- You would need a GPS program which would compare your location to a sea level database.
Although it would be neat, I think the demand for such an app is too small.02-04-09 11:44 PMLike 0 -
But after that stupid level program came out, all the contractors in the world came out in the forums and said they would slap an otterbox on their Storm and start leveling stuff.

When the flight attendant tells you to put your phone in "Airplane Mode", it would turn off all abilities to send/receive, to include the ability to send/receive location via GPS/aGPS. I've seen flight attendants whip out a muay thai clinch on someone who had their GPS on during a flight. Just kidding about the muay thai clinch.
Now if you're on those British Airways flights where they are allowing you to talk on your phone during the flight, I'm sure you could get away with it.02-05-09 12:07 AMLike 0 - It wouldn't be possible to do it from a plane or even a ladder etc. You would have to be on the ground for it to work.
The gps can't tell if you're on the ground or not it can only tell (x,y) not z. So it would only work when on the ground.
Skiers would probably get the most use out of it.02-05-09 12:17 AMLike 0 - It wouldn't be possible to do it from a plane or even a ladder etc. You would have to be on the ground for it to work.

GPS can indeed provide elevation. No need for any kind of topography database or other reference (outside of the GPS satellites own self positional reference that is.)
As an Avionics Tech who has spent years working with GPS systems, yes GPS can (and does when asked to do so) provide elevation. Pitot/Barometric, and/or Radio systems combined are still more utilized on aircraft because they can provide more information outside of just elevation (atmospheric/weather conditions, actual altitude above current ground position etc...) , however GPS is still quite capable of providing elevation/altitude above sea level.Last edited by rmjones101; 02-05-09 at 04:38 AM.

Exactly how accurate is the altitude on a GPS? I'll bet my life on a correctly set barometric altimeter, but not a GPS. Sometimes it matches, sometimes it doesn't.
Keep in mine the planes I fly are NOT equipped with IFR certified GPS systems. That might have something to do with it.
I've never scientifically tested this but it seems the variation comes from how far off of 29.92 the calibration is.02-05-09 01:16 PMLike 0 - DenverRalphyRetired Network Mod
However GPS elevation is really only good for general reference. Aircraft wouldn't use it for Autopilot (well, altitude hold features anyway) or Landing systems. Not because of the accuracy, but because of the speed (or perhaps lack of speed I should say) in which it calculates and updates. It's simply not fast enough.Last edited by rmjones101; 02-05-09 at 01:50 PM.

It's a bit clunky to change the options, but beyond that(for me), it's not that big of a deal.
I like having it set(in options) to show my location on Google Maps and let it update. Nice work around for the aGPS problems in google maps...02-05-09 02:55 PMLike 0 - It wouldn't be possible to do it from a plane or even a ladder etc. You would have to be on the ground for it to work.

I would suggest getting an aviation GPS for anything more than entertaining yourself in the back of an airliner though.
