ATSC 231 Block 5 Lesson Objectives (Final
Prep) UPDATED ACTUAL Questions and
CORRECT Answers
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
How is performance affected on departure with a decreasing tailwind? - CORRECT
ANSWER - performance increases
gain of IAS
Increased rate of climb
