Interpretation

For the San Antonio International ILS or LOC RWY 31L Amendment 12A procedure, S-ILS 31L decision altitude is 1,136 feet with a height above touchdown of 346 feet, and visibility for all categories is RVR 3,000. With the approach lighting system inoperative, increase visibility for all categories to RVR 5,500. Disregard the note authorizing RVR 1,800 with use of a flight director, autopilot, or HUD to decision altitude. Temporary cranes are located near RWY 31L.
