Engineering Contradiction Analysis
1Extent of automation
If multiple independent avionics systems are used for flight conduct, then the functionality and automation level are improved, but the system complexity and crew workload increase
Solution Approach 1:
The patent merges multiple independent avionics systems (FMS, AFCS, AT, FCS) into a unified architecture where a central trajectory generation device integrates trajectory segments from different sources. This consolidation maintains the functional capabilities of each system while reducing overall system complexity and improving coordination between subsystems.
Solution Approach 2:
The trajectory generation device serves as a universal platform that handles multiple functions: it generates trajectory segments, selects optimal segments based on operating modes, and coordinates with various avionics systems. This multi-functional approach replaces the need for separate specialized systems, reducing complexity while maintaining automation capabilities.
2Extent of automation
If multiple independent avionics systems are used for flight conduct, then the automation capabilities are enhanced, but the crew workload increases
Solution Approach 1:
The central trajectory generation device acts as an intermediary between the crew and multiple avionics systems. It manages the complexity of coordinating FMS, AFCS, AT, and FCS, presenting a simplified interface to the crew while maintaining enhanced automation capabilities through systematic integration.
3Adaptability or versatility
If multiple independent avionics systems are used, then the functional capabilities are improved, but confusion and safety risks increase
Solution Approach 1:
The patent segments the trajectory into multiple trajectory segments, each generated by different avionics systems according to specific operating modes. This segmentation allows each system to contribute its specialized functionality while the central coordination ensures safe and coherent integration, reducing confusion and improving overall flight safety.

AI summary
This method makes it possible to generate a resulting setpoint trajectory of an aircraft, a guiding system controlling the trajectory of the aircraft relative to the resulting setpoint trajectory.The generating method is implemented by an electronic device and comprises selecting at least one mode from among several operating modes, acquiring a setpoint trajectory prepared by a flight management system, obtaining an alternative setpoint trajectory from an element from among a module for computing a trajectory and an external generating system, and generating the resulting setpoint trajectory, which includes one or several segments of the alternative setpoint trajectory for the period of time corresponding to the selection of another mode.
