Aviation Glossary Welcome to the Dauntless Aviation Glossary!

At Dauntless, our editorial staff maintains the web's largest unified glossary of aviation terms. This glossary is built from a combination of official, quasi-official, and proprietary sources (including original material that we develop oursselves). Uniquely, we often provide multiple definitions of a given term so that you can find that which best applies to you. In order to maximize your learning efficiency, this glossary (and similar ones for our international users) is incresingly fully integrated into our aviation learning apps, including our FAA written test prep and FAA practical test prep software and apps. If you like this glossary, you'll love them with their polished learning environments and world's best and clearest content (please do give them a try.).

Probe Heat
Probe Heat
the electrical anti-icing of the air data probes (pitot probe, static ports, angle of attack sensors, outside air temperature sensors) which are located on the outside of the forward fuselage. The failure of the probe heat system on the A330 is suspected as being a contributory factor to the loss of Air France Flight 447 over the South Atlantic in June 2009. If the probes become obstructed with ice, the flight crew can lose all altitude, airspeed and angle of attack information and the computers which receive this information will generate erroneous outputs
