checking the forward left exit. This means FA1 visually verifies that the door status and related safety indicators match what was set by the crew member responsible for that exit, ensuring the door is properly armed/disarmed and the area is ready for use if needed. The purpose is to add a second layer of assurance so a mis-set door doesn’t go unnoticed.

This cross-check is not performed for the other front exit in this scenario, and it isn’t skipped in a four-plus crew setup—the forward left exit is the one designated for FA1’s cross-check to maintain clear, redundant safety verification.
