With respect, you are talking complete rubbish!
FFF - So the reputable UK FTO I work for have got it all wrong then ??
Their ops manual which gives a number of CPL x/c qualifier routes is complete rubbish and not worth the paper its written on.....?? OK I'll let them know.
I was in a similar position and completed my CPL qualifier without having to ask an internet forum, but I wouldn't allow a student to go off and do his own thing if the approved routes are in the ops manual.
Therefore, it has everything to do with the FTO, especially if I am the instructor and the student has completed a route of his own that turns out to be insufficient.......with respect.
Other opinions are not complete rubbish just because they differ from yours....with respect.
