A go-around might be expensive
If you think a go-around's expensive, try a smoking hole in the ground.
The other aspect of the cockpit gradient not often considered is when it is completely flat - ie. Mate A and Mate B off for a day out together where nobody ever really takes command of the aircraft. Works fine for Ops normal, but when the flashing lights come on and the "whoop-whoops" start, it rapidly goes downhill. I don't know if it's more of a Military crew issue, where the Aircraft Captain may not always be the "ranking officer", or whether there are any laid back 4 ringers out there happy to sit back and let the Right seater run the show.
