ATSC 231 Block 5 Lesson Objectives
(Final Prep) Question and answers
correctly solved
How has wind shear impacted weather accidents under Part 121 operation? -
correct answer ✔Wind Shear has a very small percentage of weather related
accidents
How has wind shear impacted Part 135 weather accidents? - correct answer
✔Wind shear has a very small impact. Wind alone is 25% of accidents
though.
Wind shear impact on Part 91 operation - correct answer ✔Wind shear
small, wind alone is the biggest.
Wind shear definition - correct answer ✔Change in speed and/or direction
over distance
What is shear gradient? - correct answer ✔Change in wind/change in
distance
What is considered severe wind shear? - correct answer ✔IAS> 15 knots
VSI> 500 FPM
What is convective wind shear? - correct answer ✔Wind shear resulting from
convective clouds
What is low level wind shear? - correct answer ✔Occurs below 2,000 AGL
, Large change in wind over short distance
Hazard on Final approach/departure
How is performance affected with a decreasing headwind on Approach? -
correct answer ✔Performance decrease
Loss of indicated airspeed
Increased rate of descent
How is performance affected with a decreasing headwind on departure? -
correct answer ✔Performance Decrease
Loss of indicated airspeed
decreased rate of climb
How is performance affected with an increasing headwind on approach? -
correct answer ✔Performance increase
Gain of Indicated airspeed
Decreased rate of descent
How is performance affected with an increasing headwind on departure? -
correct answer ✔Performance increase
Gain of IAS
Increased rate of climb
How is performance affected on approach with a decreasing tailwind? -
correct answer ✔performance increases
Gain of IAS
Decreased rate of descent
