| The height of the freezing level over the station is approximately 12000 FT. |
| Assuming that the MSL pressure is 1013.25 hPa the true altitude of an aircraft would actually be higher than the indicated altitude. |
| Assume the station is at MSL. Height in feet. Temperature in degrees 20000.-12 18000.-11 16000.-10 14000.-10 12000.-6 10000.-2 8000. +2 6000. +6 4000. +122000. +15 surface+15.Which of the following statements is correct ? The height of the freezing level over the station is approximately 12000 FT. Assuming that the MSL pressure is 1013.25 hPa the true altitude of an aircraft would actually be higher than the indicated altitude. The layer between 16000 and 18000 FT is absolutely unstable |
| The temperature at 10000 FT is in agreement with the temperature in the ICAO Standard Atmosphere. |
