It would be really useful as part of a complete VFR planning solution to have the facility to calculate sunrise and sunset times for your current GPS position and for other airports or locations, as can be done for example with Garmin 296. Formulae accurate to a minute or two (at least between -72 and +72 latitude) are freely downloadable from NOAA. For now I've coded them in MortScript as an add-on, but it would be a really useful addition to the product (at least for me as the pilot of a strictly Day VFR permit machine).

We do hear this request from time to time and will probably get around to it at some point. It's not at the top of the priority list but perhaps it'll get there if more people contribute to this thread saying how it would be useful to them.

Gets my vote.



A simple practical tool that would be very useful would be a post-flight analysis type thing that could tell me what time I passed sunset/sunset+30. That would make filling in my logbook much, much easier!



To make it very clever, how about a predicted radius of action before sunset/sunset+ xmins? On request, and based on current speed, draw an area that you can still get to before sunset at that point. I accept that could be a fairly big number cruncher... but a challenge for someone out there!

Dear Tim,

Before SkyDemon came along I used AeroWeather for most of the weather related info, now I only really use it to get sunrise/sunset info. So this gets my vote also.

We've added sunrise and sunset times into the forthcoming 2.4.2 version.

Hello Tim,

Thats super!

Thanks for your excelent service and software again!

Kind Regards

(I will inform my friend/pilot Stefan).

I notice that V2.4.2 has a bit of a typo on the Ipad sunset/sunrise feature. It appears as SUNRISE and SUNRISE. Trivial really since it is obvious what is meant but worth putting right on a future version perhaps. Great software though.
