Solution Overview

Problem

Current systems for monitoring and predicting incursions, excursions, and confusion events at airports are limited by excessive false alerts, incomplete coverage, and reliance on geometric constraints, failing to account for actual aircraft dynamics and considering only collisions, thus lacking in accuracy and timeliness.

Innovation Solution

A system that monitors a mobile platform's kinematic motion using position, velocity, acceleration, and surface geometry to predict potential undesired events, generating alerts to crew members, and considers the number of turns required for adjacent vehicles to reach the platform's surface, using on-board and remote databases and processors to analyze kinematic motions and physical constraints.

1Ease of manufacture

If geometric constraints and arbitrary rules are used to define runway protection areas, then the system is simple to implement, but the prediction accuracy of incursions is limited

Engineering Contradiction:
Improveease of implementationVSAvoidprediction accuracy
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The system transitions from using static geometric parameters (3-D box dimensions) to dynamic kinematic parameters (velocity, acceleration, trajectory) to predict aircraft motion. This allows the system to adapt to actual aircraft dynamics rather than relying on arbitrary geometric constraints, thereby improving prediction accuracy while maintaining implementation feasibility through standardized sensor data collection.

2Device complexity

If only time-to-event or speed estimates are used for aircraft movement analysis, then the calculation is simple, but the prediction of incursions lacks accuracy

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The system incorporates dynamic parameters including velocity and acceleration measurements from aircraft sensors, rather than relying solely on static speed estimates. By continuously updating the aircraft's kinematic state and predicting future positions based on current motion dynamics, the system achieves more accurate incursion predictions while managing computational complexity through efficient trajectory calculation algorithms.

Inventive Principle:
Principle #15Dynamics

3Reliability

If scenario-based monitoring with complete scenario coverage is used, then all possible incursions can be detected, but the system generates excessive false alerts

Engineering Contradiction:
Improveincursion detection completenessVSAvoidfalse alerts
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The system performs preliminary risk assessment by calculating predicted aircraft trajectories and identifying potential incursion scenarios before they occur. By pre-computing risk levels based on kinematic parameters and comparing them against defined thresholds, the system can distinguish between high-risk situations requiring alerts and low-risk situations that would generate false positives, thereby reducing false alerts while maintaining comprehensive detection coverage.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If arbitrary boundaries and performance attributes are defined for runway protection, then the system is easy to configure, but it cannot cover all possible incursion scenarios

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system uses universal kinematic parameters (position, velocity, acceleration) that apply to all aircraft types and all incursion scenarios, rather than requiring separate configuration for each scenario type. The trajectory prediction algorithm universally handles different aircraft dynamics and runway configurations, enabling the system to adapt to any incursion scenario while maintaining simple configuration through standardized parameter definitions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A method for predicting the occurrence of an undesired operating event for a mobile platform operating within a designated area. The method may involve obtaining a plurality of parameters including a position of the mobile platform within the designated area for determining a kinematic motion of the mobile platform while the mobile platform is operating within the designated area. Information may also be obtained that relates to surface geometry of the designated area. The information related to surface geometry may be used to determine physical constraints within the designated area that limit operation of the mobile platform within the designated area. The plurality of parameters may be used to determine a kinematic motion of the mobile platform within the designated area. The kinematic motion of the mobile platform and the physical constraints may be used to predict if motion of the mobile platform will cause it to incur an undesired operating event.
