What is the process for handling an urgent weather reroute close to departure?

• A. Notify dispatch, re-file the flight plan with updated routing, and brief the crew on new minima and expectations.
• B. Only notify ATC and delay re-planning.
• C. Ignore the reroute if time is tight.
• D. Change aircraft without informing crew.

Answer: (A)

When a weather reroute becomes urgent near departure, rapid, coordinated action is essential. The best practice is to involve dispatch immediately, re-file the flight plan with the updated routing, and brief the crew on the new minima and expectations. Dispatch has the authority and resources to reassess fuel requirements, weather constraints, and alternate options, and they manage the operational risk and paperwork needed for a safe departure. Re-filing the flight plan ensures the official record, ATC communications, and navigation databases reflect the new route, so everyone operates with the same current plan. Briefing the crew on the revised routing, anticipated weather, minima, and expected procedures or contingencies ensures the flight deck can execute the reroute safely and confidently. This approach maintains safety, compliance, and smooth operation as the flight transitions to the new path. Choices that skip dispatch coordination and formal plan updates, ignore the reroute, or involve changing aircraft without crew notification fail to address the essential need for timely, clear communication and documented planning.
