Purpose of the Program
It is important to know certain properties of the atmosphere at different altitudes, because in a real
situation these properties change greatly with vary altitudes. This program can be used to find the
temperature, pressure, speed of sound, and density of air at any altitude between 0 and 2,000,000 ft. To
address this problem the atmosphere was divided into 8 different levels. On these 8 different levels it is
known how these 4 properties behave. On all levels they are modeled using some function of altitude.
Purpose of the Program (10 pts)
This section should be a brief but complete statement of the problem being solved and the method
used to accomplish the solution. It should include address the practical value of writing the program
and solving the posed problem.
Mathematical Technique
There are known mathematical relations to the properties of the atmosphere as a function of altitude. I
pulled these relations from the flight manual [1]. In the flight manual the atmosphere is broken up into 8
different levels. At each one of these levels there is a different function of temperature and pressure. At
every level the function for the speed of sound and the density are the same. In the levels 1, 3, 4, 6, and 7
the functions for temperature and pressure are as such
= +
Temperature a bh
= (
)
Pressure c Temperature d
While as in the levels 2, 5, and 8 the functions for temperature and pressure are
=
Temperature a
