Would it be possible to show the current Sunrise/Sunset and start/end of civil twiligth for individual airports? That would be so helpful for planning...

+1!  Thanks for suggesting this.  I've wished for it many times in flight, but keep forgetting to ask for it here.

Our old (25 years) King LORAN has this feature. (SS/SR) It's probably a well-known calculation involving lat/long and current date count of year. (We have a wall switch that controls outdoor lighting using an "astronomical" clock using this info.)

At first I thought it was a silly marketing thing. But I ended up using it quite a lot. Not for legal purposes. Just to know how dark it was going to be if we extended a flight. (Not all airports had/have lights too.)

Since some tend to be purists here, I should point out that elevation can affect SS/SR too. But to the nearest minute should be good enough.

This is only one reason why I keep asking for a spreadsheet app included in the iFly GPS app.  I have the SR/SS spreadsheet in my tablet.  It's not a very big calculation.  I also have the moon cycle spreadsheet on my tablet but that one does require quite abit of data and calculation.  Anyway, I find both of these spreadsheets very useful when flying long x-countries.  I won't think of flying very far from home without all of my aviation spreadsheets!  -  Jim Williams

What would be the benefit of including those spreadsheets in iFly GPS vs using some other spreadsheet software loaded on your tablet?
