This raises a question with me.Â* I've often heard that Cambridge started
the whole GPS flight logging thing.Â* If that is true, why did FAI come
up with a different file structure?Â* If it is true, why not simply use
the Cambridge file?Â* Is it not "secure" enough?

On April 6th of this year the GPS week will roll over and on some
older
instruments it could mess up the date. How many of our soaring
instruments
might have this problem?

I'm guessing that will be the final end of my 1994 Cambridge Model
10.
(It's already had the battery replaced, of course)


I've got a 1996 era Garmin backpacker gps still holding the correct
date.Â* Internal battery was replaced under warranty about 22 years
ago.

I'd be surprised if it suddenly got the wrong date on April 6, but
really doesn't matter anyway.Â* Lots of old Volksloggers got hit
with the
date problem, maybe they'd be more subject to failure if any of
them are
still in use.

Most of the Volksloggers were made with the Garmin GPS25 Engine,
same as
legacy Cambridge.

One rollover problem the Volkslogger doesn't have is due to the
robust chassis.
It makes a good wheel chock.

At least the Volksloggers put out actual IGC files.Â* The Models 10,
20, and 25 should have been relegated to wheel chock duty long before
the Volksloggers.
