Amazingly the SA CAA is being very tardy about bringing in the JAA training regime in across the board - from the private thru commercial and ATPL. The JAA licences will soon replace the existing SA licences.This is also not helped by the majority of flight schools being understandedly reluctant to start any JAA training .At some flights schools there is a hostile opposition to bring in anything JAR.
Aerobatic Sean, I'm afraid you are not correct. SA is not going the JAR route and they will not replace the current licences.
I know a number of students who have completed their SA CPL/IR, then gone back to the UK, converted to JAR and it still worked out cheaper!
