Detecting and Reporting Wind Shear and Microbursts
Operating aircraft during volatile wind shifts are critical environmental factors to successfully navigating a safe landing or take off. A strong headwind causes the pilot to push the aircraft nose down to effect the proper glide slope on final approach. When under wind shear or microburst conditions, in an instant that headwind can switch to an equally strong tail wind causing a dangerous loss of air speed. Having an early warning system that alerts the pilot of these dangerous conditions is essential for the safe operation of your airfield.
