Deifne the tropopause:

Hohe Tropopause 

11 km bis ca. 20 km

4 Tropoausen 

1) Polar Tropoause= 8km = -50 degrees

2) Suvtropial = 11 km = -56,5 Grad 

3) Equatorial 16km = -70 degrees

4) WInter: Artic = 6-7 km = -45 degrees

During a flight at Fl 100 from Marseille (QNH 1012 hPa) to Palma de Mallorca (QNH 1015 hPa) an aircraft remains at a constantvtrue altitude. The resonon for this is that: 

During a flight over the sea at FL 135 the True Altitude is 13'500 ft: local QNH is 1019 hPa. What information, if any, can be gaines about the air mass in which the aircraft is flying ? 

AN aircrafr is flying over teh sea at Fl 90; the true altitude is 9100 ft; local QNH is unkown. What assumption, if any, can be made about the air mass in which the aircraft is flying??

When flying at FL 180 in teh Northern Gemisphere you experience a right drift: 

What can you exceed at FL 180, when te wind is geostrophic and your true altitude is 18'000 ft?
