Probably the quickest way to a PPL was an intensive program I underwent in 1974 as an Air Cadet living on the base at CFB Penhold in Alberta, Canada, using the old training resources of the Commonwealth Air training program (where in WWII many ANZAC & UK pilots trained).
It was a 4 week program in mid-summer. Each weekday had at least 3 hours of ground school (Theory of flight, Airframes & designs, Aero Engines, Meteorology, Air Regulations, Radio, Cross Country Navigation, etc. etc.). Weather permitting, each weekday also had a pre-flight training plan, followed by an airborne component. In poor weather it was more ground school, or exams.
For me, this flying was done in a Cessna 150, and I went solo at 10.5 hours. Including the dual hours, my logbook shows a total of 36 airborne hours to complete my PPL with a cross-country endorsement.
I probably had an advantage, since 2 years earlier I did much the same process to get my Canadian Glider Pilot’s License at the same venue, so I had plenty of prior experience in the local area, and with pre-existing stick & rudder skills (both with aerotow & winch launches).
I’m glad I did it early in life, as those early lessons stick with me at all times when airborne. Had I tried to learn it all later in life, around family commitments & working life, it would have much different, and much slower overall, I’m sure.
My advice… Just be patient and keep the training work as frequent as possible, so you retain your experience into each subsequent lesson.
