Question

Describe decreased performance wind shear and the hazard associated?

a) No wind -> Tailwind
b) Headwind -> No wind or Tailwind
c) Loss of lift, airspeed. Increased Rate of Descent. Could result in undershoot or stall.
d) Increased lift, decreased airspeed. Reduced Rate of Descent. Potential for overperformance.

Answer 1

Decreased performance wind shear refers to the phenomenon where the wind decreases the performance of an aircraft. It can lead to hazards such as loss of lift, increased rate of descent, undershooting, and stalling.

Step-by-step explanation:

Decreased performance wind shear refers to the phenomenon where the wind decreases the performance of an aircraft by affecting its speed and lift. When an aircraft experiences decreased performance wind shear, it can lead to a hazardous situation.

One hazard associated with decreased performance wind shear is the loss of lift and airspeed. This can result in an increased rate of descent, which can lead to the aircraft undershooting its intended landing point. Additionally, decreased performance wind shear can cause an aircraft to stall, which is a dangerous situation that can lead to a loss of control.

On the other hand, increased performance wind shear, where there is increased lift and decreased airspeed, can also be hazardous as it can lead to an overperformance situation, where the aircraft has more lift than necessary and a reduced rate of descent.
