GPS altitude discrepancies
Sometimes the GPS is closer at hand than the map. Also, I don't live in
Kansas so my airports aren't flat. I would never set my altimeter while aloft with the GPS since the barometric altitude provides the necessary separation from other aircraft. I would check my GPS altitude with charted high terrain altitudes to guage VFR clearance margins. -- Best Regards, Mike http://photoshow.comcast.net/mikenoel "Roy Smith" wrote in message ... Mike Noel wrote: At airports that don't report altimeter settings I set my altimeter according to my GPS altitude and this has given me a reasonable ground MSL according to the published altitude of the airport. How is this better than the traditional way of just setting your altimeter to indicate the published field elevation? THere's only two reasons you want to know your altitude. One is to know how high you are relative to the ground, the other is to know how high you are relative to other airplanes. Setting your altimeter by the GPS gives you neither. |
