Which of the following is a minimum crew position on the 767-400 ER (764)?

• A. IL, 1R, 2L, 2R
• B. IL, 1R, 2L, 2R, 3Li, 3ri
• C. IL, 1L, 2R, 3Li, 3Ri
• D. IL, 1R, 2L, 2R, 3Li, 3ri, 4R

Answer: (D)

The key idea is that the minimum crew must cover every cabin zone and include a supervisor to coordinate operations, while keeping the flight deck staffed. In this configuration, an In-Flight Lead (IL) is present to oversee cabin safety and coordination, and a crew member in the 1R seat supports the flight deck. The cabin is then staffed across all major zones: forward (2L, 2R), mid (3Li, 3Ri), and aft (4R). This distribution ensures timely service, passenger assistance, and a clear line of supervision in any situation. Other rosters either miss a cabin zone (leaving some area unstaffed) or omit the supervisor role, which would reduce safety coordination and service effectiveness. This combination uniquely provides complete zone coverage with the necessary supervisory link, making it the minimum viable crew for the 767-400ER.
