When are the 4 aerodynamic forces that act on an airplane in equilibrium?
During unaccelerated flight
The purpose of the rudder on an airplane is to
Control Yaw
Term Angle of attack is defined by
Angle between wing cord line and the relative wind
As altitude increases, stall speed does what
Remain the same regardless of altitude
What causes an airplane to pitch nose down when power is reduced and controls are not adjusted
Downwash on elevators from propellor slipstream is reduced and elevator effectiveness is reduced
What effect does increased load factor have on an airplane during an approach to a stall
Airplane will stall at a higher airspeed.
What determines longitudinal stability of an airplane
Location of the CG with respect to the center of lift
Left turning tendency of an airplane caused by the P factor is the result of
Prop descending on the right, producing more thrust than the ascending blade on the left
What is purpose of wing flaps
Enable the pilot to be able to make steeper approaches without increasing airspeed
In what flight conditions is torque affect the greatest in a single engine airplane
Low airspeed, high power, High angle of attack
What makes an airplane turn
Horizontal component of lift
As you maneuver an airplane you should realize that it can be stalled
At any airspeed and in any attitude
To counteract the effect of torque in a conventional single engine propeller driven airplane, a pilot would normally add
Right rudder pressure during the takeoff roll and while climbing with full power
To generate the same amount of lift as altitude is increased, an airplane must be flown at
A higher true airspeed for any given angle of attack
During a spin to the left, which wing(s) are stalled?
Both wings are stalled
What action can a pilot take to aid in cooking an engine that is overheated during a climb?
Reducing rage of climb and increasing airspeed
A precaution for the operation of an engine equipped with a constant speed propeller is to
Avoid high manifold pressure settings with low RPM
Filling the fuel tanks after the last flight of the day is considered a good operating procedure because this will
Prevent moisture condensation by eliminating air space in the tanks
Which condition is most favorable to the development of carburetor icing?
Temperature between 20 and 70°F and high humidity
The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as
Preignition
If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, the pilot may have been
Operating with too much power and with a mixture set too lean
If an engine continues to run after the ignition switch is turned OFF, the probable cause may be
A broken magneto ground wire
Detonation occurs in a reciprocating aircraft engine when
The unburned charge in the cylinders explodes instead of burning evenly
An abnormally high engine oil temperature indication maybe caused by
The oil level being too low
