Is there any reason why the runways of some airfield disappear as you zoom out, while others remain? It's a bit irritating when planning long journeys because you can't select the airfield as a starting waypoint at the desired levels of zoom (1:560,000 in my case). All you see is a coloured circle which denotes the ATZ. Airfields affected include Netherthorpe, Wickenby, Clacton and Derby on my copy of Skydemon (2.4.2.16291)

I thought that might be the case, but it does Introduce a problem. It isn't possible to select those airfields as departure points when they are zoomed out even though they are licensed aerodromes at any scale smaller than half mill as far as I can see. It's mildly irritating seeing microlight strips still on the map at those scales. You leave the ATZ in place at small scales so it would be nice to leave a circle in the middle so we can plan from these airfields.

Can't you just zoom in a bit to choose the airfield? Would you rather one airfield's label obscured another - which would be the only other way.
