Theory of Flight

What is NOT one of the four aerodynamic forces?

• Lift

• Drag

• Thrust

• Moment

Which aerodynamic force is known as "the resistance of air"?

• Thrust

• Weight

• Drag

• Lift

Which principle explains how an airplane flies?

• Fizeau's Principal

• Bernoulli's Principal

• Pascals Law

• Schrodinger's Principal

Which part of the airplane creates the lift?

• Rudder

• Wing

• Stabilizer

• Flaps

What are the primary flight controls for an aircraft?

• Wings, propeller, tail

• Propeller, fuselage, ailerons

• Elevator, ailerons, rudder

• Propellor, Flaps, ailerons

The type of drag, which associated with the shape of aircraft is:

• Skin Friction Drag

• Form Drag

• Interference Drag

• Induced Drag

The angle between RAF & Chord line called:

• Incidence Angle

• AOA

• Stall Angle

• Wash-out Angle

The axis that extends from Nose section to Tail section of an aircraft is called:

• Lateral Axis

• Chord-wise Axis

• Longitudinal Axis

• Vertical Axis

The point where the lift resultant is concentrated called:

• Center of Gravity

• Center of Pressure

• Center of Dynamic Velocity

• Dynamic Viscosity

One of the following is not considered as a factor of generating lift:

• Airfoil Shape

• Air Velocity

• Air Temperature

• Air Density
