Well until you do the maths!
There are 196 countries in the world and whilst some of them don't figure at all in aviation terms, others are particularly dominant in this aspect. But keeping things simple, if you divide 255000 by 196 the number comes down to 1301
Divide that result by 10 (years) and the number comes down to 130.
That is Two and a half pilots per week per nation on a non-weighted average.
Not very exciting is it!
