Which system must be armed when the crew rest is occupied on the 767?

• A. Crew Rest low Airflow System
• B. Lower Lobe light system
• C. Overhead PA system
• D. Ground de-icing system

Answer: (A)

Controlled ventilation for an occupied crew rest is the idea being tested. When the crew rest is in use, arming the dedicated low airflow mode ensures the rest area gets properly conditioned air with minimal noise and drafts, keeping the space comfortable and maintaining adequate air exchange without being overwhelmed by the main cabin flow. The other systems listed serve lighting, public addressing, or external de-icing and aren’t part of maintaining the crew rest environment in flight, so they aren’t required to be armed for occupancy.
