I . Describe the difference between wind shear and turbulence - CORRECT ANSWER-• Wind shear may or may not have turbulence, it occurs with different winds at different altitudes, usually within 2,000' AGL • Turbulence may not always mean wind shear I . Explain why space weather is a concern to aviation - CORRECT ANSWER-• Radiation exposure on polar flight routes • Navigation errors on GPS • Communication blackouts, especially on polar routes • Satellite outages 10. Identify t...

Thunderstorms which generally produce the most intense hazard to aircraft are? Squall line thunderstorms What are the processes by which moisture is added to unsaturated air? Evaporation and sublimation Why is frost considered hazardous to flight? Frost spoils the smooth flow of air over the wings, and therefore decreases the lift capability of an aircraft Clouds, fog, or dew will always form when Water vapor condenses Clouds are divided into four families according to their Height range ...
