Hi!
Howzit?
Im doing my CPL in Durban at the Virginia Flight School. I've already had a PPL (former EASA now JAA)before I came here so I had to convert it to SA-CAA. (just finished that 3weeks ago)
That is not a problem at all. You have to write air law, meteorology and human performance. You can write the exams on-line in the school whenever you want. Than you fly a skills test with a grade 2 instructor. Usually they make you fly a dual cross country and some circuits before your skills test just to make sure that you are on a desired level for the test. It is same with the FAA licences as well.
Im very satisfied with the VFS so far.
If you need any detailed info about the school, living costs, accomodation, transportation, etc. I can send you an email.
Cheers
