One cautionary note - if you intend flyingin the UK when you return from Seth Efrika, either train for a JAR-FCL PPL(A) at a school which MUST be approved for the training - or else train for a SA PPL. When you return to the UK you may fly day VFR UK on your SA licence so long as it's current and valid. Establish how you will maintain its validity....
2 cases spring to mind. One pilot had a lapsed SA PPL and wanted to know how to use it to obtain a JAR-FCL PPL - he wasn't happy to learn that he needed to fly 35 hours (25 dual and 10 supervised solo), sit all the exams and do the JAR-FCL PPL(A) Skill Test. Neither was someone else who went to SA to do a PPL at a non-JAR school but didn't quite finish - he also needed to do 35 hours back in the UK.....
There are obvious plus points regarding training in SA, but beware of the traps for players when you get back to the UK....
