Cockpit Display Overlaying Beacon Location on Synthetic Terrain View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During search and rescue operations, especially in adverse weather conditions and remote locations, pilots face challenges in safely navigating aircraft while manually locating beacon signals, as existing synthetic vision systems do not provide adequate situational awareness for identifying and reaching the source of the beacon.
Innovation Solution
A cockpit display system that renders a synthetic perspective view of terrain along with a graphical representation of the beacon location, using location data from beacon signals, to enhance situational awareness and facilitate navigation to the target object, incorporating navigational parameters and rescue criteria for intuitive display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pilots manually navigate to beacon locations using existing synthetic vision systems, then they can locate target objects, but their workload increases and situational awareness is reduced in adverse weather conditions
Solution Approach 1:
The system introduces an automated beacon detection and tracking subsystem that acts as an intermediary between the raw beacon signals and the pilot. This subsystem automatically processes beacon signals, determines their locations, and presents the information to the pilot in an intuitive format, thereby reducing pilot workload while maintaining accurate beacon location identification.
Solution Approach 2:
The system replaces the manual mechanical process of visually scanning and identifying beacon locations with an automated electronic detection and display system. The automated system uses signal processing and graphical display technologies to identify and present beacon locations, eliminating the need for manual visual search and reducing pilot cognitive load.
2Productivity
If pilots manually locate beacon signals in remote locations with rough weather, then they can perform search and rescue operations, but their ability to safely operate the aircraft is compromised
Solution Approach 1:
The system divides the complex task of search and rescue into separate functional modules: one module dedicated to aircraft safety and navigation, and another module dedicated to beacon detection and target location. This segmentation allows the pilot to focus on safe aircraft operation while the system handles beacon location tasks, thereby maintaining both safety and operational effectiveness.
Solution Approach 2:
The system provides continuous feedback to the pilot about beacon locations, aircraft position, and navigation status through the graphical display. This feedback loop enables the pilot to make informed decisions about aircraft operation and beacon pursuit, maintaining situational awareness and aircraft safety while conducting search and rescue operations in challenging conditions.
3Reliability
If existing synthetic vision systems provide three-dimensional terrain views, then pilots can navigate safely, but they still lack adequate situational awareness for locating beacon sources
Solution Approach 1:
The system merges the three-dimensional terrain visualization capability with beacon location information display in a unified graphical interface. The beacon locations are overlaid on the three-dimensional terrain view, allowing the pilot to simultaneously perceive both terrain features for safe navigation and beacon positions for target acquisition, thereby eliminating the information gap without compromising terrain awareness.
Data Source
AI summary
Systems and methods are provided for displaying information on a display device associated with an aircraft. A method comprises rendering a synthetic perspective view of terrain on the display device, wherein the synthetic perspective view of terrain is based on a set of terrain data corresponding to a region proximate the aircraft. The method further comprises obtaining location data for a first object, wherein the location data is based at least in part on a beacon signal associated with the first object, and rendering a graphical representation of the first object on the display device. The graphical representation of the first object overlies the synthetic perspective view of terrain and is positioned in accordance with the location data.
