The loss of Bering Air Flight 445 on the Unalakleet to Nome hop made two things painfully clear to pilots who fly Alaska for a living. First, modern surveillance data can help investigators reconstruct a flight quickly. Second, real time surveillance for search and rescue in much of rural Alaska is still dependent on patchwork infrastructure and archived feeds rather than continuous ground coverage that controllers or rescuers can rely on in an emergency.
From an operational perspective ADS-B is a simple concept. An aircraft that is equipped with ADS-B Out broadcasts its GPS-derived position and basic flight data, and ground stations or satellites receive those broadcasts. Controllers and public tracking services display that traffic for situational awareness. But the utility of ADS-B is only as good as where someone is listening. Large swaths of Alaska have historically lacked consistent ground station coverage, which was one of the reasons Congress directed the FAA to deliver ADS-B coverage to Alaska by a set deadline and to waive traditional benefit cost constraints for that work. In practice the state still relies on a mix of FAA ground sites, community receivers, archived ADS-B records and, where available, space-based providers.
The NTSB preliminary reconstruction relied in part on archived FAA ADS-B data to piece together Flight 445’s profile and last moments. That fact shows two opposite truths at once. Archived ADS-B and onboard avionics can give investigators a precise picture after the fact. But for front-line search and rescue the problem is whether real time, reliable position data exists to narrow initial search boxes and vector assets while lifesaving minutes tick by. News reports from the initial search noted authorities were working to determine the aircraft’s last known coordinates before resources could be concentrated.
Space-based ADS-B providers can and do fill gaps outbound from ground networks because they receive 1090ES transmissions from equipped aircraft everywhere the satellite constellation can see them. That capability means ADS-B equipped aircraft can be tracked over ocean and polar regions where ground stations do not reach. But space-based feeds only help if the airframe is equipped and set to broadcast on a compatible link. They are not a substitute for robust local surveillance, and they do not help non‑ADS-B aircraft.
What this means for pilots and operators flying Alaska regularly is practical and unglamorous. If you run a Part 135 operation or fly single engine IFR routes over water, assume that immediate, continuous ground surveillance may not be available along every mile of your route. Make conservative dispatch choices accordingly. That includes prudent weight and cargo planning in forecast icing, strict adherence to speeds that preserve maneuver margin in the event of ice accretion, and carriage of independent, satellite capable trackers and emergency beacons. For operators, expedited equipage with 1090ES ADS-B Out and provision of ADS-B In capable cockpit displays where appropriate raises the chances that your aircraft will be seen by both terrestrial and space-based receivers. The FAA has language in the recent reauthorization to encourage and incentivize Part 135 equipage in Alaska. Turning that language into firm dates, funding and enforcement will matter for safety.
On the system side the fix is also straightforward though difficult. The aviation community has been calling for a Minimum Operational Network of additional ADS-B ground stations to close coverage holes along major Alaskan routes. That proposal has been supported by industry groups for years and is reflected in congressional direction. Rapidly deploying more ground sites, pairing them with space-based data streams for redundancy, and ensuring SAR agencies have direct, low-latency access to those feeds will shrink search areas and buy time in future accidents. The FAA, ANSPs and industry should prioritize connecting those data feeds to the agencies that task rescue assets so archived playback is not the only source when minutes count.
Recommendations for immediate steps pilots and operators can take
- Treat ADS-B Out as necessary equipment when operating over ocean or remote ice. Make 1090ES equipage a policy for single engine and Part 135 operations in Alaska rather than optional.
- Carry independent, satellite-based position trackers and make sure ELTs are maintained and registered. Iridium trackers that provide live position streaming add a second, independent path for locating a downed aircraft.
- Update dispatch and load planning to explicitly account for icing penalties and reduced climb and maneuver margins when weight limits are approached. That is a flight operations control fix that does not wait on infrastructure changes.
- Advocate within your operator and local aviation community for shared access to space-based ADS-B feeds and for faster FAA deployment of additional ground stations under the existing legislative mandate. Shared data access between ATC, SAR and local operators shortens the time from overdue call to search vector.
The tragic Bering Air accident will be parsed at length by the NTSB and industry. For pilots who fly those remote routes daily the takeaway is immediate. Technology can and does help. But coverage is not uniform and relying on a single surveillance pathway is a recipe for delayed response. Push for the Minimum Operational Network in Alaska, carry a satellite contingency, and run your operation with the conservative margins that these skies demand. If we get those basics right, the next time an aircraft goes missing crews will have a real time picture to act on instead of a reconstruction to study after the fact.
