Yes, good point about the nearest airfield screen, I forgot about that. Very relevant, since Carlito's question was about diversions. But I'm not sure how many of the other features you mention would be useful
in a diversion scenario, Andrew.
In fact, just reading through Carlito's post, he said:
You're diverted ... you get out your whizz-wheel, you account for wind and variation and off you go
I wouldn't use a whiz-wheel for an in-flight diversion! I generally have a rough direction of where the wind is from and what effect it will have on me. For a long cross-country I use a "wind star" - pre-calculate the drift angle for each of the eight main headings (N, S, E, W, NE, SE, NW, SW) and then use the nearest one if I need to divert. Not that this is at all relevant to the use of GPS though!
