For low wing-loading (e.g. an un-ballasted racing glider) this might be 55knots/100kph but with ... Aspects ratios and wing loading are combined for different flying capabilities. For example, high aspect ratio combined with low wing loading is used for slow flight such as gliding or soaring. See more The ratio of the length of wings to their width is called aspect ratio. A high aspect ratio indicates long, narrow wings. A low aspect ratio indicates short, wide wings. See more Generally, high aspect ratio wings give slightly more lift and enable sustained, endurance flight, while low aspect ratio wings are best for swift manoeuvrability. Stability: Long narrow wings give a plane or bird more stability. … See more Less fuel consumption: Having less induced drag means there is less fuel consumption for planes and birds (fat consumption) so they can keep their speed for a longer … See more Less induced drag Long, narrow wings also have less induced drag than shorter wider wings.
