During my recent return flight from Oshkosh, I stopped at Delta Co
(ESC) at Escanaba, Michigan, but when later looking at the flight log
(Garmin 296) of my trip, the stop at ESC did not show up. The track
feature showed that I was there, and zooming in showed my ground
maneuvers, but the log showed that I flew from Oshkosh to Clare Co
(80D), Michigan...409 miles and 5.4 hours...NOT! In looking at the
Green Bay Sectional later, I noticed that there was a note stating:
"Magnetic disturbance of as much as 14° exists at ground level at
Escanaba"
I asked the Garmin Tech Support team if this could have caused my
"non-stop", and their reply was:
"We have seen where external sources can have an effect on the
units. Having
a magnetic field that is that powerful could possibly cause problems
with
the unit. This could cause the unit to lose satellites reception and
many
other potential problems."
So the question is this: Have any of you had your GPS's flight log
fail to show a stop, or have you ever shown a stop that you didn't
really make? I have flown near an airport, turned around and flown
back and had the unit show a stop there, when in fact I did not stop,
and the tracks show this as a non-stopping incident.
