I dunno about you, UKAVIATOR but regarding to the ‘hatches and harness secure’ bit, I was taught to do all that downwind – Brakes – off, undercarriage – down, Mixture – Rich, Fuel – On and sufficient, Carb heat – checked, hatches and harness – secure.
Its worked for me for the past 8yrs and was taught to me by a few different instructors.
