Yes -- windshear will appear as a sudden decrease (or increase) in airspeed, which manifests itself as reduced (sometimes to negative) ROC. It takes thrust to overcome a windshear. 2. And does windshear show up as a distinct feature in the flight weather radar? No -- radar detects only precipitation or other, solid, objects. A link to any site that explains the mechanics of a windshear would be welcome. Ramapriya

Most of those systems work by measuring wind direction and velocity at various points around the airport and comparing them. If there is a substantial difference between two or more monitoring points, a wind shear alert is issued. John Galban=====N4BQ (PA28-180)
