ADS‑B dramatically reduces search areas

Max talks with Cyriel Kronenberg, Vice President of Airports and Air Traffic Management at uAvionix and a volunteer with the Civil Air Patrol’s National Radar Analysis Team (NRAT), about one of aviation’s most overlooked safety questions: if you survive a crash, how quickly will you be found?

How Long Searches TakeCyriel explains that while ADS-B has shortened search times, the reality is sobering. Without a flight plan, overdue aircraft may not even be reported missing for hours. Average search times have historically stretched from 18 hours with a VFR flight plan to more than 60 hours with no plan at all. Even today, two to three hours is considered fast for locating a downed aircraft.

ELTs: The Critical DifferenceCyriel stresses the enormous difference between old 121.5 MHz ELTs and modern 406 MHz beacons. The older units provide only a vague signal and are prone to false alarms, often ignored. A properly registered 406 beacon, by contrast, transmits GPS coordinates via satellite, dramatically reducing search times. But here’s the catch: as many as half are mis-registered, with outdated or missing phone numbers. That makes even the best ELT nearly useless until rescuers conduct a blind search.

Flight Plans, Contacts, and ADS-BFiling a flight plan helps, but only if searchers can reach someone who knows your intended route. Cyriel urges pilots to list an emergency contact not on the aircraft in the remarks section—ideally a spouse, friend, or FBO. While apps like ForeFlight allow pilots to enter contact details, those aren’t passed to the FAA. ADS-B provides an even bigger safety net: an aircraft with ADS-B out can usually be pinpointed within yards, while non-equipped aircraft may take days to locate.

Survival LessonsCyriel shares personal changes he’s made after years of analyzing accidents. He always keeps his cell phone in his pocket so it won’t be lost in a violent crash, carries a handheld transceiver tuned to 121.5 MHz, and wears or packs high-visibility gear. He emphasizes staying with the aircraft, since wreckage is easier to spot than a single person. Route planning also matters—flying near highways or populated areas at night increases survivability compared to wilderness routes.

Behind the Scenes of NRATMax and Cyriel dive into how NRAT works with the Air Force Rescue Coordination Center (AFRCC). Using radar, ADS-B, and even cell-phone forensics, the team helps determine whether an incident is a false alarm, an accident with no survivors, or a mission where lives can be saved. They coordinate directly with controllers and search crews, sometimes correcting errors in coordinate formats that would otherwise send helicopters to the wrong location.

Success Stories and ScaleIn 2024, AFRCC handled nearly 500 aviation missions, with over 200 lives saved. Civil Air Patrol was involved in more than 300 of those missions, while NRAT contributed to 71 cases—directly responsible for dozens of finds and 10 documented saves. Cyriel recalls a dramatic case in Montana where local ADS-B receivers installed by uAvionix employees helped locate a couple who survived a crash into icy water; thanks to quick coordination, a helicopter pulled them out within 20 minutes.

Key Takeaways for PilotsCyriel closes with a checklist:

• Make sure your ELT is registered correctly.
• Consider adding a personal locator beacon.
• Use ADS-B out whenever possible.
• File a flight plan and put a reachable emergency contact in remarks.
• Carry your cell phone and handheld radio on your person.
• Stay with the aircraft if you go down.

Max underscores the theme: nobody takes off expecting to crash, but hundreds of missions each year prove it happens. With preparation, you can improve your odds not just of surviving the impact, but of being found in time.
