Aerodynamics Review

According to the Bernoulli Principle, when a fluid's speed increases, the pressure

• 
  stays the same

• 
  decreases

• 
  increases

For lift to occur, which side of the wing needs to have low pressure?

• Front

• Back

• Top

• Bottom

How are a plane's wing flaps positioned during landing?

• 
  flat and straight (retracted)

• 
  curved downward

  (fully extended)

• curved upward

When an aircraft's speed increases, drag on the aircraft generally ___.

• 
  increases

• 
  

  decreases

• 
  stays the same

What happens to the speed of a fluid when it is forced into a small opening?

• 
  there is no change

• 
  it decreases

• 
  It increases

A perfectly flat wing is able to easily create enough lift to fly a plane.

• True

• False

If the wing stalls, what is the most important action to recover?

• 
  Apply back pressure.

• 
  Let go of the controls.

• 
  Reduce the angle of attack to less than its critical value.

The chord line is an imaginary line connecting which of the following?

• 
  Wing tip to wing tip

• 
  Wing root with wing tip

• 
  Leading edge to the trailing edge of the wing

• Nose to tail of the aircraft

Extending or retracting flaps changes the wing's and characteristics.

• 
  weight, thrust

• 
  lift, drag

• 
  thrust, drag

______ are used to increase the lift and the drag at slower speeds (takeoff and landing)

• rudders

• flaps

• ailerons
