The Bronze Badge requirements have had a bit of an evolution type history - the modern Bronze Badge requirements are totally different to what was required in the 70's/80's.
The exact procedure probably varied a little from club to club
My Bronze quals were similar to KnC - 2 x 30 min soaring flights off the winch (or 2 x 60 min flights off aerotow),Motorfalke flight for some Nav and Field Landing training/evaluation.3 x flights with the CFI for general handling,cable breaks etc including one simulated field landing into a very restricted part of the airfield plus of course written exam and some oral questions by CFI.
In those days the Bronze Badge was the cross country qualification - whereas nowadays there is a Cross Country Endorsment to qualify for x - country flying.
