Helipad Misalignment Detection via Volumetric Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Helicopter pilots face challenges in accurately determining the misalignment between a helipad and its associated structure due to discrepancies in data from navigation and obstacle databases, leading to potential surprises during takeoff and landing.
Innovation Solution
A system that generates volumetric models from structure and helipad data stored in separate databases, calculates a correlation coefficient to assess overlap, and generates alerts for misalignment, allowing for pre-flight or real-time detection and compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If helicopter pilots rely on synthetic vision systems and database information for navigation, then situational awareness is improved, but accuracy of helipad and structure location data deteriorates due to discrepancies between navigation and obstacle databases
Solution Approach 1:
The patent introduces an intermediary system that acts as a mediator between the navigation database and obstacle database. This system detects misalignment between helipad locations from the navigation database and structure locations from the obstacle database, then provides correction information to reconcile the discrepancies. The intermediary detection system bridges the gap between the two databases, allowing pilots to maintain situational awareness while compensating for location data inaccuracies.
2Measurement precision
If pilots use visual cues to compensate for misalignment, then location accuracy is improved, but operational complexity increases due to additional pilot workload
Solution Approach 1:
The system performs preliminary detection of misalignment between helipad and structure locations before the helicopter arrives at the destination. By identifying and communicating the misalignment information in advance, the system allows pilots to mentally prepare and adjust their approach without requiring complex real-time visual compensation maneuvers. This preliminary action reduces the cognitive load and operational complexity during critical landing phases.
3Adaptability or versatility
If separate databases are used for navigation and obstacle data, then data versatility is improved, but system reliability deteriorates due to potential data discrepancies
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors and detects misalignment between the navigation database (helipad locations) and obstacle database (structure locations). When discrepancies are detected, the system generates feedback information about the misalignment, which can be used to alert pilots or potentially trigger database synchronization protocols. This feedback loop maintains data consistency awareness while preserving the versatility benefits of separate specialized databases.
Data Source
AI summary
A system is provided for detecting misalignment between a helipad and a structure associated with the helipad. The system comprises a first database that includes first structure data, which data can comprise a location of the first structure. The system can further comprise a second database that can include second structure data, where the second structure data can comprise a location of the second structure. The second structure can comprise a helipad situated atop the first structure. The system can further comprise a processor coupled to receive the first structure data from the first database and the second structure data from the second database and can be configured, upon receipt of the first data structure and the second data structure: determine a correlation coefficient based upon a degree of overlap of the first volumetric model and the second volumetric model, and selectively generate an alert based upon the correlation coefficient.
