[QUOTE="Apophenia, post: 268926, member: 728"] [b]Akaflieg Berlin Aircraft Designations - 1922-Present[/b] (Akademische Fliegergruppe Berlin e.V. - Academic Aviator Group Berlin) The presentation style of Akaflieg Berlin designations varies - being shown with hyphens, without hyphens (in typical German style), with a period, and with no space at all between the 'B' and the following numeral. I have adopted the latter style since Akaflieg Berlin, itself, does not use a space. One designation anomoly appears - the A.B.4 FF light aircraft. I suspect this 'A.B.' to be a journalistic assumption. Doubtless, within Akaflieg Berlin, this aircraft was simply designated B4. From 1934-1945, Akaflieg Berlin was known as the Flugtechnische Fachgruppe. I am assuming that the 'FF' in B4 FF anticipated this name change - although the acronym for the group was usually given as 'FFG'.* ____________________________ * In full, 'FFG' was for [i]Flugtechnische Fachgruppe an der TH Berlin bei der Deutschen Versuchsanstalt für Luftfahrt e.V[/i] or the Flight Technical Group at the Technical School ([i]Technischen Hochschule[/i]) Berlin eV for the German Aviation Research Institute (e.V being for [i]eingetragener Verein[/i] or registered association). ____________________________ [b]Akaflieg Berlin Designations[/b] B1 -
