During an aircraft incident, what information is critical for ARFF personnel to relay to dispatch?

The critical information that ARFF personnel must relay to dispatch during an aircraft incident includes the location, type of aircraft, and the nature of the emergency. This data is vital because it allows dispatch to understand the specific circumstances of the incident and coordinate an appropriate response.

The location is essential to ensure that emergency units can reach the scene quickly and effectively. The type of aircraft provides important details regarding its size, fuel capacity, and potential hazards, which can significantly influence the tactics used by emergency responders. Lastly, the nature of the emergency—whether it's a fire, fuel leak, or structural failure—helps dispatch assess the situation and deploy the necessary resources, such as specialized equipment and personnel trained for that particular type of incident.

While the number of passengers, flight schedules, and weather conditions can provide additional context, they are secondary to the immediate and pertinent information that directly affects the safety and response strategies in an emergency situation.
