Hi - we tried out the ipad in anger at the weekend and still like it but discovered a few quirks, which I'll come to, but (through our own fault it seems) having checked that the Sky-Demon subscription was valid mis-understood the licensing model and therefore expected to have fully working version not a demo version limited to 30 minutes use.

Extended runway centrelines appear when you're nearing your destination (when available). There's no other logic than that, I don't think, so if you could give a specific example of planned route, aircraft position and failure to display them, we can look into it for you.

Regarding the airspace warning issue, I think what you're after is another kind of warning besides airspace. Our airspace warnings are just that: they warn about upcoming airspace. If you're within a piece of airspace you won't be further warned about it and this is by design, sorry.

We will look into the orientation change issue that you experienced.

Ahh - OK I didn't realise that the centre-lines only are applicable to the destination and not airfields in general. My mistake.

PS - Thanks for the clarifications - with so many devices out there it's good to have a good GPS with a good support forum.
