320 Autoland
Hi Toby,
If you are still looking for referance, I take it you have the FCOM?
If so, you might find plenty of info in..
FCOM 4.5.70
In particular,
TASK SHARING FOR CAT I APPROACH (or better) and
TASK SHARING FOR CAT III APPROACH/LANDING WITHOUT DH
There are a few notes at the bottom that might help.
Cheers

Guys, IAW "my concierge can fly it " policy, Airbus industry allows autoland wherever and whenever operator deems it safe. I've came across two examples:
Airline X allows autoland only on CAT2 (or better) certified ILSes with LVP in force. Practice autolands can be performed in VMC only and again strictly on CAT II ILSes.
Airline Y allows autoland on any ole ILS, as long as rollout is not used on CAT1. AP has to be disengaged after the mainwheels touch down but before nosewheel is down.
I'm all X. It's very tempting to just sit back and let 320 guide you, but if you succumb, you'll turn into flying imbecile very rapidly.

In my company (Z) everybody tries to avoid autoland (scheduled every 1st and 15th for fleet monitoring), manual landings are much more fun. I thought it would be the case for most pilots...

Agreed, I am always reluctant to give away my landing to a computer but it does two things:
1. Fulfil a mandatory company requirement of 2 autolands per month
2. Keeps you in practice for when the RVR is 75m!

It is my understanding that the ILS beam quality may not be suitable for automatic landings on all CAT I installations. Deficient beam quality combined with an unusual terrain profile could lead to less than optimal autoflight performance that could occur at an altitude that may make timely corrective action problematic.
Below is an excerpt from the FCOM Autoflight Limitations section, which I have seen for a variety of current models of Airbus aircraft. I know of one operator that only permits automatic landings on CAT II/III ground installations. This is because they do not want to take the time to evaluate CAT I ILS beam quality at each airport. I would be interested in learning how other operators are dealing with this issue.

AUTOMATIC LANDING IN CAT I OR BETTER WEATHER CONDITIONS
The automatic landing system’s performance has been demonstrated on runways equipped with CAT II or CAT III approaches. However, automatic landing in CAT I or better weather conditions is possible on CAT I ground installations or on CAT II/III ground installations when ILS sensitive areas are not protected, if the following precautions are taken:
• The airline has checked that the ILS beam quality, and the effect of the terrain profile before the runway have no adverse effect on AP/FD guidance. In particular, the effect of terrain discontinuities within 300 meters before the runway threshold must be evaluated.
