September 23, 201015 yr Coming into Narita in CAT III conditions. I am fully set up for autoland established on loc and G/S flying straight and true just about to cross 1500 agl when tcas alarm sounds...plane goes into what appears to be go around mode automatically. throttle up nose up I immediately disconnect auto pilot and land the plane. Is this a safety feature of the md-11 when the tcas sounds under a certain altitude? The flight was ultimately sucessful I got my sim passengers there alive, but just curious why that happened.Guthrie Zuehlke
September 23, 201015 yr Commercial Member No, there is no such feature with the TCAS. In fact close to the ground the TCAS switches to TA only, no resolution advisories anymore. Don't know what happened on your flight. However, if in CATIII conditions you should NOT disconnect the AP and land manually but instead do a go around...Regards,Markus Markus Burkhard
