Wind Shear

Question 1

When should a pilot consider the possibility of wind shear?

Answer 1

With either a wind shift or a wind a speed gradient at any level in the atmosphere.

Question 2

What is an important characteristic of wind shear?

Answer 2

It may be associated with either a wind shift or a wind speed gradient at any level in the atmosphere

Question 3

Which is a characteristic of low-level wind shear as it relates to frontal activity?

Answer 3

With a warm front, the most critical period is before the front passes the airport.

Question 4

When passing though an abrupt wind shear which involves a shift from a tailwind to a headwind, what power management would normally be required to maintain a constant indicated airspeed and ILS glide slope?

Answer 4

Lower than normal power initially, followed by a further decrease as the wind shear is encountered, then an increase.

Question 5

While flying a 3* glide slope, a constant tailwind shears to a calm wind. Which conditions should the pilot expect?

Answer 5

Airspeed and pitch attitude increase and there is a tendency to go above glide slope.

Question 6

Thrust is managed to maintain IAS, and glide slope is being flow. What characteristics should be observed when a headwind shears to be a constant tailwind?

Answer 6

PITCH ATTITUDE: Decreases; REQUIRED THRUST: Increased, then reduced; VERTICAL SPEED: Increases; IAS: Decreases, then increase to approach speed.

Question 7

When a climb or descent through an inversion or wind-shear zone is being performed, the pilot should be alert for which of the following change in the airplane performance?

Answer 7

A sudden change in airspeed.

Question 8

What can be expected upon arrival with reported clear skies and light winds at the surface, and winds reported as 25 knots gusting to 30 knots between 2,000 and 2,500 feet?

Answer 8

Wind shear

Question 9

If an aircraft on final approach and on glide slope encounters a sudden change from 20 knots tailwind to 20 knots headwind, the pilot should be ready to correct for

Answer 9

increased airspeed and a tendency to go above glide slope.

Question 10

While established on the ILS glideslope, a tailwind shifts to a headwind. If no control adjustments are made, this would result in

Answer 10

a decrease in descent rate.
