If SACAA continues to adapt towards JAA principles it may become legally impossible to priviledge more than 2 type ratings professionally at a given time or a maximum of 3 for TRI/TRE purposes in the near future.
Actually a good system in my view in terms of safety and might open doors for new people to get jobs, to move up and be forced to receive good training and then to concentrate on a maximum of two types.
This will force all those guys with numerous ratings to make a choice, which ones they want to keep and employ. So the possiblilty to fly charter on one other type still remains but anything further would become impossible. That would already help a lot and would also be good for the industry as well as the job market. Not for the individual freelancer though...
