Fuji, in that case it hasn't been done has it!
Why are NOTAMs not included? A truly integrated system would do it all, not miss out fairly vital bits of info.
Johnm, I have no idea why there is such a lot of passion aroused when the subject of GPS is raised, but I agree that it's all a bit silly.
GPS is brilliant and an incredible aid to safety, I think the nay-sayers have just never used it fully or experienced the piece of mind it can bring. Having operated for a long time without it and a fair while with it, I for one never go anywhere without having a handheld unit in my headset case. You never know when it may come in useful. Having a proper panel mounted moving map display in colour is even better!
