So, after all that complaining about too much automation, it seems that too little automation can shoot you in the foot as well…
I feel for those guys, probably got a few runway changes and were finally cleared visual approach, easy pitfall, especially with nice weather, to choose a low level of automation.
Sometimes it's just better to stay on AP, intercept the ILS (was it on?) watch what's it doing and click it off when you are stable at 1000'.
Just my 2P, wonder what (really) happened..
