3-5 Thunderstorms

  1. DESCRIBE the hazards associated with thunderstorms
    • H - Hail
    • I - Icing
    • M - Microburst
    • E - Extreme Turbulence
    • L - Lightning
    • T - Tornados
  2. DESCRIBE the requirements associated with thunderstorms
    • M - Moisture
    • U - Unstable Air
    • L - Lifting Action
    • B - Building through freezing layer
  3. DESCRIBE the signs and hazards associated with microbursts
    • Localized downward flow of 2000-6000 feet per minute
    • Outflow produces wind shear of 20-200kts
    • .25 to 2.5 miles wide
    • Emanates from cumuliform and convective clouds, not a thunderstorm
    • VISUAL CUES: virga, rain shafts diverging from core of storm, roll clouds, extreme lightning
  4. EXPLAIN how radar can aid a pilot when flying in the vicinity of thunderstorms
    • Location and intensities can be determined
    • Used as avoidance, not penetration tool
  5. DESCRIBE the recommended techniques for avoiding thunderstorm hazards
    • C - Circumnavigate, stay 20 mi out
    • O - fly OVER top, 1000ft per every 10kts
    • U - fly UNDER base layer, fly bottom 1/3 from surface¬†
    • T - fly THROUGH, lower 1/3 of storm, 4000-6000AGL
