The flight tracking systems uses the same measurements of altitude as what the aircraft's altimeter measures in the Primary Flight Display?
That is what I wish to know.
And what do they mean by "uncorrected"?
Does it mean that the flight tracking system assumes that there is no baro adjustments and the baro setting is always kept at 29.92?

I thought the altimeter settings are based off the elevation of the airport in MSL as instead of AGL.
For example, if an aircraft is at a field elevation of 800 feet, then I would assume that the altimeter is set to 800 feet and 0 feet.
Am I correct?
So, would these online flight tracking systems use the Altitudes based on AGL?
