What happens to power requirements during decreased performance wind shear for maintaining a proper glide slope?

• A. More power is needed
• B. No change in power needed
• C. Less power is needed
• D. Power is increased dramatically

Answer: (A)

During periods of decreased performance wind shear, the power requirements for maintaining a proper glide slope increase. This phenomenon occurs because wind shear can lead to variations in wind speed and direction which, in turn, affect the lift and drag characteristics of the aircraft. When experiencing a headwind or diminishing headwind due to wind shear, the effective speed of the aircraft can be adversely impacted, requiring the pilot to apply additional power to maintain the desired glide slope. The increased power helps compensate for the loss of lift caused by reduced groundspeed, ensuring the aircraft can ascend or descend appropriately without deviating from the glide path. Understanding this phenomenon is crucial for pilots, as it helps them anticipate power adjustments needed under changing wind conditions during approaches or landings.
