SAN FRANCISCO — The wayward Air Canada pilot who nearly landed on a crowded SFO taxiway earlier this month did not activate his computer guidance system that would have helped guide his airplane onto the appropriate runway and not dozens of feet from a catastrophe, according to a source familiar with the federal investigation.
Preliminary findings in the joint Federal Aviation Administration and National Transportation Safety Board investigation have determined that the pilot — who flew for his carrier again the next day after his aborted July 7 landing — did not activate his Instrument Landing System during his visual approach, the source said. The Wall Street Journal, citing two unnamed sources familiar with the investigation, also reported Air Canada flight 759 attempted to land manually with no back-up.
In what experts have called a near-disaster, the Airbus 320 passed over two fully loaded airplanes on the taxiway, as close as 51 feet to one, according to flight data information analyzed by this newspaper, before finally climbing to abort the landing and traveling over two more aircraft. The NTSB and FAA have interviewed the Air Canada flight crew and SFO air traffic controllers.
With the clear weather that night, retired United Airlines pilot Ross Aimer said that, based on air traffic audio, the Air Canada pilot was approved for a Flight Management System (FMS) visual to Runway 28-Right, which would not require him to use his computer guidance system [the FMS visual didn't require him to use his computer guidance system?

Aimer said most pilots don’t use the guidance equipment under those conditions and that type of approach.
