Module 8. Basic aerodynamics

An undercarriage leg in flight produces 3 lbs of drag at 100kts. If speed is increased to 200kts the drag would be

  • 12 lbs.
  • 9 lbs.
  • 6 lbs.
arifadli8 asking:

how to calculate...

Module 8. Basic aerodynamics

The speed of air over a swept wing which contributes to the lift is

  • less than the aircraft speed.
  • the same as the aircraft speed.
  • more than the aircraft speed.
sauravkatwal asking:

isnt upper surface has more velocity than the relative wind?

Module 8. Basic aerodynamics

With respect to differential aileron control, which of the following is true?

  • The up going and down going ailerons both deflect to the same angle.
  • The up going Aileron moves through a smaller angle than the down going aileron.
  • The down going aileron moves through a smaller angle than the up going aileron.
sauravkatwal asking:

isnt it vice versa?

Module 8. Basic aerodynamics

If an aircraft in level flight loses engine power it will

  • pitch nose up.
  • pitch nose down.
  • maintain pitch until drag builds up.
sauravkatwal asking:

Isn't it should temporarily nose up before eventually going nose down since CoP is behind CoG, and with no thrust CoP decreases the lift(behind CoG) causing nose up?

Module 8. Basic aerodynamics

An aircraft left wing is flying low. The aileron trimmer control to the left aileron trim tab in the cockpit would be

  • moved up causing the left aileron to move up.
  • moved up causing the left aileron to move down.
  • moved down causing the left aileron to move down.
sauravkatwal asking:

Is this question is about STABILITY or the position of trim tab/aileron ?
