Embodiment Construction

[0014] by figure 1 , figure 2 It can be seen that the two flight instruments are directly connected to the normal direct current, and when the direct current changes instantaneously, the black screen will occur.

[0015] and image 3 , Figure 4 Provides an optimized electronic flight instrument power supply system, and this optimized solution has been verified in a certain type of aircraft, effectively solving the faults and defects caused by the original power supply system. This electronic flight instrument power supply system includes a left electronic attitude indicator (hereinafter referred to as EADI), a left electronic horizontal position indicator (hereinafter referred to as EHSI), and a left display processor ( Hereinafter referred to as DPU), the left emergency bus bar, and the right EADI, right EHSI, right DPU, power conversion relay, right emergency bus bar, and mounting bracket installed on the aircraft's right DC circuit breaker board. Such as image 3 The power ...

Abstract

The invention provides a power supply system of electronic flight instruments. The power supply system can solve the problem of black screens and can not increase operation burden of a pilot. The system comprises an electronic gesture guide indicator arranged on a plane direct current breaker plate, an electronic horizontal position indicator, a display processor, an emergency bus bar and a power conversion relay. The emergency bus bar is used for providing stable power supply for an electronic flight instrument system. Power supply needed by the electronic flight instrument system is displayed and supplied automatically. Obsession, brought by the operation of a power switch of a display, on the pilot is removed.

Description

Technical field [0001] The invention belongs to the technical field of aircraft integrated avionics, in particular to an electronic flight instrument power supply system. Background technique [0002] Electronic Flight Instrument System (EFIS) provides the display of flight data and navigation data for left and right pilots. It receives information from the receiving aircraft's heading and attitude system, air data system, autopilot, omnidirectional beacon / instrument landing / The output signals of the pointing beacon system, rangefinder, automatic direction finder, navigation system, radio altimeter and weather radar system provide corresponding display information for left and right driving. It is also used to display weather radar, navigation station / waypoint, autopilot working mode, comparison warning, airspeed trend, self-check meter and diagnostic information. At the same time, the autopilot is provided with relevant information such as preselected course and main course. ...
