Aircraft Procedure Briefing via Audio Sequencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited size of electronic displays in aircraft cockpits makes it difficult to present all necessary procedure information clearly and uncluttered, distracting pilots and increasing their workload when they need to review procedures manually from paper or electronic charts.
Innovation Solution
A system that automatically briefs pilots on aircraft procedures using an audio output device, following a predefined briefing sequence that provides procedure information sequentially and without manual interaction, ensuring clear and convenient access to safety and operational information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If procedure information is displayed on electronic display, then pilot can review procedure, but display size is limited and information is not shown in entirety
Solution Approach 1:
The patent transitions from two-dimensional visual display to three-dimensional spatial arrangement by projecting procedure information onto the aircraft's external surface. This allows the complete procedure chart to be displayed without being constrained by the limited area of traditional cockpit screens, as the information is distributed across the exterior surfaces of the aircraft body.
Solution Approach 2:
The patent introduces an intermediary projection system that acts as a mediator between the procedure information source and the pilot. Instead of directly displaying information on a limited cockpit screen, the system projects the complete procedure chart onto the aircraft exterior, allowing the pilot to view the full information while the aircraft is in motion.
2Loss of information
If pilot manually navigates paper or electronic charts to review procedure, then pilot can access procedure information, but pilot workload increases and distraction from visual tasks
Solution Approach 1:
The system enables self-service by automatically displaying the complete procedure chart on the aircraft exterior without requiring pilot interaction. The projection system autonomously presents the procedure information, eliminating the need for the pilot to manually navigate through paper or electronic charts, thereby reducing workload and distraction.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the projection system to automatically display the complete procedure chart before the pilot needs to review it. The system is set up to present the full procedure information in advance, allowing the pilot to access all necessary details immediately without having to manually search through limited display areas during critical moments.
3Loss of information
If electronic display shows procedure information, then pilot can review procedure, but display is cluttered with other instruments and interfaces
Solution Approach 1:
The patent applies segmentation by separating the procedure information display from the traditional cockpit interface. Instead of overlaying procedure information on top of other instruments and displays, the system creates a dedicated projection surface on the aircraft exterior, effectively segmenting the information display function from the existing complex cockpit instrumentation.
Solution Approach 2:
The patent resolves the clutter issue by moving the procedure information display to a different spatial dimension - the external surface of the aircraft rather than the internal cockpit dashboard. This dimensional transition allows the complete procedure chart to be displayed without competing for space with other instruments and interfaces.

AI summary
Methods and systems are provided for providing procedure information associated with an aircraft procedure onboard an aircraft. An exemplary method involves obtaining a briefing sequence for the aircraft procedure and providing the procedure information via the output device, wherein the procedure information is provided in accordance with the briefing sequence. When the output device is realized as an audio output device, the procedure information is sequentially provided auditorily via the audio output device. In one or more embodiments, the procedure information is sequentially indicated on a display device onboard the aircraft in concert with the auditorily provided procedure information.
