Thats an interesting point.
It's something I have been thinking about although since I am only a coupe of hours away from my 150h TT, not something I have been pursuing.
If you do whats seen as the 'conventional' modular route of PPL,CPL,TEIR - you basically do your PPL (45h), hour build up to 150h, do your CPL training which takes you to 175h, then TEIR which takes about 55h, and takes you to a total of 230h. As you fly past the 200h mark you get awarded your CPL ticket.
An alternative could be to do your PPL,TEIR then CPL. You do your PPL (45H TT which gives you about 10hP1), then build up another 60 to get 70P1 hours to start the TEIR which takes 55hoursish. This means you get your TEIR with about 160HTT under your belt, and then CPL training takes you to 185. You then need to build another 15hours to get 200H for CPL licence issue. You would find yourself short of P1 hours, so you need another 15H to take you up to the 100P1 hours you need for CPL Issue.
So....basically (and roughly - I am at work so typing quickly!)
PPL-CPL-TEIR - about 230HTT on completion
PPL-TEIR-CPL - about 215HTT on completion
Does that sound right? Is it actually cheaper to do it the that way round or am I missing something.
I realise there are night ratings etc to do, but in principle - thats it - right?
