话说飞行员为什么要跳伞。。。 An-2的飞行手册说:”仪表飞行下发动机挂掉的话,飞行员应该像法航某副驾驶一样向后拉满驾驶杆并保持机翼水平,前缘襟翼将在大概64km/h的时候自动展开,空速降到40km/h的时候飞机将以降落伞的下降率下滑,直到booom“ (原文)A note from the pilot's handbook reads: "If the engine quits in instrument conditions or at night, the pilot should pull the control column full aft and keep the wings level. The leading-edge slats will snap out at about 64 km/h (40 mph), and when the airplane slows to a forward speed of about 40 km/h (25 mph), the airplane will sink at about a parachute descent rate until the aircraft hits the ground."
