During an abrupt wind shear, what initial power adjustment is typically required to maintain indicated airspeed?

In the event of an abrupt wind shear, the initial response to maintain indicated airspeed typically requires a higher than normal power setting. Wind shear can dramatically alter the aircraft's performance characteristics, affecting lift and drag. When encountering a sudden increase in headwind or a decrease in tailwind, the aircraft may experience a loss of airspeed and potential lift, leading to a risk of stall if not properly managed.

By applying higher than normal power, the pilot can counteract the effects of the wind shear, allowing the aircraft to maintain the required airspeed. This adjustment helps to ensure that the wings generate enough lift to keep the aircraft safely in the air, while also facilitating a more controlled response to the changing conditions.

Other options do not address the necessary performance adjustments under these circumstances. For instance, lower power settings or power cutoffs could result in insufficient thrust, leading to further loss of airspeed and potentially compromising safety. Maintaining constant power in this scenario would not account for the dynamic changes created by wind shears, which generally dictate an adjustment to power settings to ensure stability and performance.
