      HINT: 

      • Standard atmospheric pressure is approximately 101 kPa (15 psi).
      • For every 100 m (328 ft) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.1 psi). This varies by weather.
    5. Compare the MAP and Atmosphere Pressure values in the Data List with the normal atmospheric value from the table.
