Asiana Airlines flight experiences low-altitude alert near San Francisco airport

The Aviation Herald reported: “According to ADS-B data the aircraft was descending through about 650 feet AGL (325 feet according to transponder measuring to standard pressure corrected for actual ambient pressure) when the aircraft should have been at 1000 feet 3.05nm before the runway threshold. ”

Seoul-San Francisco is a busy route with several airlines offering services. According to data by Cirium, an aviation analytics company, there are more than 135 flights from Seoul to San Francisco in February. United Airlines, Korean Air, and Air Premia also operate this route.

Pilots are trained for missed approaches with standard procedures in place to execute these maneuvers safely. A missed approach does not necessarily reflect pilot error and is considered part of standard procedure to ensure safety.

Once it is decided that an approach is no longer safe, the aircraft must climb back to a designated altitude. The pilot increases engine power retracts the landing gear and establishes a safe climb. After going around following specific instructions from air traffic control may involve joining a holding pattern or being vectored for another approach.

Similar incidents have occurred in the past involving other airlines. In June 2024 a Southwest Airlines aircraft came close to ground level while miles away from Oklahoma City’s Will Rogers World Airport triggering a low-altitude warning prompting ATC intervention. The Boeing 737-800 descended to around500feet while still nine miles out but returned for successful landing after going- around.
