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.).

| | | A mid-air collision is an aviation accident in which two or more aircraft come into contact during flight. Owing to the relatively high velocities involved and any subsequent impact on the ground or sea, very severe damage or the total destruction of at least one of the aircraft involved usually results. The potential for a mid-air collision is increased by miscommunication, mistrust, error in navigation, deviations from flight plans, and the lack of collision-avoidance systems. Although a rare occurrence due to the vastness of open space available, collisions often happen near or at airports, where large volume of aircraft and closer spacing compared to general flight is present. | | source: FAA Airplane Flying Handbook (FAA-H-8083-3A) |
