Check out FOM 20.9.3.
You need to do one on your next trip but limited to CAT I mins until accomplished. You need to let dispatch know your CAT I limitation until you get the approach accomplished.
You regain recency by accomplishing the Autoland in CAT I or better conditions. Must be Captains autoland to a CAT II or III approach. Not a huge deal unless weather is below mins before accomplished and then not sure what they’d do? Delay or find another pilot?
Yes this is a weird deal for the FOs since you are only monitoring the approach but it won’t update until someone logs the Captains autoland in iCrew.
