Flight Deck Display System Integrating ATC Clearances and Safety Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air traffic control systems rely heavily on voice communications, which become saturated during peak periods and limit communication beyond line-of-sight, and the existing data communication systems for textual messages are cumbersome, time-consuming, and distracting for pilots, requiring separate updates to flight plans and lacking safety alerts for environmental and avionic factors.
Innovation Solution
A flight deck communication and display system that processes current flight plans and air traffic control clearance messages, displaying both graphically and textually, with alerts for safety, compliance, and environmental concerns, allowing simultaneous display of current and modified flight plans and providing alerts for potential hazards and aircraft performance limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If voice communication channels are used for air traffic control, then real-time communication is achieved, but the channels become saturated during peak traffic periods
Solution Approach 1:
The patent combines voice communication and data communication systems into an integrated flight deck display system. ATC messages are received via data communication, processed, and displayed alongside voice communication capabilities, allowing both communication modes to operate simultaneously without interfering with each other, thereby increasing overall communication capacity
Solution Approach 2:
A message processing system acts as an intermediary between the data communication channel and the pilot. The system receives standardized ATC messages, converts them into pilot-friendly formats, and presents them on the flight deck display, reducing the communication burden on voice channels while maintaining real-time interaction
2Productivity
If standardized textual messages are used for controller-pilot communication, then communication load on voice channels is reduced, but message creation and processing becomes cumbersome and time-consuming
Solution Approach 1:
The system automatically processes incoming ATC clearance messages by comparing them against the current flight plan stored in the flight management system. The processor autonomously determines whether the clearance can be complied with and generates appropriate pilot responses without requiring manual message composition, significantly reducing pilot workload and processing time
Solution Approach 2:
The flight management system pre-stores the current flight plan data before ATC messages arrive. When a clearance message is received, the system immediately compares it against the pre-loaded flight plan, enabling rapid compliance assessment and response generation without requiring pilots to manually retrieve or analyze flight plan details
3Loss of information
If separate display systems are used for ATC messages, then message information is provided, but pilot attention is diverted from main flight deck displays
Solution Approach 1:
The patent integrates the ATC message display function directly into the existing flight deck display system. Clearance messages, compliance status, and system-generated responses are all presented on the same display screen used for flight information, eliminating the need for separate display systems and keeping all critical information in one location
Solution Approach 2:
The flight deck display system is designed to perform multiple functions simultaneously: displaying flight plan information, showing ATC clearance messages, indicating compliance status, and presenting system-generated responses. This multi-functional approach eliminates the need for dedicated separate displays while providing comprehensive information to the pilot
4Manufacturing precision
If pilots manually interpret and update flight plans based on ATC clearances, then flight plan accuracy is maintained, but misinterpretation errors and safety risks increase
Solution Approach 1:
The system provides automatic feedback by comparing incoming ATC clearance messages against the stored flight plan and notifying the pilot of any discrepancies or compliance issues. The processor analyzes whether the clearance can be complied with and alerts the pilot to potential problems, reducing reliance on manual interpretation and minimizing human error
Solution Approach 2:
The patent replaces the manual mechanical process of pilot interpretation and flight plan updating with an automated electronic processing system. The processor automatically compares clearances against the flight plan, determines compliance status, and generates appropriate responses, eliminating human interpretation errors while maintaining flight plan accuracy

AI summary
A flight deck communication and display system (100) for displaying a modified flight plan transmitted to an aircraft (224) is described including a processor (104) adapted to receive (i) data representative of a current aircraft flight plan (218, 228) and (ii) a textual message representative of the modified flight plan (218′, 228′) and operable, in response thereto, to supply a flight plan display command, and a modified flight plan display command, and comparing the textual clearance message with factors affecting aircraft safety to supply an alert message display command (204). A display (108) coupled to receive the flight plan display command, the modified flight plan display command, the alert message display command is operable, in response thereto, to substantially simultaneously display (308) (i) an image representative of the current aircraft flight plan, (ii) the textual clearance message, (iii) the modified flight plan, and (iv) an alert message indicating whether there are any safety concerns related to the textual air traffic modified flight plan.
