Solution Overview
Problem
Pilots face high workload and risk of errors during taxi operations due to the need for mental determination of communication frequencies, which are dynamic and context-dependent, especially in complex airport environments where different frequencies are required for various phases of flight and control agencies.
Innovation Solution
A display system and method that determine a context-relevant communication frequency for an aircraft by using a controller circuit coupled with a source of the intended flight path, position determining system, and communication frequencies storage, presenting relevant frequencies on an avionic display and allowing pilots to select or activate them, thereby reducing manual workload and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pilots manually determine communication frequencies by comparing static published charts with dynamic aircraft position, then communication frequency information is available, but pilot workload increases and error risk increases
Solution Approach 1:
The system enables self-service by automatically determining the aircraft's context and suggesting appropriate communication frequencies without pilot intervention. The controller circuit continuously monitors aircraft position, orientation, and intended flight path, then autonomously identifies relevant frequencies from stored data, presenting them to the pilot for selection.
Solution Approach 2:
The patent replaces the manual mechanical process of comparing charts with position information with an automated electronic system. The controller circuit electronically processes position data from the position determining system, compares it with intended flight path information, and retrieves corresponding frequencies from stored communication frequencies, eliminating the need for manual chart consultation and mental determination.
2Adaptability or versatility
If pilots use static published charts for frequency reference, then frequency information is available, but the system cannot adapt to dynamic flight conditions
Solution Approach 1:
The system transforms the static frequency information from published charts into a dynamic adaptation system. The controller circuit continuously updates the aircraft's context by processing real-time position data and comparing it with the intended flight path, automatically identifying when the aircraft enters new contextual regions that require different communication frequencies.
Solution Approach 2:
The system implements feedback by continuously monitoring aircraft position and orientation from the position determining system, comparing this data with the intended flight path, and using this feedback loop to dynamically update the suggested communication frequencies based on the aircraft's current context and phase of operation.
3Adaptability or versatility
If multiple communication frequencies are stored for different control agencies, then comprehensive coverage is achieved, but frequency selection complexity increases
Solution Approach 1:
The controller circuit acts as an intermediary between the stored communication frequencies and the pilot. Instead of presenting all available frequencies from multiple control agencies, the system filters and prioritizes frequencies based on the determined aircraft context, phase of operation, and proximity to runways, presenting only the most relevant options to the pilot.
Solution Approach 2:
The system applies local quality by providing different frequency suggestions based on the specific contextual situation. Rather than a uniform approach for all flight phases, the controller circuit tailors the frequency recommendations to the local conditions - such as taxiing, takeoff, approach, or landing - and to the specific aircraft position relative to runways and control agency boundaries.

AI summary
Systems and methods for suggesting, on an avionic display in an aircraft, a communication frequency that is relevant to a context of the aircraft. The method includes determining a location and orientation of the aircraft and referencing an intended flight path to determine, based thereon, the context of the aircraft. The method uses the context to reference an on-board source of a plurality of stored navigation communication frequencies. The method identifies one or more relevant navigation communication frequencies for the context and presents the relevant navigation communication frequencies in a predefined area on an avionic display.
