- NOTAMs that are both airfield and enroute appear twice (e.g. Redhill NDB)
This has been fixed.
- could do with finer control over the NOTAMs displayed, e.g. daytime flights would not need to know about obstruction lights, IFR OCAS would not need flow control NOTAMs; perhaps some template options aimed at day VFR, night 'VFR', IFR OCAS and complete?
Obviously the mechanics of the filtering aren't difficult now the infrastructure is there. It's more a question of not overwhelming the user with options - cerrtainly filtering on each and every subject would probably do this. Some presets could work, as you suggest, but then there is debate about what is relevant to each type of flight. I'll think about it.
- plot on map didn't work for me (just got a red star marking my destination)
That's a shame, because this is really useful when it works. I'd like to fix this but I'll need some more info. Any chance you could let me know what browser you're using and also send me a screen shot of your browser so I can see exactly what you're seeing?
- a base map marking airfields and major towns would be better than one showing roads
This isn't going to happen I'm afraid. It would be nice I suppose, but personally I don't think it's a big deal - the point is to be able to see where the things are and you can do that easily enough even with roads on the map. It's a question of the source of the maps and Google map API.
Thanks for the feedback; it's very useful.
Edited to say:
I now know that the maps relate to a problem specific to Internet Explorer, which I'll have a look at. In the mean time, use Firefox.
