Aerodynamic for Student Pilot

The four forces acting on the airplane during flight

• Lift, Drag, Gravity, Cruise

• Climb, Descend, Turn, Yaw

• Drag, Pitch, Yaw, Roll

• Lift, Drag, Weight, Thrust

It’s caused by the separation of airflow from the wing’s upper surface. This results in a rapid decrease in lift, what definition for this statement

• Parasite Drag

• Induced Drag

• Stall

• Lift

The angle of attack is

• The angle between the chord line of the airfoil and direction of the relative wind

• The angle between the chord line of the airfoil and direction of the flight path

• The angle between the chord line of the airfoil and direction of the longitudinal axis

• The angle between the camber of the airfoil and direction of the relative wind

The angle of incidence is

• The angle between the chord line of the airfoil and direction of the relative wind

• The angle between the chord line of the airfoil and direction of the flight path

• The angle between the chord line of the airfoil and direction of the longitudinal axis

• The angle between the camber of the airfoil and direction of the relative wind

What is parasite drag

• caused by any aircraft surface

• caused by roughness of the airplane’s surfaces

• caused by wake turbulence

• caused by creating lift

What is skin friction drag

• caused by any aircraft surface

• caused by roughness of the airplane’s surfaces

• caused by creating lift

• results from the turbulent wake caused by separation of airflow from the surface of structure

Directional stability of an airplane

• Stability about an airplane’s vertical axis

• Stability about an airplane’s longitudinal axis

• Stability about an airplane’s lateral axis

Longitudinal stability of an airplane

• Stability about an airplane’s longitudinal axis

• Stability about an airplane’s lateral axis

• Stability about an airplane’s vertical axis

• Stability about an airplane’s horizontal axis
