Aileron Elevator Rudder Flap

Question 3 of 12

What is the term for the angle between the wing chord and the relative wind?

Dihedral Angle Angle of Attack Sweep Angle Angle of Incidence

Question 4 of 12

What is the purpose of winglets?

To increase drag To decrease lift To reduce induced drag To increase fuel consumption

Question 5 of 12

What phenomenon causes a stall?

Insufficient thrust Excessive airspeed Low engine RPM Critical angle of attack exceeded

Question 6 of 12

What type of drag is caused by the shape of the aircraft?

Form Drag Skin Friction Drag Interference Drag Induced Drag

Question 7 of 12

The

Bernoulli's principle

states that:

Pressure is constant regardless of speed Pressure decreases with increasing speed Pressure increases with increasing speed Pressure is directly proportional to density

Question 8 of 12

What is the effect of ground effect on lift and drag?

Increases both lift and drag Decreases both lift and drag Increases lift and decreases drag Decreases lift and increases drag

Question 9 of 12

What is the function of a leading-edge slat?

To increase airspeed To increase drag To decrease stall speed To reduce fuel consumption

Question 10 of 12

What aerodynamic effect causes a spinning aircraft to resist stopping the spin?

Adverse Yaw Coriolis Effect Autorotation Dutch Roll
