But it still remains to be understood why they didn’t head to land and instead spent hours over the water. I didn’t study the area though. Perhaps visibility was low and he simply got lost, especially if all instruments stopped working, including GPS and VOR.
Could anyone explain this arc business? I’m imagining that the ping only gives information on which satellite and the distance from it or maybe even the angle. If so, once you have three satellites you can pinpoint the source.
