Abstract:
1. A method for correcting an altitude reading on an altitude measuring device as a function of climate and/or temperature, the method comprising: determining a first altitude based on an average reference temperature value at sea level and an average air pressure reference value at sea level; determining as an ambient temperature a temperature at the first altitude determined at the measuring device; and determining a corrected average reference temperature value by altering the average reference temperature value at sea level to arrive at a corrected altitude reading, wherein the average reference temperature value at sea level is 288° K and the average air pressure reference value at sea level is 1013 mb, and the corrected average reference temperature value is determined when the ambient temperature deviates from a reference temperature value for the first altitude, the reference temperature value for the first altitude set with reference to the average reference temperature value.
