Question to Mxmanic

It is not acceleration. It is speed. GPS travels much faster than we do.

No. There are nearly half a dozen relativistic effects that must be
compensated for in the GPS. The nominal clock frequencies, for example, must
be adjusted by slightly less than one part in two billion in order to adjust
for the cumulative relativistic effects.

I doubt we have clocks accurate enough to measure the relativistic effects at
our speeds.

Sure you do ... in your GPS receivers. The adjustments for relativistic
effects are necessary to make the receivers reasonably accurate.

Wow! That's useful information!

Mxsmanic,

Again, you have no clue what you are talking about. First, you are dodging
the subject, since the GPS measurements have nothing to do with the
aircraft's flight or climb. Second, the accurate clocks in GPS are not at
all in the receivers, but rather in the satellites. The receiver clock is
"told" by the satellites what time it is.

Your attempts at being an expert (or even a decent researcher) in every
field are pathetic and only serve to show how very little you really know.
Not knowing stuff is not a problem at all - until you claim to be a
know-it-all, like you do.

And those miniscule adjustments are only required at the speeds of the GPS
satellites, which are many thousands of miles per hour-not several tens of
miles per hour.
