Aero-Terms!

Aero-Terms are designed to be a daily reminder of the terms, names, acronyms and explanations of the unique language that populates the aviation world. Aerospace, sport aviation, fixed wing, helo, you name it... it's all fair game.

Aero-Terms should serve as a quick but intriguing reminder of the terms you may use every day, or an introduction to an aspects of the Aero-World you may not yet be familiar with. ANN also encourages readers to go beyond the FMI link, and further research any intriguing terms.

Suggestions for future Aero-Terms are ALWAYS welcome, as are additions or discussion of the explanations given for each Aero-Term.

Note: This month's Aero-Terms were sent in by ANN readers throughout the year. Thanks to everyone who suggested Aero-Terms. Keep them coming!

ELT

Emergency Locator Transmitter -- A radio transmitter activated automatically by the impact of an accident or can be turned on manually if the crash force is insufficient for automatic activation (this would be preferable). Emits a warbling tone on the international emergency frequencies of 121.5 MHz, 243 MHz and (newer models) 406 MHz. ELT signals can be received by nearby FAA facilities, aircraft overhead, and search and rescue (SARSAT) satellites. One of the items in the aircraft we hope never to use.
