with present GPS technology, pressure altimeters remain more accurate for measuring altitude change. This
is why airplanes still rely on pressure altimeters, not GPS.
Finally, the DENSITY ALTITUDE screen is calculated from the absolute values of station pressure,
relative humidity and temperature, and is not aff ected by the reference values entered in the BARO and
ALTITUDE screens.
