150 driver, flying is not commonsense.
We have rules that have been around longer than you and I have been around
Why not follow them? I realize you have to actually read them, understand them and maybe even ask others to help you understand them. And be sure you ask someone who actually knows something like an FAA inspector here in the USA or whatever you call them in your country.
Commonsense? Hardly. It is well thought out rules that keep things safe, the only problem seems to be when they are not obeyed or understood.
When I was instructing, I would teach people on how to judge distance (without the use of DME, VOR, or GPS etc). Just having someone say: turn base over the power lines might work for one airfield, but what do you do if you don't have power lines at the next aerodrome?
