Altimeter Recalibration?

[Jeff Olson]

Is it possible to recalibrate the altimeter?

We live on a 50-foot bluff above the Puget Sound, yet my altimeter says I am 32 feet below sea level. I doubt the Puget Sound is below sea level…

There is no actual recalibration, it should recalibrate after losing GPS signal. It also has a +/-100ft range of accuracy

Altimeters are pressure instruments and in an aircraft can be recalibrated for altitude hight etc as a pilot I'm ok if I can see the ground in a grenadier it's not a problem.

If youre at 14000 or 14100 ft, the difference isnt going to matter. What matters would be your change in altitude as you travel (if at all). This isnt a surveying tool. If you need absolute, download a usgs map into something like avenza, or whatever people are using nowadays.

As far as I know, the altimeter operates without taking air pressure into account and only shows the GPS altitude, which is inherently much less accurate than the lateral position. So it can't be calibrated..
