How should a dispatcher respond to a significant change in weather during a flight?

The appropriate response for a dispatcher when there is a significant change in weather during a flight is to inform the flight crew immediately with updates. This is crucial because the safety of the aircraft and those on board is the top priority. Dispatchers have access to real-time weather data and can provide the crew with vital information that may affect their flight path, landing approach, or overall safety.

Keeping the flight crew informed allows them to make informed decisions regarding rerouting, altitude adjustments, or potential diversions to alternative airports if necessary. Quick and accurate communication ensures that the crew can react to changing conditions effectively and maintain safety throughout the flight.

In contrast, ignoring the weather changes could lead to dangerous situations, while waiting for the flight crew to report back could delay crucial responses to imminent threats. Similarly, rescheduling the landing without informing the crew fails to provide them with important situational awareness, which is critical in managing safe and efficient flight operations.
