ATSC 231 - BLOCK 3 | LESSON 1-3 (F.R) EXAM REVIEW QUESTIONS AND ANSWERS, GRADED A+ What are hazards cause by turbulence? - --Loss of control -Airframe Damage -Passenger Safety/Comfort What type of operation suffers from the greater frequency of turbulence accidents? - -Part 121 Average annual number of injuries as a result from turbulence... - -58 injuries per year. (3 fatalities in the past 30 years) Turbulence Definitions (2) - -Aviation: -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: -Irregular fluctuations occurring in fluid motions Factors that determine the transition from laminar to turbulent flow - -Wind Speed Surface Roughness Air Density Stability Viscosity +other factors Two types of turbulent flow - -1. Wave - regular oscillation of wind. 2. Eddies - Vortices embedded in the mean wind flow. They can be vertical/horizontal. In which scale are aircraft affected? - -Microscale What is the critical range for the Eddies? - -50-1500ft Factors that determine lift - --Coefficient of Lift -Air Density -Air Speed -Wing Area Load Factor - -Ratio of the total air load acting on an aircraft to the gross weight of the aircraft. Factors that affect load factor - -Gusts Airspeed Wing Loading Wing Loading - -Ratio of weight of aircraft to wing surfa
