Questions With Correct Answers

Relative Wind (RW) - CORRECT ANSWER✔✔-the direction from which the airflow
| | | | | | | | | | |


hits the wing; directly opposite the aircraft flight path
| | | | | | | |




Angle of Attack (AoA) - CORRECT ANSWER✔✔-the angle between the extended
| | | | | | | | | | |


chord line and the relative wind.
| | | | |




Stall Facts - CORRECT ANSWER✔✔-•For a given airfoil, a stall always occurs at the
| | | | | | | | | | | | |


same angle of attack
| | | |




| - Airspeed, weight and attitude irrelevant
| | | | |




•Stall characteristics vary with different airfoil shapes and wing planforms
| | | | | | | | |




| -Training airplanes usually have gradual stall
| | | | | |




| patterns
•Recovery procedures same for all airplanes: | | | | |




| -Maximum power |




| -Reduce angle of attack | | |




| -Roll wings level| |




Center of Gravity(CG) - CORRECT ANSWER✔✔-an airplane's balance point, where
| | | | | | | | | |


all weight is considered to be concentrated
| | | | | |




| -Airplane pivots about CG in all 3 dimensions
| | | | | | |

,Three Axes of Flight - CORRECT ANSWER✔✔-1.Longitudinal - "roll axis" - ailerons
| | | | | | | | | | |




2.Lateral - "pitch axis" - elevator
| | | | |




3.Vertical - "yaw axis" - rudder | | | | |




Level Flight - CORRECT ANSWER✔✔-Constant Speed Level Flight:
| | | | | | |




| •Thrust = Drag, Lift = Weight,
| | | | | |




•To accelerate:
|




| •Thrust > Drag, Lift = Weight
| | | | |




Engine Torque - CORRECT ANSWER✔✔-•Caused by rotation of propeller
| | | | | | | |




| -Propeller turns clockwise | |




| -Airplane wants to roll | | | |




| counterclockwise
•Proportional to RPM | |




•The effect of torque increases in direct proportion
| | | | | | | |




| to the engine power, airspeed, and airplane
| | | | | | |




| attitude. If the power setting is high, the airspeed
| | | | | | | | |




| slow, and the angle of attack high, the effect of
| | | | | | | | | |




| torque is greater | |




•Anticipate need to roll right | | | |




Forward CG - CORRECT ANSWER✔✔--Stab creates more negative lift
| | | | | | | |

, -Wing tasked to provide more positive lift
| | | | | |




-Increased induced drag from both stab and wing
| | | | | | |




-However, very stable (easy to control) airplane
| | | | | |




Aft CG - CORRECT ANSWER✔✔--Stab creates less negative lift
| | | | | | | |




-Wing relieved of some positive lift requirement
| | | | | | |




-Decreased induced drag from both stab and | | | | | | |




| wing
-However, very unstable airplane | | |




Spin Aerodynamics - CORRECT ANSWER✔✔-•Both wings are stalled!
| | | | | | |




•Outboard wing not stalled as badly | | | | |




| -Creates more lift than inboard
| | | |




| -Perpetuates rotation |




Climb Speeds - CORRECT ANSWER✔✔-•Best Angle (VX) - for obstacle clearance
| | | | | | | | | |




•Best Rate (VY) - fastest to altitude and cruise
| | | | | | | |




Wake Turbulence - CORRECT ANSWER✔✔-•Source is wingtip vortices
| | | | | | |




| -High pressure air below curves around tip
| | | | | | |




| toward low pressure air on top of wing
| | | | | | |




•Intensity of vortices proportional to amount of lift
| | | | | | | |




| & induced drag being produced by a wing
| | | | | | |
