Correct me if I知 wrong!
According to JAR-OPS (not any specific OM) I have 3 statements. Please correct me if im wrong!
1, I知 planning a flight to a large international airport at night. Minimums for landing is RVR 550. In the TAF for the ETA (1hr before and 1 hr after) the weather says Vis 400. In this case I only need one alternate because I use the conversion factor RVR=VIS *2 (night and HI intensity approach lights)
2, I知 now flying to this airport and Im about to land and the tower reports VIS 400. Minimums RVR 550. They are not reporting RVR because the RVR equipment is U/S. I can now land because I use the conversion factor RVR=VIS *2 (night and HI intensity approach lights)
3, I知 out flying and going in to an airport that only has a VOR approach. The tower is reporting VIS 10km, Broken 300. Minimums for the VOR approach is, 2000ft and MDH 420 ft. The airport is at sea level. I can now land because ceiling is only for planning purposes in Non-precision approaches.
Thank you, and if you think I知 wrong please refer to a JAR document!!!
