Here are a couple of really useful resources for mission planners.

The first will take all the guesswork out of tanker airspeeds, so we can accurately get indicated airspeeds spot on.

The second is a record of sun rise, sunset, moon rise etc including bearings, and even real world weather if you want to add that into missions. The link is pointing at Batumi, but it is a worldwide utility, so whichever map your mission is created on, you can extract the relevant information. It has been tested in DCS World, and they match very well.

I hope you find them handy.

Excellent resource thanks Neil.

Ripper is the guy to thank. He passed them on to me today.
