Cockpit Display Frequency Identifier Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft crew members face difficulties in identifying the communications centre when taking over radio communications due to the lack of automatic recording of the centre's identifier alongside the frequency, leading to manual and error-prone processes, especially when transitioning between air sectors.
Innovation Solution
A method and system for automatically determining and displaying the identifier of the communications centre corresponding to the entered radio communications frequency on the cockpit display, using geographical and sector-based criteria to compare frequencies and locate the relevant centre.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pilot manually writes the identifier of the communications centre to the display unit, then the identifier is recorded for future reference, but the workload increases and the process becomes error-prone
Solution Approach 1:
The system automatically performs the task of recording the communications centre identifier by comparing the entered frequency with stored frequency-identifier pairs, eliminating the need for manual pilot intervention and reducing both workload and error potential
Solution Approach 2:
The manual mechanical process of writing the identifier by hand is replaced by an automated electronic system that uses computer algorithms to match frequencies and retrieve corresponding identifiers from a database
2Loss of information
If only the frequency is written to the display unit without the identifier, then the display remains simple, but another crew member cannot identify which communications centre is being contacted
Solution Approach 1:
The system introduces an automated intermediary process that links the frequency entry with the corresponding identifier from a database, allowing the display to show both pieces of information without requiring manual input or complex display modifications
Solution Approach 2:
The display unit is enhanced to serve multiple functions: it displays both the frequency and the automatically retrieved identifier, making it a comprehensive communication reference tool without requiring separate systems
3Productivity
If the pilot has to perform multiple tasks during sector transitions, then all necessary communication procedures can be completed, but the additional manual recording creates time consumption and potential errors
Solution Approach 1:
The system performs the identifier retrieval action automatically and immediately when the frequency is entered, before the pilot needs to use the information, eliminating the time required for manual recording during critical handover periods

AI summary
A method for the determining, on board an aircraft, of an identifier of a communications center with which an aircraft crew wishes to enter into contact, includes the following operations: a) the writing, by the crew, of a radio-communications frequency to a display unit of the cockpit of the aircraft, b) the determining of surroundings of the aircraft, c) the determining of the communications centers situated in these surroundings, d) the comparing of the frequencies of these communications centers with the frequency displayed on the display unit of the cockpit, and f) when the frequency of a communications center is identical to the displayed frequency, the display on the aircraft display unit of the identifier of said communications center having a frequency identical to the displayed frequency.
