Surely you are not telling us all that the GPS accurately
recorded your true height but the barometric logger
got it wrong. This cannot be, and a valid trace as
well, this is blasphemy, the ICG sacred cow, the barometric
height widget has failed, the world will end.

Absolutely not. This is a genuine trace from my logger!
The logger is in the
glider, still sealed in position ready for inspection.
I go on holiday with
a lot of equipment but a vacuum pump is not one of
them! The GPS altitude
echoes the pressure altitude in a similar manner but
on a scale of perhaps
1:10

I'm thinking of claiming a record. I have a valid
IGC trace aquired
recently
in the Pyrenees during which I climbed to 79275'
( yes seventy nine
thousand
two hundred and seventy five feet ) after taking
off at 8228' - a 71000
plus
gain of height. The logger was sealed in the glider,
a nimbus 3 t, and
still is as is the trace, the flight was witnessed.

Although only dressed in shorts and t shirt I suffered
no high altitude
effects and the EDS O2 system worked perfectly. Lift
was frequently over
30
m/s although I'm damned if I can remember it being
that good.

Anyone interested in the trace can mail me for a
copy ( 40 kb )

You would not have used one of those little old vacuum
pump things to
prove a
point would you? ;-)
