43 - your correct but thats not getting to the issue.
Its 4 flights for the pilot plus the same for each of the other 217 checkers plus a play pilots by the FOI.
The point is all these new safer aircraft are jumped on by the casa wizards with all their rule interpretations and perfect world requirements.
Meanwhile the old clunkers which don't attract the casa FOI's desire or attention just continue on.
The new aircraft are never going to make money in charter and the Owner can live with that.
The problem is the aircraft gets hamstrung with training, crewing and over attention by casa. Eventually the owners get jack of it and gives charter a miss. The punters are then left with the old 20 - 35 year old aircraft again.
And this is after the frustrations of a 1 or 2 year delay in the issue of the AOC.
