We fly into some small airfields, a few into uncontrolled airspace, often with short runways, limited approaches and rubbish weather.

You can do all of that and more with NJE. Flew the other day from Zurich to Samedan. A short flight from controled envirionment to a VFR uncontrolled short runway down a Swiss valley. As a company we did over 1000 airports last year with over 700 in Europe alone. Its quite usual to fly from a -30c airport to a +30 in the same flight with all the attendant wx pattern involved.
In Russia we've had flights where we have to have a Russian navigator on board because the fields dont appear on any charts. If there is a more challenging job out there then i have yet to see it and would be happy to be proved wrong.
As a NJE/Biz Jet pilot no two days are ever the same and some of them are eye openers.
