The
elevation can be measured either with the GPS receiver or the pressure
sensor if the device is fitted with. Important point : once calibrated,
the elevation given by the pressure sensor is far more accurate than
the one given by the GPS receiver.
Display can be indifferently
defined as analog or digital, and the choice can be made independently
for the altimeter and the variometer.
Possibles units of measure for the elevation are meters or feet.
Possibles units of measure for the vertical speed are meters per second or feet per minute.
