In the TAF provided, what is the forecast wind shear?

1. 5 feet AGL from 270° at 50 KT.

2. 50 feet AGL from 270° at 50 KT.

3. 500 feet AGL from 270° at 50 KT.

4. 1,000 feet AGL from 270° at 50 KT.

The correct answer is: 500 feet AGL from 270° at 50 KT.

The correct answer indicates that wind shear is forecasted at 500 feet AGL, from 270° at a rate of 50 knots. Wind shear is defined as a change in wind speed and/or direction with altitude. When interpreting the TAF (Terminal Aerodrome Forecast), a height of 500 feet AGL is often associated with critical phases of flight, such as departure and approach, making it a key altitude for pilots to consider during operations. Forecasting wind shear at this altitude allows pilots to anticipate potentially hazardous conditions that could affect their aircraft's performance, particularly during takeoff or landing. A wind shear of 50 KT at this altitude indicates a significant change in wind characteristics, which could lead to turbulence or loss of control if not managed properly. Understanding wind shear is crucial for operational safety, and 500 feet AGL is a common threshold for where such conditions can be most impactful, making this forecast information vital for maximizing safety during flight operations.
