ANN's Daily Aero-Term (02.15.13): ETOPS

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.

ETOPS

Extended Range Operations with Twin-engine airplanes. An airplane flight operation during which a portion of the flight is conducted beyond 60  minutes and up to 180 minutes from an adequate airport for turbine-engine-powered airplanes with two engines. 
 
This distance is determined using an approved one-engine inoperative cruise speed under standard atmospheric conditions in still air.
