Aircraft Landing Runway Centerline Deviation Alert System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for aiding aircraft landing on a runway lack effective automation for detecting and alerting pilots of potential lateral exit risks, relying heavily on manual monitoring during the approach phase.
Innovation Solution
A method and system utilizing a processing unit within the aircraft to acquire and compare information about the aircraft's position and situation with reference to the landing runway, determining deviations from a central longitudinal axis and triggering alerts if thresholds are exceeded, thereby automatically signaling potential lateral exit risks to the pilot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual monitoring is used during the approach phase, then the pilot can detect lateral exit risks, but the automation level is low and pilot workload is high
Solution Approach 1:
The system enables self-service by automatically acquiring aircraft position data from onboard sensors, computing deviation from the runway centerline, and generating alerts without requiring continuous manual monitoring by the pilot. The processing unit autonomously performs all detection and evaluation functions.
Solution Approach 2:
The patent replaces the manual mechanical monitoring process with an automated electronic system that uses sensors, a processing unit, and signaling devices to detect and alert about lateral exit risks, eliminating the need for continuous pilot attention to this specific task.
2Reliability
If automated detection system is implemented, then safety is improved through timely alerts, but device complexity increases
Solution Approach 1:
The system achieves multi-functionality by using the aircraft's existing onboard sensors and flight management systems for multiple purposes: navigation, position monitoring, and lateral exit risk detection. This leverages existing infrastructure rather than adding completely new specialized equipment.
Solution Approach 2:
The processing unit acts as an intermediary that receives data from existing aircraft systems, processes this information to determine lateral deviation, and generates alerts when thresholds are exceeded. This intermediary layer integrates seamlessly with existing aircraft architecture.

AI summary
A method for aiding the landing of an aircraft on a landing runway comprises the following steps implemented in an automatic manner by a processing unit: a) acquiring information relating to the landing runway; b) acquiring information relating to a current situation of the aircraft; c) determining, as a function of said information, at least one deviation between at least one parameter relating to a landing position of the aircraft on the landing runway and a reference relating to a central longitudinal axis of the landing runway; d) comparing this deviation with a predetermined threshold; and e) as a function of the result of the comparison carried out in step d), commanding, if appropriate, the signaling of an alert by means of a signaling system of the aircraft.
