Lack of internet access or mobile phone coverage shouldn't stop you from aviating
... true, but lack of knowledge of NOTAMs etc may well do!!!
By the way, thanks for "volunteering" the FIS units to give you information. Not saying they won't help, but I doubt they'd welcome your call because what you ask is much easier said than done... they'd need knowledge of your route (fairly intimate knowledge if it was outside the local area), your level and times. Having plotted all that information, they'd probably need to go onto the CAA Website to extract the latest warnings, glean out what was relevant before they'd be able to pass it onto you... or of course you could just do it yourself?
