Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots face high workload during aircraft operations, especially in approach phases and emergency situations, due to the need to manually manage exterior aircraft lighting systems, which can divert attention from critical tasks and compromise safety.
Innovation Solution
An autonomous aircraft lighting system that uses aircraft operation parameters like height, rate of descent, and ground speed to automatically select and control the operating state of exterior lights, reducing pilot interaction and workload while enhancing safety through automated emergency signaling.

1Ease of operation
If pilots manually manage exterior aircraft lighting systems, then lighting control is precise and adaptable, but pilot workload increases and attention is diverted from critical tasks
Solution Approach 1:
The lighting system autonomously determines its own operating state by evaluating aircraft operation parameters (height, rate of descent, ground speed, weight on wheels) and automatically selecting appropriate lighting modes without pilot intervention. The system serves itself by making decisions that previously required pilot input, thereby reducing workload while maintaining adaptive lighting control.
Solution Approach 2:
The system continuously monitors aircraft operation parameters and uses this feedback to dynamically adjust lighting states. By establishing a closed-loop control system where lighting decisions are based on real-time aircraft state data, the system achieves adaptive lighting control without requiring continuous pilot attention.
2Reliability
If pilots manually control lighting during emergency situations, then lighting can be precisely adjusted to specific needs, but response time is reduced and safety is compromised
Solution Approach 1:
The system pre-programs lighting responses to various aircraft states and emergency conditions. When an emergency situation occurs, the lighting system immediately executes the pre-determined appropriate lighting state based on the current aircraft parameters, eliminating the time delay associated with manual pilot decision-making and control.
Solution Approach 2:
During emergency situations, the lighting system autonomously determines and executes appropriate lighting states without requiring pilot intervention. This self-service capability ensures immediate lighting adjustment to support safety-critical operations, reducing response time while maintaining reliability through automated decision-making based on real-time aircraft state.
3Productivity
If autonomous control is implemented for lighting system, then pilot workload is reduced and safety is enhanced, but system complexity increases
Solution Approach 1:
The autonomous lighting control system serves multiple functions: it monitors aircraft operation parameters, determines appropriate lighting states, controls lighting output, and adapts to different flight phases and emergency conditions. By consolidating these multiple functions into a single integrated system, the patent reduces overall system complexity while achieving autonomous operation that enhances productivity and safety.

AI summary
A method of autonomously operating an aircraft lighting system is disclosed. The aircraft lighting system includes at least one autonomously operated exterior aircraft light (6, 8, 10, 12, 14, 16, 18, 20, 22), with each of the at least one autonomously operated exterior aircraft light having at least two operating states. The method comprises the steps of determining a momentary value of at least one of a group of aircraft operation parameters consisting of height above ground, rate of descent, ground speed, and weight on wheels; for each of the at least one autonomously operated exterior aircraft light, selecting a particular operating state from the at least two operating states depending on the momentary value of the at least one of the group of aircraft operation parameters; and controlling each of the at least one autonomously operated exterior aircraft light in accordance with the particular operating state selected.
