Its not just the PPL that needs updating, its the whole system from PPL to CPL and right the way through to the IR.
Take the CPL for example, its nothing more than a 'posh' PPL - 25 hours of glide approaches, PFL's, and finding small cottages on remote hillsides, all in a supposedly 'complex' aircraft(Piper arrow

). Now look at the 'average' CPL student - 99% of them must be youngs boys and girls destined to fly an Airbus. What use is the current CPL syllabus to them?
The IR is just as bad, in fact, dont get me started!
