Hi There,
I am in the process of converting my Canadian ATPL to an SA one so have an insight to the process. Apparently the process of converting a CPL is very similar.
Firstly you have to have your licence validated by the SA CAA out here. This is basically a check by the CAA to ensure that your licence isn't a forgery. A word of warning here. I submitted my paperwork in January and still don't have the number required to write the 3 exams or do the flight test. I just heard that a Kiwi submitted his/her paperwork in November and has just received the necessary go ahead paperwork. It takes time so just be prepared to wait a while. On the upside the weather in Durban is fantastic so I don't mind studying by the pool after a nice 10 km run along the sea front ;-)
You are correct in the exams you need to write and the pass mark is 75%. I'm using the Avex notes with Aeronav for the law exam.
Then the flight test which for the ATPL is a renewal of an IF flight test, not sure what it is for the CPL.
It's best to write the exams first as they are valid for 36 months whereas the flight test is only good for 30 days.
If you have more questions then feel free to ask. My pain is your gain!!
