41. Performance of the Ka-2 was found to be lower than expected, due to the relatively high wing loading . 42. The He 219 was particularly prone to this; its high wing loading at the edge of stalling speed left it unmanoeuvrable. 43. As a rule of thumb, a wing loading of 25 kg / m 2 is considered the limit for avian flight. 44. The surface area was almost 28 m?( 300 ft?), giving a wing loading of around 150 kg / m? 45. The actual stall speed of an aircraft also varies with flight conditions, particularly changes in gross weight and wing loading during maneuvers. 46. For all these a low W S is critical, whereas passerines and cliff dwelling birds can get airborne with higher wing loadings . 47. Due to its light weight and light wing loading ( 10 lb / sq ft ), the aircraft is sensitive to turbulence. 48. The most significant change was the fitting of a new, longer set of wings that gave the aircraft a lower wing loading . 49. Maneuverability and stability during low-level, high-speed flight were excellent due to the aircraft's high wing loading . 50. The combination of smaller wings and increased body mass-produce higher wing loading in these birds, resulting in faster flying speeds.
