随着现代航空电子产品的不断发展,从飞行指引仪(F/D),自动驾驶仪(A/P)和自动油门系统(A/T)发展到现在的数字式飞控系统(DFCS),已经使飞行的可操纵性、自动化程度和安全可靠性提高到过去无法比拟的水平。平视导引系统(HGS)的出现,从另一个角度上消除了飞行对自动系统的过份依赖并进一步保证了进近、着陆及起飞的精确性,也是FAA唯一批准允许飞行员在能见度244米条件下飞行的系统。
With the continuous development of modern avionics, the digital flight control system (DFCS) has been developed from flight director (F / D), autopilot (A / P) and automatic throttle system (A / T) The maneuverability, automation and safety of the flight have been increased to levels unmatched by the past. The emergence of HGS (Hidden Vision) system, on the other hand, eliminates the excessive dependence of the flight on the automatic system and further ensures the accuracy of approach, landing and take-off. It is also the only FAA approval to allow pilots to operate at visibility of 244 meters Under the flight system.
