Etymology: From Middle English floteren, from Old English floterian, flotorian (“to float about, flutter”), from Proto-Germanic *flutrōną, frequentative of Proto-Germanic *flutōną (“to float”), equivalent to float + -er (frequentative suffix). Cognate with West Frisian flodderje (“to flutter, beat”), Dutch flodderen (“to flutter, wave”), Low German fluttern, fluddern (“to flutter”), German flittern (“to sparkle, glitter”). More at float.

gloss: An extremely dangerous divergent oscillation caused by a positive feedback loop between the elastic deformation of an object and the aerodynamic forces acting on it, potentially resulting in rapid structural failure.
pos: noun
tags: uncountable
examples: The possibility was studied that there might be some unknown phenomenon at work that could cause a reduction in structural stiffness with age. Such a reduction in stiffness could result in a reduced flutter speed and lead to flutter. In 2004, Airbus conducted GVT in support of its MRTT program. The testing was conducted on an aged A310 aircraft (MSN 523) that had accumulated over 28 000 flight hours. This test aircraft had the same design of VTP and rudder as the occurrence aircraft. GVT results found that fin bending and rudder rotation frequencies of the MRTT test aircraft were consistent with those obtained during the original A310-300 certification. No indication was found to suggest that stiffness had reduced with age.
gloss: A small bet or risky investment.
