Plane lands itself after cabin pressure failure in a world-first real emergency, when a Beechcraft Super King Air 200 used Garmin’s Autoland system to complete an entire sequence from climb through loss of pressurisation to landing, braking and engine shutdown with no passenger on board.
Plane lands itself after cabin pressure failure: What happened in the air
Plane lands itself after cabin pressure failure occurred as the Buffalo River Aviation-operated King Air climbed through 23,000 feet from Aspen when cabin pressurisation failed, prompting both pilots to don oxygen masks and allowing Autoland to engage automatically and select Rocky Mountain Metropolitan Airport (KBJC) as the safest option.
The system announced “pilot incapacitation… emergency autoland in less than one minute on runway 3-0 right,” then flew through instrument conditions and icing, navigated mountainous terrain, lined up on Runway 30R, landed, braked and shut down the engines entirely on its own while pilots stood by to intervene if needed.
Garmin Autoland’s historic first in real-world use
Garmin confirmed this as the first full real-world emergency use of Autoland from airborne emergency detection to complete stop, on a King Air 200 equipped with G1000 NXi avionics and recent Autoland upgrades.
Installed on roughly 1,700 aircraft, the system can activate automatically after events like pressure loss or be triggered manually, taking over radio calls, navigation, approach and rollout to support scenarios where crew may be incapacitated or overwhelmed.
Safety decisions, FAA review and next steps
Buffalo River Aviation praised the crew for letting the automation run uninterrupted, emphasising that prioritising life and safety meant trusting the certified system while monitoring in the cockpit.
The US Federal Aviation Administration has opened an investigation, even as the aircraft resumed normal operations the next day, and Garmin has called the incident a major safety milestone for operational autonomy in business aviation.
