APPLICATION OF AERODYNAMICS TO SPECIFBC PROW 
OF FLYING 
While the previous chapters have presented 
the detailed parts of the general field of aero- 
dynamics, there remain various problems of 
flying which require the application of princi- 
ples from many parts of aerodynamics. The 
application of aerodynamics to these various 
problems of flying will assist the Naval Aviator 
in understanding these problems and develop- 
ing good flying techniques. 
PRIMARY CONTROL OF AIRSPEED AND 
ALTITUDE 
For the conditions of steady flight, the air- 
plane must be in equilibrium. Equilibrium 
will be achieved when there is no unbalance of 
force’or moment acting on the airplane. If it is 
assumed that the airplane is trimmed so that 
no unbalance of pitching, yawing, or rolling 
moments exists, the principal concern is for
