gps altitude - best use of equipment
ever checked the tolerance of your gps altimeter at the stand?
ever been worried about too complicated procedures for temperature correction?
would it make sense to use lower indication comparing pressure altitude and gps altitude when it comes to obstacle clearance, eg during approach or during engine failure procedures?
or is it better to distract yourself from flying by filling in excel spreadsheets with data and waiting for the erroneous outputs?
when gps altitude is made available to pilots on an airliner would expect tolerance of indication should be published...
