Batty and jack the lad,
Have you ever diverted anywhere ?
The aircraft dosn't know what the weather is.
Common sense guys,
let the aircraft land, pull reverse, stop on the runway, (you don't need to worry about controlling the thing on the ground since to be cat2 it would have to have roll out guidance), stop engines, call services, go to pub .
or
Follow sopa's - go around trying not to rip off flaps and remembering to bring gear up, check fuel, divert to somewhere no one wants to go, get medical assistance on the wireless, sort out any other failiures you might have on the way (hydraulics failiure etc) fly to an airfield you may not know, get patient stable (read dead !)
i take it you two fellows are f/o's !!
