ATSC 231 Block 3 Objectives
(Turbulence) Exam Questions and
Answers 100% Pass

What are the three hazards resulting from turbulence? - ✔✔Loss of Control, Airframe Damage, Passenger

Comfort/Safety


What type of operation does turbulence produce the greatest frequency of accidents? - ✔✔Part 121


What is the average annual number of injuries caused by turbulence? - ✔✔58


Aviation definition of turbulence - ✔✔Irregular motion of an aircraft in flight, especially when

characterized by rapid up-and-down motion, caused by a rapid variations of atmospheric wind velocities


Meteorological definition of turbulence - ✔✔Irregular fluctuations occurring in fluid motions


What are the factors that determine the transition from laminar to turbulent flow - ✔✔Primarily Wind

speed and surface roughness, but also density, stability, viscosity, and other factors


What are two types of turbulent flow - ✔✔Waves, Eddies/Vortices


What are the characteristics of waves? - ✔✔Regular oscillation of wind, you might not even feel

turbulence if in a wave


What are the characteristics of eddies? - ✔✔Vortices embedded in the mean wind flow. Eddies are what

cause gusts


What scale does turbulence the effect aircraft occur on? - ✔✔Microscale

What factors affect lift? - ✔✔Coefficient of Lift, Air density, air speed, wing area


How does the coefficient of lift changes with angle of attack - ✔✔Increases linearly with increasing AOA

until stall


What is load factor? - ✔✔Ratio of the total air load acting on an aircraft to the gross weight of the aircraft


What factors affect load factor in turbulence - ✔✔Gusts, Airspeed, Wing Loading


How do vertical gusts affect load factor - ✔✔Change in AOA and change of relative wind. Change in lift,

change in load factor. Aircraft may stall or exceed a limitation


How does airspeed affect load factor - ✔✔Determines additional lift created by gust, slower is better.

Maneuvering speed


What is wing loading - ✔✔Ratio of weight of aircraft to wing surface area


How does wing loading affect load factor - ✔✔Gust load factor inversely proportional to wing loading,

smooth ride with high wing loading


What are the various units that are used to describe the magnitude of turbulence - ✔✔Feet per minute,

G's, meters squared per second squared, Eddy dissipation rate


Energy cascades from smaller eddies to larges ones in the atmosphere - ✔✔FALSE


Critical eddy size to affect aircraft - ✔✔50ft - 1500ft


What are convective turbulence - ✔✔Turbulence that results from rising currents of air


Characteristics of thermals - ✔✔Rising mass of buoyant air


Two models, plume (rising, still attached to surface) or bubble (rising, expands as it rises, not attached to

surface)
