What does the FAR say about communication between the pilot and the dispatcher?

• A. They must communicate only at designated waypoints.
• B. They must communicate at least once per flight.
• C. 121.99 - The Dispatcher and PIC must be able to communicate throughout the entire route.
• D. Communication is optional unless weather is severe.

Answer: (C)

Two-way communication must be maintained between the dispatcher and the pilot in command for the entire route of flight. FAR 121.99 requires a reliable means for the dispatcher to contact the PIC and for the PIC to contact the dispatcher at all times along the route (en route, and through arrival), so that weather updates, routing changes, delays, and other operational information can be coordinated promptly. This isn’t limited to designated waypoints, isn’t required only once, and isn’t optional; it applies throughout the entire flight.
