Arm span or reach (sometimes referred to as wingspan, or spelled armspan) is the physical measurement of the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90° angle. The arm span measurement is usually very close to the person's height.
Based on proportions identified by Vitruvius, the drawing shows a man where the arm span is equal to the height, giving an ape index of 1. Ape index , ape factor , [ 1 ] or gorilla index is slang or jargon used to describe a measure of the ratio of an individual's arm span relative to their height.
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of 60.93 metres (199 ft 11 in), [ 1 ] and a wandering albatross ( Diomedea exulans ) caught in 1965 had a wingspan of 3.63 metres (11 ft 11 in), the official record for a living bird.
5.5 m – height of a Baluchitherium, the largest land mammal ever lived; 6.5 m – wingspan of Argentavis, the largest flying bird known; 6.7 m – length of a Microchaetus rappi; 7.4 m – wingspan of Pelagornis, the bird with longest wingspan ever. [123] 7.5 m – approximate length of the human gastrointestinal tract
A sectional chart is a two-sided chart created from a Lambert Conformal Conic Projection [1] with two defined standard parallels. The scale is 1:500,000, with a contour interval of 500 feet. The size of each sectional is designed to be "arm's width" when completely unfolded.
The table contains a list of the largest birds living on this planet by wingspan, at maximum, assumed to be reliable by experts and verified records, at least 3 m (9 ft 10 in). Rank Image
An ASH 31 glider with very high aspect ratio (AR=33.5) and lift-to-drag ratio (L/D=56). In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord.It is equal to the square of the wingspan divided by the wing area.
This wingspan is similar to that of the larger Boeing 747-200, but with 35% less wing area. [73] [74] The A340 uses a modified A320 glass cockpit, with side-stick controls instead of a conventional yoke. The main instrument panel is dominated by six displays, cathode-ray tube monitors initially then liquid crystal displays. [68]
