Ok
I'm not a student any more but I sure don't know the answer to this from my training.
When I am flying cross country and I set my altitude by GPS ATC will tell me that I my transponder is reporting about 400 feet lower than my GPS Altitude.
If I set my Altimeter to the setting they give me then the Transponder and my Altimeter will match up. However they don't match my GPS altitude.
So should I be flying at altimeter altitude or at GPS altitude.
And yes I am familiar with GPS altitude being off by plus or minus 75 feet most of the time.
So what should it be?
GPS Altitude or Altimeter altitude?
Or is there some thing wrong with my equipment?
Thanks
