During what phase of flight should you be especially aware of wind shear?

The descent and approach phase is critical for awareness of wind shear because this is when an aircraft is transitioning from high altitude to landing. At lower altitudes, particularly near the ground, variations in wind speed and direction can occur more frequently due to factors such as terrain, temperature inversions, and the presence of obstacles. These wind shear effects can lead to sudden changes in vertical speed, which can be dangerous during the crucial phases of landing, requiring precise control of the aircraft.

During descent and approach, pilots are often operating at slower speeds and reduced altitudes, making the aircraft more susceptible to the effects of wind shear. Recognizing and responding appropriately to wind shear during this phase is vital for maintaining safe control of the aircraft, avoiding loss of altitude, or even stall scenarios. Other phases, such as climb, cruise, or pre-takeoff, generally have less immediate proximity to the ground, where wind shear might manifest most critically.
