Something I find very frustrating in FS is none of the map screens give you any indication of the distances when you zoom in and out. Is there any way of knowing what they are without painstakingly working it out for each map view?
No, it's not designed with that feature. The scale would change with each click of the mouse.
Although the scale changes when you zoom in and out has anyone recorded the distances? Maybe for the view when the airport glideslopes first appear?
Those green icons are the Localizer and they appear to be about 5 NM in length(nothing to do with there usable range). Another thing to remember is that 1 degree of latitude is 60 NM(doesn't work with longitude).
Thats helpful. Cheers. 😀
