What are the properties of air?
21% oxygen
78% nitrogen
1% other gasses
Where does the troposphere start and where does it extend to?
Starts at earth and extends 8-14.5 km
What does the troposphere have in terms of weather?
All weather types
What aircraft fly within the troposphere?
Most light aircraft and turboprops
Where does the stratosphere start and how high does it extend?
Starts above troposphere and extends 50km
What protective section does the stratosphere contain?
Ozone layer
In the stratosphere what happens with height and temperature?
As height rises temperature falls
What are the 3 atmosphere layers that aircraft operate in?
Troposphere
Tropopause
Stratosphere
What is good about the tropopause for aircraft?
Less air resistance so higher fuel efficiency.
