Forces and Aerodynamics of Flight

Match the following

• Relative Wind

• The angle at which an aircraft stalls

• Flaps

• The angle between the relative wind and the wing chord.

• Angle of Attack

• Allows the airfoil to generate more lift at slower speeds and increases drag.

• Critical Angle of Attack

• Turns the nose of the aircraft on the yaw access.

• Rudder

• The air moving across the airfoil which makes lift possible

Match the following

• Drag

• The force that propels the aircraft forward

• Weight

• The upward force that allows an aircraft to rise

• Lift

• The downward force on the aircraft caused by gravity

• Thrust

• The force that opposes the forward motion of the aircraft

Match the following

• Newton's Third Law

• I'm not superstitious, but I am a little stitious.

• Army Law

• • Everything takes longer than you think.

• Murphy's Second Law

• Every action has an equal and opposite reaction

• Daniel Bernoulli

• If it moves, salute it; if it doesn't move, pick it up; if you can't pick it up, paint it.

• Michael Scott

• Faster moving fluid as lower pressure

When are the four forces of flight in equilibrium?

• Lift=Weight

  Thrust=Drag

• Never

• While Climbing

When you are stalling the aircraft, where does the wing stall first?

• wing root

• wing tip

A full power on configuration will cause the aircraft to be in a higher pitch attitude in order to stall the aircraft.

• True

• False

Frost will affect aircraft performance and can lead to a lower stall speed because it changes the lift created by the wing.

• True

• False

What is the primary force that opposes the motion of an airplane through the air?

• Lift

• Drag

• Thrust

• Weight

Which force must be greater than weight for an airplane to take off?

• Thrust

• Drag

• Lift

• Gravity

The resistance of air pushing back against the plane acts in opposition to THRUST is called (a)  

• Drag
• Lift
• Thrust
• Gravity
