What speed I will left the nosewheel off the ground?
All I ever do in my Bonanza is think about the glide speed clean and dirty and where I might go after the airport stops being an option.
110/90 paddock/road/beech/river.
That covers every 'decision' i will make.
This sounds like yet another example of instructors trying to ape 'airlines' but with no direct experience of it.
