Lessons 1-2 Review Flashcards
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
What time fuel can be substituted for an aircraft if the recommended octane is not available
The next higher octane aviation gas
In an aircraft acquainted with a constant speed propeller and I normally aspirated engine, which procedure would be used to avoid placing undue stress on the engine components
Whenpower has been increased increase the RPM before increasing the manifold pressure.
The main purpose of the mixture control is to
Adjust the fuel flow to obtain the proper air/fuel ratio
Which statement is true regarding the effect of the application of carburetor heat
It reduces the density of air entering the carburetor, thus enriching the fuel/air mixture.
What will occur if no leaning is made with the mixture control as the flight altitude increases?
The density of air entering the carburetor decreases and the amount of fuel remains constant
The term coordinator provides an indication of
The movement of an airplane about the yaw and Roll axes
To receive accurate indications during flight from a heading indicator the instrument must be
Periodically realigned with the magnetic compass as the Gyro processes
In the northern hemisphere, a magnetic compass will normally indicate a turn towards the north if
An aircraft is accelerated while on an east or west heading
Deviation in a magnetic compass is caused by
Magnetic Fields within the airplane distorting the lines of magnetic force
In the northern hemisphere a magnetic compass will normally indicate initially a turn towards the east if
I left turn is entered from the north heading
How do variations in temperature affect the altimeter
Pressure levels are raised on warm days and indicated altitude is lower than the true altitude
If it is necessary to set the altimeter from 29.15 to 29.85, what change is made on the indicated altitude
700 foot increase
The pitot system provides impact pressure for only the
Airspeed indicator
Which V – speed represents maneuvering speed?
V(A)
