Hi there,. .. .I did my CPL on a complex single (beech sierra) at Professional Air Training at Bournemouth. Straight after that Idid my my ME on a Duchess which I then continued flying for the ME IR. I got some additional ours twin by doing it that way while keeping the CPL flying straight forward.. .. .For me that worked well. Doing a twin CPL seems a bit over the top but maybe the airline customers of BAE like it?
