Actually, the aircraft needs to flare so it will usually enter a flare manuever at approximately 50 feet. Following the GS down all the way without flaring might be what causes funny stuff to happenThis is because the last 50ft of the GS can do some funny stuff.
I think you missed my point. I was trying to show you that it's the same GS for a CAT III approach as it is for a normal ILS. The only difference is YOUR certification or authorization to use CAT II or III. I believe you said the GS is not accurate below DH."Crosswind79 said:I'll stay on it to DH....After DH, the glide slope is not accurate under a category one approach - only category II and III
The Force?side stick-n said:Gotta chime in here. If it is not legal to use the GS below 200' on a CAT I approach, then please explain how it can be legal to continue below minimums to 100' above the TDZ with only the approach light system in sight. Uh, what do you plan to use for vertical guidance between 200' and 100'?
Disregarding the GS and using the approach lights as vertical reference can and has put planes into the ground. Here's a scenario that I had about an hour and a half ago.cale42 said:If you are using the approach lights to go from DH to 100'AGL you ought to be using the approach lights as your vertical guidance, you have now transferred from an instrument to a visual approach.

And this brings us ALL THE WAY back to the original question of whether the glideslope is accurate below DH. I never said that I or that I recommend doing this unless specifically authorized and train to do, so I stand by my original answer that "Yes--it is accurate." Don't know where all that other stuff came from about vertical guidance from DH to 100' agl. The problem is that too many people try to read too much into something. A glideslope gives you reverse sensing if you fly an ILS inverted. Will I do it? No way!!!atldc9 said:We are authorized and routinely perform autoland approaches to CAT 1 ILS approaches.
