ATSC 231 Block 5 Questions with Complete Solutions (Latest 2025) Non Convective Wind Shear - Correct Answers ✅Windshear that is not associated with convective clouds Low-Level Wind Shear (LLWS) - Correct Answers ✅Wind Shear That Occurs Below 2,000 ft AGL Along The Final Approach or Departure Corridor Severe Wind Shear - Correct Answers ✅D IAS > 15 kts D VSI > 500 fpm Windshear accidents Statistics - Correct Answers ✅37 total, mainly approach, landing,takeoff, 35 in part 91, 2 in Part 135 none in Part 121 Wind Shear - Correct Answers ✅Change in wind speed and/or direction over some distance NWS forecasts for Convective Shear - Correct Answers ✅False LLWS AWC Classification for Non Convective Vertical Shear - Correct Answers ✅One or More Pirep LLWS within 2000 ft AGL Gain or Loss of 20 kts IAS 1 / 3
ATSC 231 Block 5 Questions with Complete Solutions (Latest 2025) WInd shear Criteria for urgent Pilot Reports - Correct Answers ✅Classify LLWS Pireps as UUA if the pilot reports air speed fluctuations of 10 kts or More or if airspeed fluctuation is not reported classify Pireps as UUA Decreasing Headwind - Correct Answers ✅On approach the wind decreases as you get closer to the ground, Departure the Headwind decreases the higher you climb Increasing Headwind - Correct Answers ✅On Approach, the Headwind increases in strength closer to the ground, Departure the Headwind Increases the higher you climb Decreasing Tailwind - Correct Answers ✅The lower to the ground on approach the tailwind decreases, the higher you climb on departure the wind decreases Increasing Tailwind - Correct Answers ✅When on Approach the closer to the ground the stronger the tailwind gets. On departure, the higher you climb the stronger the tailwind gets Performance Increasing - Correct Answers ✅Gain in IAS - Increased in ROC or decreased ROD Increasing Headwind, Decreasing Tailwind 2 / 3
ATSC 231 Block 5 Questions with Complete Solutions (Latest 2025) Performance Decreasing - Correct Answers ✅- Loss in IAS - Increased in ROD or decreased ROC Decreased Headwind, Increased Tailwind WIndshear group (WS) - Correct Answers ✅The first 3 numbers after WS is altitude agl the numbers after the slash are the winds with respect to wind shear Ex. WS015/26055KT Temp inversion Characteristics - Correct Answers ✅Surface to 2,000 ft AGL Strongest under high pressure systems Wind - Calm or Light below inversion, Stronger Aloft Light to Moderate Shear If it is stronger than criteria WS group gets put in TAF Low Level Jet (LLJ) - Correct Answers ✅A jetstream that is typically found in the lower 2-3 KM (6,000-9,000ft) of the troposphere. At night sometimes called a nocturnal jet.Common in US Great Plains • Caused by - Cooling of terrain (25 - 50 kts) • Summertime • Southerly wind - Cyclone induced (50 - 75 kts) Surface Friction - Correct Answers ✅Windshear that results from air flowing over the earth's surface
