Ed:
 
     lets suppose it produces an accurate figure at 10 feet or at ground level, I don't feel that guarantees it will give an accurate reading at various higher altitudes
 
Again, I do not know. I'm just wondering.

Bob,

 

The newer GPS units with the WAAS (wide area augmentation system) capability turned on can be pretty accurate in altitude.  I’d watch for stability in the numbers while flying and compare it to field altitude when parked by the sign.  Maybe I’d even have my copilot take a GPS altitude reading while I did a high speed pass 10 feet above the runway for an accuracy check.

 

My 7-year old $99 cheapie GPS doesn’t give me accurate nor stable altitude info.

Hi Again All...
 
How accurate would the elevation data be when taken from a GPS Unit? Could you correlate the altimeter to the gps while en route?
 
Just a thought.
 
Cheers
