I'm doing this introduction very late but I did want to post a thanks.
I passed my PPL(A) flight test on 30/10 and that has closed out a bit of a long journey (15 years) to getting it. Through it I've been using your books and this forum to study for not only my PPL(A) exam but also the complete set of CPL(A) exams.
The books are great and the NAV workbook is a great study tool. If I was doing it all over again I would also love to see a CPL-Perf workbook chock full off questions just like the NAV workbook.
I'm off to spend some quality time with an SR22 and CT4 once CASA finally issues my license but I'll see you for PIFR/IREX next year.
