Description

Aircraft Flight Control System The present invention relates to a flight control system for controlling the flight of an aircraft. The flight control system generates appropriate control signals for the aircraft based on information collected from various sensors mounted on the aircraft. Meanwhile, it is desirable for the aircraft to be equipped with safety diagnostic functions for preventing aircraft accidents and a flight data storage device for accident analysis in the event of an accident. While it is desirable to equip small aircraft or unmanned aerial vehicles with flight data storage devices as described above, the weight of the flight data storage device itself, the weight of various connecting components such as cable assemblies connecting the flight data storage device to sensors, and the power consumed by the flight data storage device place a significant burden on the aircraft's energy efficiency. The matters described above as background technology are intended only to enhance understanding of the background of the present invention and do not constitute prior art already known to those skilled in the art. FIG. 1 is a configuration diagram illustrating an embodiment of a flight control system for an aircraft according to the present invention. FIG. 2 is a flowchart illustrating the operation of the input/output module of FIG. 1, FIG. 3 is a flowchart illustrating the operation of the control module of FIG. 1, Figure 4 is a diagram illustrating the storage area of the DPRAM of the input/output module of Figure 1. In describing the embodiments disclosed in this specification, if it is determined that a detailed description of related prior art may obscure the essence of the embodiments disclosed in this specification, such detailed description is omitted. Furthermore, the attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings; it should be understood that they include all modifications, equivalents, and substitutions that fall within the spirit and technical scope of the present invention. Terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but said components are not limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. A singular expression includes a plural expression unless the context clearly indicates otherwise. In this specification, terms such as “comprising” or “having” are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.
