welcome to the accuracies of GPS!! This single device has amongst other things increased the chances of a mid air many times over.

I've seen an opposite tracking ANZ B767 1000ft blw me over the Tasman once that looked as tho it was going to split my TX aerial right down the middle!
Ok Dr with yet another gizzmo onboard what will be the new payload available? 3.2 people perhaps instead of four?
