现在攻击机武器的精确瞄准,是用中央计算机与各种传感器相联接的方法来实现的。最近发表的马可尼──埃利奥特航空电子系统公司的664型平视显示武器瞄准系统(HUDWAS)将安装在轻型战斗机上。虽然它没有A—7、猎兔狗或美洲豹虎那样的先进航空电子设备,但是664型平视显示武器瞄准系统,可使轻型战斗机具有与上述飞机一样的瞄准精度。 664型瞄准系统,不包括传感器插头和安装座,重量为47磅。它的成本低于较复杂系统的平视显示装置,另外它允许轻型战斗机的飞行员以平飞或任意的俯冲角接近目标。664型的简单飞行导向仪
Accurate targeting of attack aircraft weapons is now achieved using a central computer coupled with a variety of sensors. The recently announced Marconi-Eliot Avionics Systems’ 664 HUDWAS will be installed on light fighter jets. Although it lacks advanced avionics such as the A-7, the Hound or the Jaguar Tiger, the 664 HUD aiming system gives the light fighter the same aiming accuracy as the aircraft described above. 664 aiming system, does not include the sensor plug and mount, weighs 47 pounds. It costs less than the head-up display of a more complex system, and it allows pilots of light fighter jets to approach the target at level or any pitch angle. Model 664 simple flight director
