This is korean Air you are talking about.Anything is possible. Loss of face.
Pushback in ALLIGN,you gonna lose all your NAV data.To regain it you need a full reallignment.Takes 10 minutes to do it.But if you sw it to ATT,you can still use the HDG and ATT mode(Basic flying modes).And this mode you dont need allignment time.How are they going to answer to their management about the delay and lose face over such failure.
So think about it?possible?
