What is the maximum wind shear pilots should be aware of during approach?

The maximum wind shear that pilots should be aware of during approach in the CRJ 200 is 45 knots. Wind shear refers to the rapid change in wind speed or direction at different altitudes, which can pose significant challenges during critical phases of flight like approach and landing.

A wind shear condition of 45 knots signifies that the aircraft may experience a sudden increase or decrease in airspeed, which can lead to an unexpected altitude change or control issues. Understanding this limitation is vital for ensuring a safe approach and landing, as the flight crew needs to be prepared to counteract such disturbances effectively.

While other options indicate higher values, the 45 knots threshold is defined in the aircraft's operating limitations to promote safety and ensure pilots adhere to best practices in managing wind shear conditions during flight.
