Hi,
regarding your 1st question, well it depends
.
- weather (if below CATII Autoland is required)
- airport facilities (CATIII ?)
- training of crew
- tech status of the airplane (MEL)
In our route system I do a maximum of 10 autolands/year. If you fly a lot into foggy GB it may be different
. So 99% are manually.
Concerning the 2nd part of your question. Basicly yes. You need CATIII ILS to do autoland, but if the weather is better you can also do autoland on a CATII/I runway with special care (depends on company SOP).
BTW "auto thrust reversers" ???
What's that?
Cheers
