Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RTA speed regions are predefined with fixed parameters, then system reliability is improved, but adaptability deteriorates
Solution Approach 1:
The patent implements dynamic RTA speed region parameters that allow pilots to modify speed limits, adjust region boundaries, and reconfigure priority ordering during flight operations. The system transitions from static predefined parameters to dynamically adjustable parameters, enabling real-time adaptation to changing flight conditions while maintaining systematic control through the flight management system.
2Device complexity
If RTA speed parameters are fixed and predefined, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The system provides self-service capabilities by enabling pilots to directly interact with and modify RTA speed region parameters through the cockpit interface. Pilots can adjust speed limits, modify region boundaries, and reconfigure priority ordering without requiring ground controller assistance or complex manual procedures, thereby improving ease of operation while maintaining manageable system complexity through automated calculations and validations.
3Manufacturing precision
If RTA speed regions are predefined, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The patent enables dynamic modification of RTA speed region parameters including speed limits, region boundaries, and priority ordering. The system allows pilots to change these parameters in real-time based on actual flight conditions such as weather changes, traffic situations, or operational requirements, thereby achieving high adaptability while maintaining precision through systematic parameter management and automated recalculation of speed profiles.

AI summary
Systems and methods provide dynamically modifiable parameters in required time of arrival (RTA) speed regions of an assigned flight path of an aircraft. The system includes a vertical situation display (VSD) rendering thereon a vertical flight profile of the assigned flight path. A control module is coupled to the display system and configured to: demark the vertical flight profile with a plurality of RTA speed regions related to an initial speed profile; render an RTA speed band graphic having demarked sections vertically representing a speed minimum and speed maximum for an respective RTA speed region, the RTA speed band graphic representing a normalized speed range between zero and a maximum value for each respective RTA speed region. The control module accepts user modifications and updates the RTA speed band graphic and the current speed profile to reflect user input.
