Please explain how 2C/1000 is used in altimeter calibration. I did not
know altimeters had any temperature corrections.



Altimeters are preasure guages with a scale in feet. They assume a pressure
lapse rate with altitude and the pressure lapse rate that they use is ISA
whch assumes 15C at SL and 2C/1000'.


Last I knew C was a unit of temperature, not pressure.
