I know it’s dificult for recreational pilots to navigate the GA regulatory system, hence the reason for making up your own procedures. The safe operation of aircraft in busy airspace relies on every pilot using published standard operating procedures.
Here’s a link to the guidance document known as a Civil Aviation Advisory Publication (CAAP). You’ll note this is numbered 166, this isn’t a random number, it is the CAR the CAAP is addressing.
Your self designed procedures might be ok at quiet aerodromes, but they reduce safety at busy ones.
