Engine-Out Flight Guidance Overlay for Takeoff Failure Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft engine out procedures rely on manual input and memory, leading to a high risk of safety-critical errors during high-pressure emergencies.
Innovation Solution
A system that automatically generates and displays an engine out flight plan on an aircraft display device, receiving an engine out procedure, detecting engine anomalies, and updating a guidance aid overlay to show a flight attitude based on the plan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input and memory-based procedures are used for engine out scenarios, then pilots have flexibility in handling emergencies, but the risk of safety-critical errors increases significantly
Solution Approach 1:
The system enables self-service by automatically generating the engine out flight plan and updating the flight director without requiring manual pilot input. The flight management system detects engine anomalies and autonomously computes the appropriate escape procedure, reducing reliance on pilot memory and manual operations during high-stress emergencies
Solution Approach 2:
The system performs preliminary action by pre-computing and storing engine out flight plans based on aircraft state and environmental conditions before emergencies occur. When an engine anomaly is detected, the pre-computed procedure is immediately activated and displayed, eliminating the need for pilots to manually calculate escape routes during the emergency
2Reliability
If automated systems are introduced to reduce manual input errors, then safety-critical error reduction is achieved, but system complexity increases
Solution Approach 1:
The flight management system performs multiple functions using existing infrastructure: it monitors engine parameters, detects anomalies, computes flight paths, updates the flight director, and manages display outputs. This multi-functionality approach avoids the need for separate dedicated systems for each function, thereby reducing overall system complexity while maintaining automation benefits
Solution Approach 2:
The system uses the existing flight management system and flight director as intermediaries to bridge between engine anomaly detection and escape procedure execution. Rather than creating direct complex connections between all components, the flight management system acts as an intermediary that processes information and coordinates updates across multiple subsystems

AI summary
A system for displaying an engine out flight plan via an aircraft display device includes a processor and computer-readable memory operably connected to the processor. The computer-readable memory is encoded with instructions that, when executed by the processor, cause the system to perform the following step: receive an engine out procedure, generate the engine out flight plan based upon the engine out procedure, display the engine out flight plan via the aircraft display device, receive an indication of an engine anomaly, and update a guidance aid overlay on the aircraft display device to display a flight attitude based upon the engine out flight plan in response to the indication of the engine anomaly via the aircraft display device.
