You're right. AIM 1-1-20(a)(8) tells us that we should not use GPS altitude.
When WAAS is in common use this will probably change. Bob Gardner "EDR" wrote in message ... In article , Hankal wrote: I comply.Look at my GPS which is at 7060. I go down 50 feet the gps stays at 7060. I go up 100 feet the gps stays at 7060. GPS altitude is only accurate to +/-150 feet. It is a "rough" reference, not to be considered "precise". |
