Having now planned and flown plenty of international trips with the able use of SkyDemon, I reckon it would be rather nice for the programming to have the facility to automatically identify when you are crossing an FIR boundary and to automatically present the FIR ID (eg EGTT, LFRR, EDLL or whatever) either in the PLOG or simply on the displayed chart alongside the crossing point. Such FIR ID changing as necessary when reversing the route.

At present the FIR ID's aren't displayed (or I can't find 'em!) and one has to look elsewhere.

eg Flying Calais to Koblenz one crosses from France into the Belgian FIR (EBBU) thence into the German(Langen) FIR (EDGG) and the reversed route to show change in FIR entries (in this case Germany(Langen) (EDGG) - Belgian (EBBU) - France (Paris) (LFFF).

Is it even possible? 

Thanks, that helps us understand what you're after. Since SkyDemon does flightplan preparation for you, though, we can't really use this to justify implementing some kind of feature to help with it. Even if you don't want to use SkyDemon to file flightplans for you, you can still hit the Flightplan button and see the flightplan form all prepared, comlete with your EET to all international FIR boundaries (with their codes).

Thanks Tim, In that case, that's what I'll do, copy out the SD flight plan and type in the relevant FIR ID's and their respective ETA', into AFPEx - It'll certainly save idle me unfolding millions of charts and searching the FIR boundaries for tiny print - Cheers
