How should dispatch respond to weather deviations en route after release?

• A. Increase speed to outrun weather without changes.
• B. Recalculate fuel and route, consider a re-release or amendment, and inform crew and ATC of changes and expected contingencies.
• C. Do nothing; continue as planned.
• D. Only inform the captain; no re-planning needed.

Answer: (B)

When weather deviations occur en route after release, the dispatcher must reassess the flight plan and communicate updates. This means recalculating fuel requirements and the route based on the new weather picture, considering whether a re-release or amended release is needed, and informing the crew and ATC of changes and the expected contingencies. Why this is best: weather can change fuel consumption, alternate options, and required routing. Recomputing fuel ensures adequate reserves for the actual path, holds, diversions, or contingencies. Re-evaluating the route and issuing a re-release or amendment keeps the flight plan current and compliant, and sharing the updated plan with the crew and ATC maintains coordination and situational awareness, reducing risk. Pushing speed to outrun weather ignores fuel and performance limits and can create new hazards. Doing nothing fails to address the evolving weather and potential changes in time, fuel, or routing. Informing only the captain without updating the plan or coordinating with ATC leaves important parties out of the loop and can lead to miscommunication and unsafe decisions.
