FAA Part 139 gives an ARFF crew three minutes or less to reach the midpoint of the farthest runway. That clock starts the instant an emergency is declared, and a surprising share of it can be lost before a single vehicle moves. Most of the lost time is in the notification: a call relayed by hand, a radio message repeated, an agency that hears about the emergency a beat behind everyone else.
Cutting that time is the fastest way to improve ARFF performance, because it gives back seconds the crew can spend rolling rather than waiting. Westnet's aircraft emergency systems are built to take those seconds out of the notification process, and our guide to airport alerting systems covers how the full platform fits together.
A legacy crash phone process is a series of manual steps, and each one costs time. Someone places the call, waits for an answer, relays the details, and repeats the process for the next agency. Add a busy controller, a noisy line, or a missed handset, and the gap between declaration and turnout grows. The failure modes are spelled out in our look at crash phone systems, but the short version is that a manual chain cannot move as fast as the standard now expects.
Westnet's patented AES replaces that chain with a single declaration. The moment an emergency is entered, the system delivers synchronized audio, visual, and voice alerts to ARFF stations, airport operations, dispatch, and mutual-aid partners in the same second, with no confirmation step and no repeated calls.
ARFF crews start moving sooner because the alert reaches them directly and carries the incident details with it. Everyone else starts from the same information at the same moment, which is the foundation of the broader coordination gains covered in multi-agency coordination.
An ARFF team has to be reachable at all times, including during a power disruption or an equipment fault. AES runs on multiple communication paths with backup power and fault monitoring that flags a problem before it affects a response. If the primary path drops, the alert moves over a backup automatically, so a single point of failure does not stand between dispatch and the crew.
Speed only helps if the information is right. AES delivers automated voice prompts and incident details, the type of emergency, the staging location, and any immediate hazards, at the moment of activation. Crews reach the apparatus bay already briefed instead of trading clarifying calls, and outside agencies receive the same details so their staging lines up with ARFF.
FAA inspections expect reliable communication and accurate response-time records. AES logs every activation automatically, with timestamps for the initial alert, acknowledgments, and response progress. That record lets an airport verify its performance against FAA Part 139 and gives safety officers a clear timeline for after-action review rather than a reconstruction from memory.
Airports running AES report faster alerts, clearer communication, and a more predictable response, and the gains hold up in real incidents, as in our account of rapid aircraft emergency response at an Air Force base.
When that performance becomes a capital request, the case for aircraft emergency system investment sets the response-time gains alongside ROI, AIP funding, and risk reduction for the airport's decision-makers. To see how AES would map to your runways and stations, request a quote for your operation.
