Multi-member airplane avionic system

Abstract

The invention discloses a multi-member airplane avionic system which comprises a mode control panel MCP, a primary flight display PFD, a multifunctional display MFD, an automatic pilot / flight directorAP / FD, a flight management system FMS, a tune control panel TCP, an audio control panel ACP, data interface units DIU, an air data system ADS, an inertial navigation / global positioning system INS / GPS, a very high frequency broadcasting station VHF, an ILS / VOR and a multitask audio management unit AMU. The first data interface unit and the second data interface unit are used for performing dual-redundancy transmission and treatment on airborne equipment data; furthermore, high-reliability flight management can be achieved through the unified flight management system, the problems that a traditional multi-member airplane flight management system has larger volume and weight and higher cost are overcome, and the multi-member airplane avionic system can be applied to upgrading and transforming comprehensive avionic systems of varieties of traditional multi-member airplanes.

Description

technical field [0001] The invention relates to the technical field of avionics equipment, in particular to a multi-member aircraft avionics system. Background technique [0002] Modern aircraft usually use a unified processor to uniformly process the information of various avionics equipment on the aircraft, combine devices with the same or similar functions into one component, comprehensively display relevant parameters on the display, and display them in various avionics The relevant information is transmitted through the on-board data bus, so that the performance of all avionics on the entire aircraft can reach a higher level. Such a system is called an integrated avionics system. [0003] However, due to the over-design of the flight management system and data processing redundancy in traditional multi-crew aircraft, and the over-dispersion of the avionics system, the system has problems such as large volume, weight and high cost. Moreover, the original system cannot b...

Problems solved by technology

[0003] However, due to the over-design of the flight management system and data processing redundancy in traditional multi-member aircraft, and the over-dispersion of the avionics system, the system has problems such as large volume, weight and high cost.

Moreover, the original system cannot be connected with various existing airborne equipment, so it cannot take into account the centralized data processing and system redundancy backup design well, resulting in low reliability of the system as a whole, and it is inconvenient to carry out subsequent system expansion or upgrade transform
