After reading this article, I still don't understand how the pilot "landed" in the water several miles short of the runway when the radio altimeter still showed 200ft AGL. Someone suggested that both altimeters failed. But when I read the NTSB report, it blamed the "Un(der)qualified" crew instead. Anyone know what's going on here?
Capt. Asoh said that he was making a coupled approach, but because of problems with his pressure altimeter, he was relying on the more accurate radio altimeter for verification of altitude. Capt. Asoh set the radio altimeter to give a light at a decision height of 211 ft (63.3 m). When the light blinked on ... he was nearly in the waters of San Francisco Bay - Richard Silagi
PROBABLE CAUSE: "The improper application of the prescribed procedures to execute an automatic-coupled ILS approach. This deviation from the prescribed procedures was, in part, due to a lack of familiarization and infrequent operation of the installed flight director and autopilot system." - NTSB AAR-70-02
