Integrated Aviation Instrument for Engine Failure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In twin-engine aircraft, engine failure leads to difficult control due to unbalanced thrust, requiring pilots to interpret multiple instrument indications simultaneously, which distracts from flying and increases the risk of Vmc rollover.
Innovation Solution
A single aviation instrument with processing circuitry that displays necessary corrective actions on a familiar format, including performance indication graphics for rudder deflection, bank angle, and angle of attack, to help pilots counteract adverse yaw and maintain control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple separate instrument indications are used to provide comprehensive flight information, then the information completeness is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple separate instrument indications (airspeed, altitude, attitude, engine parameters, navigation) into a single integrated display unit. This consolidation presents all critical flight information on one screen, eliminating the need for pilots to scan multiple separate instruments, thereby reducing device complexity while maintaining information completeness.
Solution Approach 2:
The display unit serves multiple functions simultaneously: it acts as an airspeed indicator, altimeter, attitude indicator, engine monitor, and navigation display all in one device. This multi-functionality approach allows a single instrument to replace traditional multiple separate instruments, resolving the contradiction between information completeness and device complexity.
2Loss of information
If multiple separate instrument indications are used to provide comprehensive flight information, then the information completeness is improved, but the ease of operation deteriorates
Solution Approach 1:
By merging all critical flight parameters into a single integrated display, the system eliminates the cognitive burden of cross-referencing multiple separate instruments. The unified presentation allows pilots to obtain complete flight information at a glance, significantly improving ease of operation during normal flight and especially during emergency situations.
Solution Approach 2:
The display utilizes a two-dimensional graphical interface that presents three-dimensional flight state information in an intuitive visual format. This dimensional transformation allows complex multi-parameter information to be displayed in a spatially organized manner that is easier for pilots to process quickly, reducing workload while maintaining information completeness.
3Measurement precision
If pilots must interpret multiple instrument indications simultaneously during engine failure, then the measurement precision of flight parameters is maintained, but the loss of time increases
Solution Approach 1:
The integrated display consolidates all critical flight parameters and their interrelationships in a single visual field, allowing pilots to assess the complete flight state instantly without sequentially checking multiple instruments. This maintains measurement precision of individual parameters while dramatically reducing the time required to interpret the overall flight situation during emergencies.
Solution Approach 2:
The system pre-organizes and pre-presents all relevant flight information in an intuitive layout before emergencies occur. During engine failure, the display already shows all necessary parameters in their correct contextual relationships, eliminating the need for pilots to mentally process and correlate data from multiple separate sources, thus reducing reaction time while maintaining accuracy.
4Reliability
If pilots must perform multiple corrective actions simultaneously during engine failure, then the reliability of emergency response is improved, but the ease of operation deteriorates
Solution Approach 1:
The integrated display merges all flight control parameters and engine status information into a unified view, allowing pilots to monitor the effects of multiple simultaneous corrective actions without losing situational awareness. This maintains reliable emergency response by providing complete information while improving ease of operation through simplified information presentation.
Solution Approach 2:
The display provides real-time feedback on the effects of pilot corrective actions across all flight parameters simultaneously. As pilots adjust controls during engine failure, the integrated display immediately shows the combined effects on airspeed, altitude, attitude, and engine parameters, maintaining situational awareness while enabling reliable multi-task emergency response.
Data Source
AI summary
A maximum performance instrument for an aircraft is configured to aid a pilot in taking corrective action, after loss of functionality of one of the aircraft engines, in order to maintain as much control of the aircraft as possible. The information is provided to the pilot on a single instrument display in a format that is familiar to most pilots so that the information is immediately usable by the pilot without a high degree of proficiency or training with the instrument.
