Cat II/III App
I have a question regarding CAT II/III approaches.
1. Why do airports have a holding point which is further from the runway when aircraft are making CAT II/III approaches. Is it something to do with protecting the LLZ signal, or to protect departing aircraft from those making a go-around from a low altitude?
2. Can CAT III approaches be made at all aiports with an ILS. If not, how would a pilot know which CAT of approach he is supposed to follow?
3. Do CAT III approaches have to be performed using the Autopilot?
