It's not helpful is it? but it can't be a 1,2,3, thing and that's often what students too often think things should be. There's NO single answer. Be situationally AWARE and tailor your (minimum and rehearsed) TALK to each situation. Like at a Controlled aerodrome you must get a Clearence to LAND but it doesn't GUARANTEE the runway is unoccupied. You still need your brain and your eyes. ANY DOUBT make it NO doubt if you can.. With SOME instructors you GET THERE despite them not because of them and they do show you what YOU should not become like. . Nev
