Take-Off Climb Rate Control With Automated Remedial Actions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft systems lack real-time monitoring and control capabilities to ensure a sufficient climb rate during take-off, leading to potential obstacles avoidance issues and increased pilot workload due to manual confirmation methods.
Innovation Solution
An aircraft system comprising a controller that receives signals during take-off, determines if the climb rate meets a criterion, and initiates remedial actions such as adjusting thrust, flight control surfaces, or retracting landing gear to enhance climb performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual confirmation methods are used to check climb rate, then the system is simple, but the accuracy and timeliness of climb rate monitoring is insufficient
Solution Approach 1:
The controller continuously receives signals from sensors during take-off, automatically determines whether the climb rate meets the criterion, and initiates remedial actions if needed. This closed-loop feedback system replaces manual checking with automated real-time monitoring, significantly improving measurement precision and timeliness without requiring complex additional hardware.
2Reliability
If automated controller system is implemented, then climb rate monitoring accuracy improves, but device complexity increases
Solution Approach 1:
The controller autonomously performs the entire climb rate monitoring and response process: receiving sensor signals, determining criterion compliance, and initiating remedial actions without pilot intervention. This self-service capability enhances reliability by eliminating human reaction time delays and errors, while the complexity is managed through integrated control logic that leverages existing aircraft systems.
3Speed
If remedial actions are automatically initiated, then response time to climb rate deviations improves, but operational complexity increases
Solution Approach 1:
The controller is pre-programmed with the climb rate criterion and a library of remedial actions. When a deviation is detected, the appropriate remedial action is automatically selected and initiated immediately without requiring pilot analysis or decision-making. This preliminary preparation of response protocols maximizes response speed while maintaining operational simplicity through automated execution of pre-determined procedures.

AI summary
An aircraft system (10) for an aircraft (1) including a controller (100) configured to receive at least one signal during a take-off procedure of the aircraft. The signal includes information representative of at least one parameter of the aircraft. The controller is configured to determine whether a current or future aircraft climb rate associated with the take-off procedure meets a criterion, on the basis of the at least one signal. The controller is configured to determine at least one remedial action to be taken, such as performance of at least a portion of a procedure to retract a landing gear of the aircraft, when the controller determines that the aircraft climb rate does not meet the criterion.
