Gust probe

From Glossary of Meteorology

gust probe

An air velocity sensing instrument usually mounted on the front of an aircraft that resolves turbulent fluctuations in all three components relative to the aircraft.

Instruments used for this purpose include differential pressure probes, vanes, and heated wires (hot-wire anemometers). To measure the air velocity relative to the earth, the gust probe measurements must be corrected for the aircraft attitude and velocity.
