Got my PPL down there in 2009.
Below some personal experience:
Instructors: Few but all of them good or very good.
Aircrafts: Old but well maintained. Not many planes so I had problems to book a flight.
Ground School: Intensive and excellent
Weather: Is the worst thing of Port Elizabeth (for training). During summer it’s windy and during winter cloudy. Bear in mind that weather will definitely delay your training.
City: Beautiful, calm and cheap.
Algoa Club: Friendly atmosphere
Airport: Not so big to waste time waiting for clearance or taxing, but not to small hence you will be exposed to airliners commercial aviation from the beginning.
