wingbeat
Single wing cycle
A wingbeat is one complete up-and-down cycle of a wing in flight.
The term appears in discussions of birds, insects, and aircraft: A hummingbird's wingbeat can exceed eighty times per second.
Wingbeat frequency and pattern help identify species and determine flight efficiency.
