Flying Airways in the UK?
Soon I may finally be able to file airways regularly in the UK using my FAA IR and an N-reg aircraft. However after doing my IR in 2008 and coming back to the UK looking over the airways charts has left me slightly bemused; for example, one regular flight that I might want to take would be from the south of England to Scotland, on inspection of the route it seems that from 0700-2000hrs airway N601 has a MEA of FL140, making it impassable without oxygen. In general a lot of the airways seem to have quite hight MEAs compared to the US, I guess because we have mainly class A only airways and only put them where commercial flights need them. Is there any way round this though? Is it possible to file an IFR flight plan that is only partly in the airways with some parts dipping below out of CAS?
