im curious as to the claim of difficuly as well. At my carrier we only
go as low as CAT II, and the only differences between that and a CAT I
for us is a QRH monitored approach checklist and briefing, making sure
the CAT II annunciator comes up and turns green, watching the needles
and looking for lights. I'd imagine autoland w/ autothrottles (neither
of which we have) to be less work, as you no longer have to find lights
and land the airplane. More stressful sure, but i wouldnt equate that
to more difficult. Granted, i fly a certain RJ made in brazil and not
a boeing (only been up front as a jumpseater) so perhaps my perspective
is off.
