Which element is typical in a preflight crew briefing before takeoff on the 737-700?

• A. Review emergency procedures only.
• B. Confirm EXIT usage and landing checklists.
• C. Confirm EXIT usage, review emergency procedures, and assign roles for post-event tasks.
• D. Brief the cabin on in-flight service.

Answer: (C)

The main idea here is that a thorough preflight crew briefing on a 737-700 combines three safety-critical elements: knowing which exits will be used and who operates them, reviewing the emergency procedures so all crew members can act quickly and in unison, and assigning roles for tasks that come after an event (post-event tasks) to keep the cabin organized and passengers safe.

Confirming exit usage ensures everyone knows which doors and any overwing exits are designated for evacuation and who is responsible for operating each one. Reviewing emergency procedures makes sure all crew members are familiar with the exact steps for fires, depressurization, evacuations, and medical emergencies, so responses are coordinated rather than improvised. Assigning roles for post-event tasks sets clear responsibilities—who counts passengers, who assists those needing help, who communicates with ground personnel, and who handles securing the cabin after an safety incident. This combination is what you’d typically expect to cover in a preflight briefing.

The other options miss key safety elements: focusing only on emergency procedures omits exit strategy and role assignment; mentioning exit usage with landing checklists ignores the broader safety procedures; and briefing the cabin on in-flight service is not relevant to the preflight safety briefing.
