When, I got out of flying 5 years ago, the blind landings were just=20 starting to get approved, and there were relatively few planes crews=20 approved. There have been significant improvements in the equipment=20 available and quantity installed since then. I have to assume the air=20 carriers (airlines) have taken up on this, and new planes delivered have=20 the capability, many planes retrofitted, and crews trained and certified=20 as part of their routine required (annual) training. And then to=20 insurance carriers frequently have requirements that are beyond the FAA=20 or other government agencies. I recently had a friend with a homebuilt=20 aircraft install an EFIS (Electronic glass screen display) system in his=20 plane. This is common place today, where 7 years ago, the cost was=20 prohibitive. Here's the standard ILS (Instrument landing system) approach procedure=20 for our local airport showing 200' above, and 1/2 mile visibility as=20 minimums http://www.airnav.com/depart?http://155.178.201.160/d-tpp/1202/05703IL7.PDF Here's the Catagory III ILS at Cleveland's airport showing no vertical=20 restriction, but does have RVR 06 (Runway visual range =3D 600') which is=20 saying the pilot needs a little (600' @ 120 mph) sight distance to=20 navigate on the ground. There might be better info, but this is what I found quickly. http://en.wikipedia.org/wiki/Runway_visual_range http://www.allstar.fiu.edu/aero/ILS.htm And On 2/22/2012 8:56 AM, Sean Breheny wrote: > Hi Carl, > > Trying to understand your answer.
