From not being able to land in 25kts cross being able to land in 35kts. From not being able to brake for an exit, being able to steer it like michael schumacher. And all this in 1 day!
What happened when they pinned that 4rd stripe on your shoulder. Got hit by the holy spirit or something? How do you expect f/o's to gain experience?
You need to do it a couple of times to see how hard you need to brake but it ain't rocket science. Keep track of the groundspeed and realise what taxyspeed you need for a highspeed turnoff/ 90 degree turn. And offcourse pick a sensible autobrake setting.
