Such a function is also the result of hard work and at the same time an expression of high respect: Captain Erik Dalege (born 1962) is now the president of the umbrella organisation of European Pilots, EMPA for short (European Maritime Pilots Organisation).
Each pilot association and each country can get a good overview of how other colleagues approach safety.
Ship crews can see which rules apply in which country.
In any case, this list from IMPA is worth looking through and reading.
On the first day of the "IMPA safety ladder campaign 2020", Joris Stuip, Vice President PTR Holland is rightly upset about obviously fake and manipulated certificates at Pilot Ladders. They are playing with the safety of the pilots.
