Which parts of 121 require dispatchers?

• A. Domestic and Flag
• B. International and Domestic
• C. Cargo and Passenger
• D. VFR and IFR

Answer: (A)

Under Part 121, flight dispatchers are required for the scheduled airline operations that are domestic (within the United States) and flag (international) services. A dispatcher provides essential flight planning and operational control, coordinating weather analysis, route selection, fuel calculations, alternate airports, performance data, and regulatory compliance, and staying in touch with the flight crew to keep the operation safe and efficient. The idea is that these two categories—domestic and flag—cover the main scheduled operations that necessitate this level of centralized planning and monitoring. The other options don’t reflect the regulatory split used for dispatch requirements: international flights are encompassed in flag operations, and cargo versus passenger or VFR versus IFR describes other aspects (operation type or flight rules) rather than where dispatchers are mandated.
