Fig.1) The atmospheric pressure where the vehicle is displayed.  atmospheric pressure decreases as vehicle going up to higher 
          altitude.  The pressure at average level of sea surface is regarded as 1atm and, check if the pressure different from 1 atm
          is displayed. ( 1 atm is correct pressure)
