Or it could be seen as valuable experience of the type that is no where to be found in Europe. I think worrying about what chief pilots think is a bit of a non issue considering there is very little under the pilots belt at present anyway. The worst case scenario is pilot has more experience and rated with experience in arguably a demanding and new environment but will need some extra training to meet European 'chief pilot' standards.
It may not be everyone's cup of tea but if pilots from Europe can go to Africa to build time in a 208 why not Indonesia in a more sophisticated aircraft. Expressing your views on what a 'chief pilot' will think is rather presumptuous.
