APP for Sunset and Sunrise times in flight?
Hello, just wondering which app do you find the best for calculating in flight sunset and sunrise times. (One that takes into account Flight Levels).
Thanks!
Thanks!

sunrise and sunset relates to being able to see visually for a landing.
surely altitude is a useless consideration?
my little garmin gps has a screen for first light last light given the location in question.
in australia you can get the first light/last light information as part of a weather briefing from the Bureau of Metrology (via air services australia)

Eight,
I think he needs it for other reasons. I don't think sun rays are needed for his landings. More a lack of them to let his SLF eat.

Sunrise and Sunset times for Ramadan
No app but this is what we use. You will need to get the actual sunset and sunrise time over the location ( LIDO or Jepp tables) you are flying over and calculate as indicated below
Sunset and sunrise time differences from ground to air can be approximated by using 1 minute and 30 seconds per 5000ft. E.g. Sunrise on ground in Dubai is at 05:30. To approximate sunrise time at FL 350: 35000 / 5000 = 7 7 x 1.5 = 10.5 minutes. Approximate sunrise time at FL 350 is.05:30 MINUS 10.5 min = 05:19 Sunset on ground in Dubai is at 19:15. To approximate sunset time at FL 350: 35000 / 5000 = 7 7 x 1.5 = 10.5 minutes. Approximate sunset time at FL 350 is. 19:15 PLUS 10.5 min = 19:26

Didnt, and still dont, have any app for this. Used the LIDO tables but a problem arises as you are doing 81/2 nm per minute as you are doing this. So the problem becomes WHERE will you be at sunset time? Took a good guess at the approximate wpt because it always goes dark around there when returning from europe.....LIDO corrected for longitude gave me an approximate sunset time and if that equates with your ETA at that waypoint then you have it cracked! If not, make a sensible decision to move back or forward a waypoint and try again....thanks for the altitude correction though, I guessed at about a 10 minute correction but nice to get it confirmed.
Having done all that the other night, my oppo, who was watching my mathematical shenanigans and also guessing somewhat wildly as to the time then produced his iphone app and pretty much confirmed what I had worked out!! Grrrrr!
Tried downloading an app today (doh, why didnt I think of that before?!!) and was unimpressed to find that I would need to upgrade to IOS 6 or something like that first, so gave up!! Far more satisfying to have worked it out for oneself....but there again, that sort of thing appeals to navigator types!!

Muslim pilot is very accurate.
Or you could be smart/utterly lazy like the EK pilots I heard few days ago asking Ankara control. The timing given to them was time for opening of fasting on the ground. :/

Discounting atmospheric effects and / or the effects of physics & gravity on light particles / light rays.... it's neigh on impossible to be certain of when is sunrise & sunset when sitting aboard a platform that is moving at 600 mph and / or taking account of ones groundspeed & altitude therein. Thus it's all something of a guess and therein some minutes added as a buffer on either side of ones guesstimated sunrise / sunset is probably good enough... and surely any lengthening of the period of fasting will simply add to the piety experienced by the adherents of the 'Religion of Peace'.

Mohammedanism, what is that?!
Can I add an extra 20kts to my V speeds in future or perhaps less?! Or should there be some discipline in the maintaining of all things calculated?

TwoTone-7: you're evidently something of a slave to precision and therein this should be an easy question for you: Q) How much does your aircraft actually weigh at any particular moment and please do explain how you came up with your answer ?
Wrt the other matter, and for your education & enlightenment, see: Mohammedan

Old King Coal, whether you may think of me being a slave to precision is subject to your speculative presumption and at the same time it goes on to mention within the article you posted that the term mohammedanism is wrong and to an extent, insulting. So, where do you stand in your labelling of people as Mohammedists?
Unfortunately, all too often. People of your opinion confine themselves to the keyboard and no further afield. : )

Leave the old farts be, they're too set in their ways.
Muslim Pilot / Prayer Inflight takes position, ETA, altitude, track and ground speed as inputs. It's used by quite a few Muslim pilots. If it's good enough for them, should be good enough for the fasting folks at the back who professes Islam.
Don't know about Mohammedans though...

For those non-muslims who may want to use the app.
Fasting should start at Fajr (Fajer) (which is actually 90 minutes before sunrise, not at sunrise as some pilots believe)
Fasting should end at Maghrib (sunset)
Those are the times used in the App
