Soon to come:
Finnish tax as you would be base in HEL working for a Finnish airline. No way around that, legally that is, even if you are on paper based elsewhere. Tax people are looking contractors working in Finland with a magnifying glass due to the Blue1 contractor use in the last few years.
Grey area is, if a work permit, basically a D type Schengen visa (National rules, limited access to other Schengen countries) or a residence permit based on employment is required.
JAA/EASA ATPL or CPL. Validations of non JAA will stop April 2013 and by that time one must complete the 14 subjects with a prior approval from CAA on what credit is to be given if any and if a theoretical course is required.
Blue1 is just now in the process of sacking a large number of pilots in a pilot community that is relatively small even considering that Finland is a small country.
Other than the above Finnair has been a top notch operator for years with excellent service, maintenance and training. The postholder flight ops and training are very experienced and certainly know their jobs.
I have no doubt that if the tax, work permits, licence and labour are not an issue to an individual, NGA will have a good bunch of people to hang around when on the road and well maintained aircraft to fly.
