Career Guidance - Flight Training South Africa Pilot Training Garden Route
Give the above article a read, very informative(Wish I had taken Captain Waldeck's advice). As mentioned by Captain Waldeck be wary about school's that requires a huge non-refundable deposit. Don't become fixated with this "Top" school ****, there are plenty of smaller cheaper schools offering better training than supposed "Top" schools.
If you insist on a "Top" school pay the deposit for a PPL only, if you are satisfied with the school then go ahead and pay the deposit for a CPL. As said over and over again visit the school's; talk to the students.
