thing
I take it you are in europe?
anyway, I know of a case of a brand new NON instrument rated pilot with a great new piper turbo arrow...full autopilot and nav package, deluxe.
was flying back from oregon to california...at night...went into a towering cu/thunderhead/lightning.
plane broke apart
now, I'm not blaming the plane or the autopilot...but the autopilot may have had too much and the pilot (biological) may have over controlled the plane.
you have had a good experience...hang on to it and the confidence...then use wisdom to avoid the same situation.
AS to the real question, you should hand fly enough ''sectors" (here in the USA, we say LEGS) so that you can handle all situations without an autopilot.
