When diverting, when do we communicate with dispatch?

• A. At the end of the flight.
• B. When possible.
• C. Upon arrival at the diversion airport.
• D. As soon as practical.

Answer: (D)

When a diversion becomes necessary, the priority is to inform dispatch as soon as practical so they can support you and adjust the plan. Report promptly after you determine the need, including your current position and altitude, remaining fuel, the diversion airport you’re targeting, your estimated time of arrival, and the new plan or alternatives. Dispatch uses that information to replan routes, coordinate weather and NOTAM updates, arrange support, and keep other parts of operations informed.

Waiting until the end of the flight or only when you reach the diversion airport breaks the chain of situational awareness and can hinder fuel planning and routing decisions. “As soon as practical” emphasizes getting the critical information to dispatch quickly while still maintaining safe operation.
