Altimeter accuracy
"Jim Stewart" wrote in message
... How close should an altimeter be to field elevation when set to the pressure indicated by the field's AWOS? I'm seeing a 50' error. What's the accuracy of the AWOS? -- Geoff The Sea Hawk at Wow Way d0t Com remove spaces and make the obvious substitutions to reply by mail When immigration is outlawed, only outlaws will immigrate.

Glad you asked. I called some friends at Allweather (which made the AWOS at my field) and they said the units are factory calibrated to +/- 5 feet and that FAA specifications are +/- 20 feet. -- Geoff The Sea Hawk at Wow Way d0t Com remove spaces and make the obvious substitutions to reply by mail When immigration is outlawed, only outlaws will immigrate.
