A mystery for all you clever types out there ....
Yesterday (glorious Sunday!) my wife and I flew from Leeds for a day out in her ancestral home of Edinburgh (explains why the MIL looks like Mel Gibson in Braveheart, and is equally scary
) Fantastic trip, glorious weather, etc etc, and then ..... at about 55degs 39.45mins North, just above Galashiels, the GPS signal to some of the onboard systems disappeared ...
I have a GNS430, which continued to work beautifully : so obviously that was receiving GPS signals. I also carry (for VFR trips) a pocket PC (moving map) attached to a GPS unit. That lost the plot. And finally, because I'm experimenting with different gear, I had onboard a tablet PC, also attached to yet another standalone GPS. That also lost the signal. Wierd.
Now, a while ago, I was travelling up to Glasgow, when exactly the same thing happened, at roughly the same latitude, but further over towards the west coast.
It's a strange thing : kind of like the Midwich Cuckoo effect. The signal reappeared at exactly the same place flying back South.
So : two queries here. Firstly, is there some sort of Bermuda Triangle thing going on in the Scottish lowlands ? And secondly, why would portable GPS units lose signal when the wired up GNS430 kept going nicely ?
And finally, I guess this is a salutory lesson to all those who put absolute dependence on hand-held GPS units ... keep hold of those maps !
