Mmmmm ...
Interestingly ... in the UAE there IS (was?) a limitation on the number of types that one can have on one's license at any one time ... and that number is (was?) 3 ..
If an operator wishes to have a pilot with 3 types already on his license fly another a/c type they are (were) required to have one of the previous type ratings dropped off the license in question ...
So it would seem that ... that WAS the interpretation of the regulation in some areas.
Go figure
