ATSC 231 Test 3 Questions and Answers 100% Pass

ATSC 231 Test 3 Questions and Answers 100% Pass 3 hazards of turbulence - • Loss of Control • Airframe Damage • Passenger Comfort/Safety Which type of aircraft have the most accidents as a result of turbulence? - Part 121 Annual turbulence injuries - 58 injuries Aircraft 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. Turbulence Meteorology - Meteorological Turbulence - Irregular fluctuations occurring in fluid motions What factors affect the transition from laminar to turbulent flow - - Wind speed - Surface Roughness - Air Density - Stability - Viscosity - Other factors Two Types of turbulent flow - - Wave 2 | P a g e Emily Charlene © 2025, All Rights Reserved. - Eddies or Vortices Characteristics of waves - - Regular oscillation of wind Characteristics of eddies - - Eddies are vortices embedded in the mean wind flow What scale of turbulence affects aircraft? - Microscale Critical Eddie size for aircraft - 50 to 1500 ft What is the relationship between AOA and lift - Lift increases until critical AOA is reached which causes a stall Load Factor - - Ratio of the total air load acting on an aircraft to the gross weight of the aircraft What affects load factor in turbulence - Vertical Acceleration increases it How does airspeed affect an aircrafts susceptibility to turbulence - Faster you are moving the stronger the load factor Wing Loading - - Ratio of weight of aircraft to wing surface area What does high wing loading lead to? - More protection from turbulence magnitude of turbulence measured in what - G's Gusts measured in what - FPM Newton's Second Law - F=ma maneuver speed - speed above which it is unwise to make full application of any single flight control as it may generate a force greater than the aircraft's structural limitations Flight Load factor - The highest load factor that can be expected in normal operations Design Load Factor - 1.5 greater than Flight Load Factor - Protection against unexpected conditions 3 | P a g e Emily Charlene © 2025, All Rights Reserved. Convective Turbulence - Turbulence that results from rising currents of air Types of convection - • Forced Convection - Air becomes unstable after it is forced to rise • Free Convection - Air rises because it is initially unstable 7 8 5 Convection • Dry Convection - Rising air remains unsaturated • Moist Convection - Rising air reaches saturation - Produces cloud What is a thermal - rising current of warm air Characteristics of a thermal - Vertical Velocity - Updraft • 200 to
