Obstacle Advisory Grid Display for Helicopter Landing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for aiding pilots during helicopter landing, takeoff, and near-ground maneuvering lack an effective and simplified display of obstacle information, which can lead to increased pilot workload and risk of collisions.
Innovation Solution
An obstacle advisory system that utilizes a processor and sensors to generate and display obstacle data in a grid format on a display, indicating distances and directions to obstacles around the vehicle, allowing operators to quickly identify potential hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If obstacle information is displayed using traditional circular displays with rings and sections, then obstacle direction and distance can be indicated, but the display becomes complex and requires multiple colors to distinguish warnings from alerts
Solution Approach 1:
The display is segmented into multiple blocks radiating from the center, with each block representing a specific direction and distance range. This segmentation allows obstacle information to be clearly indicated without requiring complex circular displays with multiple rings and sections, thereby reducing display complexity while maintaining information clarity.
Solution Approach 2:
Different blocks in the display are assigned different visual characteristics (such as color or intensity) based on the specific obstacle conditions in each direction. This local differentiation allows the system to convey multiple types of information (warnings, alerts, distance) using a simpler block-based structure rather than requiring a complex multi-color circular display.
2Reliability
If detailed obstacle data is presented to pilots, then collision risk can be reduced, but pilot workload increases
Solution Approach 1:
The system extracts only the most critical obstacle information and presents it in a simplified block display format, rather than presenting all available sensor data. This extraction of essential information maintains collision avoidance capability while significantly reducing pilot workload by eliminating unnecessary details.
Solution Approach 2:
The display shows partial obstacle information - specifically, only the most relevant blocks with obstacles are highlighted, rather than displaying complete and exhaustive obstacle data. This partial presentation maintains safety by focusing on critical threats while reducing the overall information load on the pilot.

AI summary
An obstacle advisory system for a vehicle and a method for operating the same are provided. The system, for example, may include, but is not limited to a display, and a processor communicatively coupled to the display, the processor configured to receive sensor data from at least one sensor configured to sense obstacles around a vehicle, generate obstacle display data based upon the sensor data, the obstacle display data comprising display data for each of a plurality of sectors and for each of a plurality of blocks within each of the plurality of sectors forming a grid surrounding the vehicle, and display the generated obstacle display data on the display.
