Autopilot Intent Display for Reducing Pilot Automation Surprises
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots in general aviation, particularly with single-pilot operations and lower experience levels, frequently encounter 'automation surprises' due to a lack of clear understanding of autopilot system modes, actions, and future intentions, which complicates safe aircraft operations.
Innovation Solution
An apparatus and method providing an autopilot control interface to activate and set aviation function parameters, along with an autopilot status interface that displays the operational mode, current status, anticipated actions, and supplemental cues to enhance pilot awareness, including previews of targets and progress indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the autopilot system provides detailed information about operational modes and anticipated actions, then pilot awareness and understanding are improved, but the device complexity increases
Solution Approach 1:
The autopilot interface is segmented into distinct functional areas: operational mode display, current status display, anticipated actions display, and target preview display. Each segment presents specific information separately, preventing information overload while maintaining comprehensive awareness. The segmentation allows pilots to process information in manageable chunks rather than facing a wall of undifferentiated data.
Solution Approach 2:
The system displays anticipated actions before they are executed, allowing pilots to prepare mentally for upcoming autopilot maneuvers. This preliminary information presentation includes previewing target parameters and upcoming mode changes, enabling pilots to verify the autopilot's intentions before they affect aircraft operation, thereby reducing automation surprises.
2Reliability
If the autopilot system displays comprehensive status information and anticipated actions, then automation surprises are reduced, but the ease of operation decreases due to increased information processing requirements
Solution Approach 1:
The interface employs color-coding to differentiate between operational modes, status conditions, and anticipated actions. Different colors or color intensities indicate the priority or significance of various information elements, allowing pilots to quickly scan and comprehend the autopilot state without processing every text element. This visual encoding reduces cognitive load while maintaining comprehensive information presentation.
Solution Approach 2:
The system transitions from traditional text-only or simple symbolic displays to a multi-dimensional visual presentation that includes graphical targets, spatial relationships, and layered information displays. By adding visual dimensions beyond simple text, the interface conveys complex autopilot intentions more intuitively, reducing the mental effort required to understand system behavior.

AI summary
Methods and apparatus are provided for providing enhanced autopilot mode awareness for a pilot of an aircraft. The apparatus comprises an autopilot control interface that allows the pilot to activate an operational mode of an autopilot system for the aircraft and to set aviation function parameters of the autopilot system. An autopilot status interface is included that displays the operational mode of the autopilot system and a current status of the aviation function parameters that are controlled by the autopilot system, and an indicator of anticipated actions by the autopilot system to control the aviation function parameters.
