[0002] At present, the importance of aircraft airborne equipment is considered from three dimensions: safety, mission, and economy. Through the judgment of "yes and no" on the functional items in each dimension, the three importances of equipment are obtained. Among them, the most important is the importance of equipment. This qualitative analysis method may cause the importance of airborne equipment to be inaccurate, and cannot guide the development of equipment in a targeted manner.

Embodiment Construction
[0017] The present invention will be described in detail below in conjunction with specific embodiments. Take computer as an example,
[0018] 1) The computer function list is as follows: the computer should be able to realize information interaction with the avionics system, should be able to realize control law calculation, should be able to suppress non-command oscillation, should be able to suppress sudden deviation, should be able to realize servo control, and should be able to Realize redundancy management. Note that this is only a part of the functions, the more comprehensive the functions are listed, the more accurate the importance level will be determined;
[0019] 2) Find the functional hazard level according to the functional hazard analysis FHA report;
[0020] 3) Through step 2), it is obtained that the computer should be able to realize the information interaction with the avionics system as a type III function, it should be able to realize the control law cal...

The invention discloses an onboard equipment importance level determination method. The onboard equipment importance level determination method is characterized in that a function realization dimensionality is included besides three dimensionalities of safety, tasks and economy, and the determination method specifically comprises the first step of listing a function list which the onboard equipment is supposed to achieve; the second step of seeking a function hazard analysis FHA report according to the function list; the third step of listing an FHA level of each function; the fourth step of listing a realization form of each function, wherein the realization forms comprises hardware or software; the fifth step of listing importance levels of the hardware and software of the equipment according to an importance level analysis principle, wherein the importance level analysis principle specifically comprises the step of adopting an importance level with the highest value as the importance level in the function realization dimensionality of the equipment, importance level analysis results of the three dimensionalities of safety, tasks and economy are combined, and the result with the highest value is adopted to be regarded as the importance level of the onboard equipment. Compared with a traditional method, the detection of one dimensionality is added, thus the onboard equipment importance level determination method is more precise and the determination of the importance level of the equipment is further more accurate.
Description
technical field [0001] The invention belongs to the technical field of aircraft airborne equipment, and relates to a method for determining the importance of airborne equipment. Background technique [0002] At present, the importance of aircraft airborne equipment is considered from three dimensions: safety, mission, and economy. Through the judgment of "yes and no" on the functional items in each dimension, the three importances of equipment are obtained. Among them, the most important degree is regarded as the importance degree of equipment. This qualitative analysis method may cause the importance degree of airborne equipment to be inaccurate, and cannot guide the development of equipment in a targeted manner. Contents of the invention [0003] The purpose of the invention is: the task of the present invention is to develop a method for analyzing the importance of airborne equipment. Starting from the assigned function, through the hazard analysis of the function, com...
