I came across a Low Alt enroute chart for the UK yesterday and it got me wondering...
If you're flying IFR in a SEP, how do you FPL a route through controlled airspace? For example; if you take the LTMA, most of the airways have a lower limit starting at about FL090-FL100 and I'm guessing a climb to this sort of ALT in your average C172 etc would be quite a hike?
As an example, I submitted a test FPL to the CFMU validation system for a flight between Cranfield and Le Touquet. Funnily enough, it was acknowledged with "no errors" but in reality, would it be feasable to fly? The route was:
DCT BPK DCT LAM DCT DVR L10 RINTI DCT (FL075)
Now, I'm just a PPL with no ratings so it's just for my own interest
