Is this correct? Lee Whitt Lee, Never heard of the term. Would appreciate any verified use of term for my oddities file. I'll shoot it into the newsgroups for a check. "Michael A. Pilla" <mpilla@mitre.org> Subject: Re: wolferdale Gene, You're probably referring to "Wifferdill" or "Whiferdill"; I've seen both spellings. It is the English term for either an Immelman turn or a Chandelle turn, IIRC.I.e., a one-half loop followed by a roll at the top (180o) for the Immelman and a sharp pull up, rolling, maximum performance turn (also 180o) for the Chandelle. I wish I had my flight maneuver manuals with me; could give you the precise definition. Michael Pilla Could it be "whifferdill"? I used to fly with an ex-usaf cfi, and he used that term to describe any of several "playing-around" maneuvers (wing-overs, steep turns, etc.) Written by Gene Whitt Flight Training Article Library | Back To 4VFR.COM
