I was just wondering if there was something I've missed to get additional visual items displayed on the SD charts (both on my PC for planning and on the iPad for Navigation).

The best example I have is the various white horses around me as whilst Avebury is noted as a VRP, the white horses aren't marked in SD but they are on the CAA charts (my 1:500,000 chart has them clearly).

As a secondary observation, the appearance of roads and rivers can be quite different - comparing the river betwen Avebury and Marlborough, the CAA map has a lot of detail (despite not being zoomable in any way) whereas the SD one is a lot of straight lines (very obvious when zoomed in).

The same is evident on the A361 between Avebury and Wroughton, there is a marked bend in the road, clearly visible on the CAA map but completely absent on the SD plot.

I understand that it needs to be sampled as straight lines, but it seems that not enough sampling points have been used to give a true indication of the river shape, though maybe this is to reduce the data footprint.

I guess as SD is being used with GPS, it is not as important to have totally accurate mapping - but as there is an option to print the route, I was a little suprised they are not that accurate...

The SD Charts are just right for the job they are designed for, better than the Garmin on hardware twice the price. Those of you that have a problem with map size and or folding should get the CAA MemoryMap for your area. France is also available. Then plan your flight on SD repeat on to paper version ( to stay legal) then copy to MM and print out A4 sheets of flight, Use for the one flight, scribble clearances squawks and whatever on them. And then throw away and get a new clean set for the next flight. By combining these 2 sets of planning software you will have to work very hard to get unsure of position!! And you will not break the bank.

But isn't Skydemon available as a non-navigation version too?

I accept that for live flight, the detail levels are OK but surely for anyone that bought it for pre-planning, the argument that you don't need accurate detail when SD is telling you where you are doesn't work? (Of course, I don't know what % of SD subscribers take the Nav option).

Just a shame to have to add another step (whether that be drawing it onto a chart myself or doing so through another application) when SD could let me do it with a click of the Print button.
