Aviation Analysis of San Francisco Runway 28L and PAPI Lights
The Instrument Landing System (ILS) on Runway 28L at San Francisco was out of service during the Asiana crash, requiring a visual approach. Pilots rely on Precision Approach Path Indicator (PAPI) lights to maintain the correct glide path, but data suggests the aircraft was flying too slow and potentially stalled before impact. A minor theory regarding a Class X solar flare affecting instruments is also considered.
