Aircraft Go-Around Alert Control for Unsafe Landing Approaches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots often face challenges in determining when to perform a go-around or aborted landing due to factors like pilot judgment, fear of admitting poor performance, and potential disruption to Air Traffic Control, leading to inexperienced pilots continuing with landings even when a go-around is necessary.
Innovation Solution
A go-around system that includes a controller, alert system, and auto throttle system, which receives flight path, airspeed, and runway information to determine if a go-around is required and automatically initiates the maneuver, providing visual, aural, or detailed alerts to the pilot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pilots rely on their own judgment to determine when to perform a go-around, then they maintain autonomy and control over the landing decision, but they may continue with unsafe landings due to psychological factors such as fear of admitting poor performance or concern about disrupting air traffic control
Solution Approach 1:
The patent introduces an autonomous alert system that acts as an intermediary between the aircraft's flight parameters and the pilot's decision-making process. The system objectively monitors flight path, airspeed, and runway information, then provides go-around advisories that mediate the pilot's judgment, eliminating psychological biases while maintaining pilot autonomy in the final decision.
Solution Approach 2:
The system implements continuous feedback by monitoring multiple flight parameters (flight path, airspeed, runway information) and providing real-time go-around advisories to the pilot. This feedback loop enables the pilot to make informed decisions based on objective system recommendations rather than subjective judgment alone, improving landing safety without increasing operational burden.
2Reliability
If pilots are required to carefully monitor multiple factors including approach speed, runway obstructions, altitude, and descent rate, then landing safety may be improved, but pilot workload and complexity of operation increase
Solution Approach 1:
The patent merges multiple monitoring functions into a single autonomous alert system that simultaneously tracks flight path, airspeed, runway obstructions, altitude, and descent rate. By combining these separate monitoring tasks into one integrated system, the patent improves landing safety through comprehensive parameter monitoring while reducing the perceived complexity for the pilot, who receives consolidated go-around advisories rather than managing multiple separate monitoring functions.
3Reliability
If an autonomous alert system is implemented to determine when to perform a go-around, then landing safety is improved through unbiased advisories, but the system complexity and initial operational burden increase
Solution Approach 1:
The autonomous alert system performs self-service by automatically monitoring all necessary flight parameters, calculating go-around criteria, and generating advisories without requiring manual input or complex configuration by the pilot. The system independently evaluates flight path, airspeed, and runway information against predetermined criteria, providing unbiased go-around recommendations that improve landing safety while minimizing the operational burden on the pilot.
4Speed
If the system automatically initiates go-around sequence, then response time and safety are improved, but the extent of automation increases which may reduce pilot situational awareness
Solution Approach 1:
The system prepares for automatic go-around initiation by pre-configuring the auto throttle and flight guidance systems with go-around parameters before a go-around is needed. When a go-around advisory is issued, the preliminary setup enables rapid automatic execution of the go-around sequence, improving response time while maintaining pilot awareness through prior notification and the ability to override the automatic initiation if circumstances change.

AI summary
The present disclosure relates to a go-around system for an aircraft. The go-around system includes a controller, an alert system, an auto flight system, and an auto throttle system. The controller is configured to receive flight path information, airspeed information, and runway information from one or more avionic systems, determine, based on the flight path information, airspeed information, and runway information, a go-around advisory, and output an alert signal regarding the go-around advisory. The go-around advisory is a directive to perform a go-around. The alert system is configured to provide at least one of a visual alert, an aural alert, and a detailed information alert to a user in response to receiving the alert signal from the controller. The auto throttle system is configured to automatically adjust a speed of the aircraft for a go-around based on the go-around advisory.
