Questions and Answers

Where is Turbulence associated with Airmass Fronts most likely located?

  • At the Frontal Boundary (correct)
  • Within the Warmer Portion of the Front
  • Within the Colder Portion of the Front
  • Behind the surface position of a Cold Front, and Ahead of a Warm Front

Why is Turbulence often associated with the Top of an Inversion Layer?

  • Because of the mechanical turbulence generated by terrain near the top of the Inversion layer
  • Because of the convection currents at the top of the Inversion layer
  • Because winds blowing at the top of the Inversion layer cause turbulent eddies as they interact with the stable layer below (correct)
  • Because of the often violent updrafts and downdrafts within the Inversion

Why may Light Turbulence be detrimental to Aircraft Operations?

  • Due to distraction and making routine tasks more difficult (correct)
  • Due to the inability to read the Aircraft Instruments
  • Due to possible structural damage when flying above Va (Maneuvering Speed), but below Vno (Maximum Structural Cruising Speed)
  • Due to possible structural damage when flying below Vno (Maximum Structural Cruising Speed)

Why do Thunderstorms produce Severe and Extreme Turbulence?

<p>Because they have strong Windshear associated. (D)</p> Signup and view all the answers

What effect does Airspeed have on the way an Aircraft Reacts to Turbulence?

<p>An airplane wing is capable of producing much more lift at higher airspeeds, resulting in large changes in lift when the angle of attack changes on the wing due to a shift in the relative wind. (C)</p> Signup and view all the answers

How can a pilot avoid the most turbulent parts of the Atmosphere when the atmosphere is moist enough to form clouds due to convective lifting action?

<p>By remaining above the bases of the Cumulus clouds, and inside of the clouds themselves. (C)</p> Signup and view all the answers

How can a pilot avoid encountering turbulence associated with mountain wave activity?

What is a sign that a pilot is encountering moderate turbulence?

<p>They feel definite strain against their seatbelts, and unsecure objects become dislodged (D)</p> Signup and view all the answers

How would a pilot know they are flying in an area with low Specific Heat Capacity surfaces?

Why does a heavier aircraft react differently to turbulence compared to a lighter aircraft?

<p>Heavier Aircraft are NOT affected by Turbulence as much as Lighter Aircraft, due to their greater Inertia (D)</p> Signup and view all the answers
