It is not acceleration. It is speed. GPS travels much faster than we do. I
doubt we have clocks accurate enough to measure the relativistic effects at
our speeds.

And climbing has nothing to do with relativity.

Duh.

The clock on your aircraft runs slower as you accelerate, due to
relativistic
effects. But then it also runs faster as you climb, again due to
relativistic
effects. Do you take these effects into account in your on-board
calculations?

[And while they may be trivial for aircraft, they are not in all
cases--the
GPS has to be adjusted for these effects to maintain accuracy, for
example.]
