Flight Deck Timer Management System for Pilot Workload Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flight deck systems fragment information related to timing requirements, making it difficult for pilots to manage and recall operational and flight rules effectively, which can lead to increased workload and potential navigation errors.
Innovation Solution
A flight deck timer management system that integrates a control unit, database, display device, input device, communications unit, and flight management system to monitor and display timing characteristics, automatically generating advisories based on predefined rules and timer statuses, thereby reducing pilot workload and enhancing situational awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If timing information is distributed across multiple displays in conventional flight deck systems, then information coverage is comprehensive, but information accessibility and pilot workload are degraded
Solution Approach 1:
The patent consolidates timing information from multiple fragmented displays into a single integrated timer management display. This merging of dispersed timing data across different flight deck displays into one unified interface allows pilots to access all timing requirements in one location, reducing the need to scan multiple displays and thereby reducing workload while maintaining comprehensive information coverage.
Solution Approach 2:
The timer management display serves multiple functions simultaneously: it displays timing information for various flight operations, provides visual advisories when timing thresholds are approached, and integrates with the flight management system. This multi-functional design eliminates the need for separate dedicated displays for different timing functions, consolidating information accessibility while maintaining comprehensive coverage.
2Reliability
If pilots rely on mental recall for timer values and limitations, then system simplicity is maintained, but navigation accuracy and safety are compromised
Solution Approach 1:
The timer management system acts as an intermediary between the flight management system and the pilot. It automatically retrieves timing information from the flight management system, processes it according to predefined rules, and presents it in an easily digestible visual format with advisories. This intermediary function enhances navigation accuracy by eliminating reliance on pilot memory while managing complexity through automated processing rather than requiring complex pilot cognitive processing.
Solution Approach 2:
The system provides visual feedback through advisories that automatically appear when timing thresholds are approached or exceeded. This feedback mechanism enhances reliability by alerting pilots to critical timing situations without requiring them to actively monitor and recall all timer values, thereby improving navigation accuracy while maintaining manageable system complexity through intuitive visual cues.
3Reliability
If multiple timers and timing rules are monitored simultaneously, then operational completeness is improved, but information management complexity increases
Solution Approach 1:
The timer management display segments and organizes multiple timing information elements into distinct, clearly labeled components. Each timer and its associated rules are presented as separate manageable units with visual hierarchies, allowing pilots to comprehend multiple timing requirements simultaneously without being overwhelmed by the overall complexity. This segmentation maintains operational completeness while making information management tractable.
Solution Approach 2:
The display dynamically adjusts its presentation based on which timers are currently active and their proximity to thresholds. Timing information that is critically important receives enhanced visual prominence through advisories and color-coding, while less critical information is presented in a more subdued manner. This dynamic adaptation allows the system to monitor multiple timers completely while managing complexity by adapting the information presentation to current operational needs.

AI summary
A flight deck timer management system includes a database storing conditions representing a first monitoring mode defining at least a first rule, a first timing characteristic defining a first time period for compliance with the first rule, and a first advisory value relative to the first time period at which a first advisory is initiated. A control unit is configured to identify input states based on the input data, and to evaluate the input states in view of the first monitoring mode conditions. When the input states trigger the first monitoring mode, the control unit evaluates the input states in view of the first rule, initiates a first timer based on the first timing characteristic, monitors a first timing status of the first timer relative to the first advisory value, and generates display commands representing the first advisory when the first timer status reaches the first advisory value.
