How many O2 masks are in the OFAR and OFCR respectively?

• A. 6 in OFAR; 3 in OFCR
• B. 4 in OFAR; 2 in OFCR
• C. 8 in OFAR; 4 in OFCR
• D. 5 in OFAR; 5 in OFCR

Answer: (A)

The test is about how oxygen masks are distributed in the crew rest areas. In Boeing 787s, each rest area has a mask count that matches the maximum number of occupants it can hold, so everyone has quick access in an emergency. The OFAR rest area is configured for six occupants, so it has six masks, while the OFCR rest area is configured for three occupants, so it has three masks. This setup ensures immediate, individual access to oxygen for everyone in those zones without depending on others.
