Embodiment Construction

[0022] System overview and functional architecture

[0023] The core function of HSVGS is that when encountering low-visibility weather conditions during flight, HSGVS can provide pilots with simulated images of the current aircraft's external terrain, obstacles and airports on the combined mirror of the HUD system, and provide pilots with current aircraft status information Display, provide pilots with flight guidance information and other auxiliary decision-making information, enhance the pilot's perception of the external environment, and achieve equivalent visual flight. The goal of the HSGVS system is to help aircraft complete CATII landings at airports that do not have CATII landing conditions.

[0024] According to the above overall functions of the HSGVS system are as follows:

[0025] a) Provide real-time simulation of three-dimensional terrain images within the 360-degree field of view area with the pilot's eye point as the viewpoint;

[0026] b) Provide display of...

Abstract

The invention belongs to the field of aviation electronic systems and particularly relates to an HUD based synthetic vision guiding display system. At present, an SVS (synthetic vision system) only can be displayed in a head-down display, and during high-speed taxiing, even the fastest scanning of a lower traditional instrument can lead to vision interruption with the outside world. An HGS (head-up guidance system) is not endowed with ability of displaying a three-dimensional terrain synthetic vision, and when inclement weather is encountered, it is difficult to provide better vision awareness for a pilot. With the adoption of the HUD based synthetic vision guiding display system provided by the invention, fused display of a synthetic image of the SVS and a flight guiding image is realized on an HUD system, and a civil aircraft cockpit display system capable of strengthening situation sensing ability especially combines a three-dimensional image display technology with a flight guiding information calculation display technology to simulate an outer aircraft environment and display flight guiding data in a cockpit head-up display.

Description

technical field [0001] The invention belongs to the field of avionics systems, and in particular relates to a HUD-based synthetic visual guidance display system, a civil aircraft cockpit display system capable of enhancing situational awareness, especially a combination of three-dimensional graphics display technology and flight guidance information calculation and display technology, Simulate the outside environment and display flight director data on the cockpit head-up display. Background technique [0002] Instrument reference flight and visual reference flight are two means for pilots to obtain flight status and control flight. In the past 30 years, the safety of aircraft itself has been continuously improved. Due to the low visibility caused by harsh environments, it is difficult for pilots to establish a stable visual reference. The misjudgment of the current comprehensive flight status, and the resulting flight safety accidents, have become the main cause of flight s...
