One or two posts refer to,quote: "only two autopilots,fail passive,so Cat3A only". .. .Not sure about that one being correct,I believe (prepare to be shot down by Airbus pilots)the A320 series only have 2AP's,but 3ADC/IRU,so Cat3B.. .. .I think it's probably the centerline guidance,(among other things)that give it the 3B capability.. . . . <small>[ 27 March 2002, 15:36: Message edited by: moleslayer ]</small>
