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.
The root box is estimated from a measurement of the wing width at the base (the root chord) and the difference between the wingspan and two times the extent of a single wing. [10] Alternatively, the total wing area can be estimated using the wingspan, wing length, and wing width and assuming simple geometric figures for the shape of the wings. [11]
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.
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.
One notable NBA player with an ape index below 1 is Desmond Bane, whose wingspan of 6' 4" is less than his height of 6' 5"; he has been nicknamed "T-Rex" for this reason. [11] Despite this perceived deficiency, Bane has become a quality player since being selected 30th overall by the Memphis Grizzlies in the 2020 NBA draft out of TCU.
Wingspan: 44 ft 1 + 1 ⁄ 2 in (13.45 m) Height: 11 ft 5 + 1 ⁄ 2 in (3.49 m) Wing area: 225.8 sq ft (20.98 m 2) Empty weight: 4,368 lb (1,981 kg)
Most importantly, the maximum lift-to-drag ratio is independent of the weight of the aircraft, the area of the wing, or the wing loading. It can be shown that two main drivers of maximum lift-to-drag ratio for a fixed wing aircraft are wingspan and total wetted area. One method for estimating the zero-lift drag coefficient of an aircraft is the ...
The wingspan of the great potoo and the oilbird can be more than 1 m (3.3 ft), the largest of the order. [69] [70] The largest species of the nightjar family, the great eared nightjar (Eurostopodus macrotis) of East Asia, is of smaller proportions. Great eared nightjars can reach 150 g (0.33 lb) in weight and 41 cm (16 in) in height. [71]
