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.

Proverse Yaw

An ANN reader sent this term after reading Wednesday about Adverse Yaw. "A few years ago while doing research for a program I was developing for CAE SimuFlite, (where I work as an instructor), I discovered that there is also Proverse Yaw.
 
Proverse Yaw is yaw in the direction of the turn and occurs when an aircraft uses spoilers for roll control. The spoiler on the down side in the turn causes drag which assists the turn."

Thanks, and if you have a suggestion for and Aero Term, be sure to let us know.
