Hi,

I like to use the max. "Geographical Range" (formula) one can observe the distance to the horizon, and then edit in: options / vis. options / max. Upper Visibility.
What confuses me is that on that option page, the distances units are SM, but in the manual (pg.40) they talk about NM ???!!!
What are the right units ?!
