The FAA issued a recommendation on July 28 to the flight crew of non-U.S. airlines flying into San Francisco International Airport (SFO) to back up a visual arrival by using a GPS approach normally stored in the aircraft’s flight management system (FMS). The onboard approaches can generate a virtual glideslope during visual approaches regardless of the status of ground-based electronics. The agency was inspired to make the recommendation by the July 6 crash of an Asiana Airlines Boeing 777 at SFO during a visual approach while the glideslope for the landing runway was inoperative. The recommendation is expected to remain in effect until the glideslope on Runway 28L at SFO returns to service later this month.
