RVR & Takeoff Alternate Questions
Could someone shed some light on this? Please include a reference if you can.
1) Let say you are about to depart from an airport with RVR reporting less than 600 feet (and assuming you can depart with no less than 6/6/6) and the flight visibility is reported as 6 miles as it could possibly with shallow fog (measuring equipments at different heights) - I know RVR is controlling but would you be allowed in this case to use the reported flight visibility (greater than takeoff minimums) to essentially do a "normal takeoff" without having to go through all the "low visibility takeoff" requirements?
2) We all know a takeoff alternate is based on landing minimums at departure. From what I have read, it doesn't specify CAT I (even in my company OSPECS). Could you use CAT II or CAT III minimums to determine the need for a takeoff alternate provided you can shoot one of those approach single engine?
3) Does anyone know who and what equipment is certified CAT III C? I am under the impression that no one is in the United States but I am sure I may be wrong.
