What is the base of operation where a crewmember is assigned?

• A. Ferry
• B. Domicile
• C. Per Diem
• D. Layover

Answer: (B)

The base of operation is the crewmember’s domicile—the home base where their duties are scheduled, payroll is issued, and training or onboarding is coordinated. This location defines where a crew member is considered to be stationed for operational purposes, even when they’re on trips that take them away from home during layovers. A layover is simply the time spent in another city between flight legs, not the base itself. A ferry is a repositioning flight used to move aircraft or crews, again not the home base, and Per Diem is just the daily allowance provided for expenses while working away from home. Because a crewmember’s domicile serves as the official base tied to assignment and administration, it is the correct answer.
