Workflow

An aircraft fitted with Garmin Autoland. Garmin says more than 1,700 are equipped. A rapid, uncommanded loss of pressurization that pushed cabin altitude past the system's automatic trigger. A crew that decided to let the automatic sequence run to touchdown rather than take over.

Human oversight

Not assessed

Relation to AI

Autoland engaged itself when cabin altitude exceeded the limit. It declared the emergency to controllers with automated “pilot incapacitation” broadcasts. It flew the descent, approach and landing. The pilots elected to leave it engaged rather than take over. So the landing is the system's work. But the counterfactual, that they could not have landed, is not established. Garmin, the FAA and the operator all call it an automated system. None calls it AI. It is here because the OECD Monitor lists it as an AI system. The Register describes it choosing landing sites from runway length, distance and fuel range.

Follow-up

Conditions for replication

The aircraft remains airworthy. Autoland is a fail-safe for a working aircraft whose pilot cannot fly it, in the words of the journalist CBS quoted. A suitable airport is in range. The Register describes selection by runway length, distance and fuel range. Controllers and ground services act on the automated broadcasts, as Broomfield's two fire departments did.

Replication attempts

Not assessed

Later findings

The FAA said it was investigating and the NTSB that it was collecting information to decide whether the event met its criteria; no FAA or NTSB report or other development after December 2025 was found. The aircraft flew on to Oklahoma City the next morning.

Reasons

People: Two pilots who had lost cabin pressure at 23,000 ft were on the ground in Broomfield within about 35 minutes of departure, untreated and uninjured. They were conscious and could have flown the descent themselves. So the benefit is a safe automatic recovery, not a documented life saved. Organizations: Buffalo River Aviation's aircraft “landed safely without incident”, in the airport spokeswoman's words. No damage is reported, and the FAA investigation was still open.

Aviation safety / automatic emergency landing. Charter turboprop operations.

Purpose

Autoland exists to take complete control of an aircraft and land it when the pilot cannot fly. It engages on its own when cabin altitude exceeds a set level. That is what happened here. The two pilots turned out not to be incapacitated, though, and chose to let it finish.
