Aeroplane Ground Navigation Extrapolation for Runway Incursion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for assisting airplane ground navigation at airports are inadequate in preventing runway incursions, particularly in low visibility conditions, as they do not provide comprehensive information about the aircraft's surroundings, leading to potential collisions with other aircraft or obstacles.
Innovation Solution
A method and device that automatically determine the extrapolated position of an airplane's nose based on current parameters such as position, speed, direction, and yaw rate, comparing it to predetermined prohibited zones to emit warning signals when a risk of incursion is detected, allowing pilots to take preventive measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the pilot monitors the display screen showing airport map and traffic, then the pilot can obtain information about the environment, but it requires the pilot to look very often and regularly at the display screen, increasing workload and distracting from piloting tasks
Solution Approach 1:
The system performs preliminary action by automatically calculating and predicting the aircraft's future position and comparing it with prohibited zones in advance, before the pilot needs to check the display screen. This automated preliminary monitoring eliminates the need for the pilot to continuously check the display, reducing workload while maintaining situational awareness.
Solution Approach 2:
The system implements self-service by autonomously performing the monitoring function - the device automatically determines current parameters, calculates extrapolated positions, compares with prohibited zones, and generates alerts without requiring pilot intervention or continuous attention to the display screen.
2Loss of information
If the system uses airport map display to show position and traffic, then the pilot can see the environment, but it is difficult to detect in advance a risk of intrusion on a runway since the future position of the aircraft depends on speed and direction which are difficult to evaluate by looking at the display screen
Solution Approach 1:
The system performs preliminary calculation of the aircraft's extrapolated position by automatically computing future position based on current parameters (speed, direction, yaw rate) and comparing it with prohibited zones in advance, making future position evaluation straightforward without requiring pilot interpretation of display information.
Solution Approach 2:
The system replaces the mechanical/visual evaluation method (pilot visually assessing position and speed from display screen) with an automated computational system that automatically determines current parameters, calculates extrapolated positions, and compares with prohibited zones, significantly reducing the difficulty of detecting incursion risks.
3Reliability
If the system only provides information about landing gear and immediate area, then the pilot can prevent gear from hitting obstacles, but the system does not provide information on the whole runway or extended area, which is dangerous in poor visibility when another aircraft may be on the same runway
Solution Approach 1:
The system implements multi-functionality by integrating multiple monitoring functions: it determines current parameters of the aircraft, calculates extrapolated positions, compares with prohibited zones including runways and taxiways, and provides comprehensive alerts. This universal approach covers both immediate gear area safety and extended runway/taxiway area monitoring, eliminating information gaps about other aircraft.
4Reliability
If the system automatically determines extrapolated position and compares with prohibited zones, then the pilot is informed of runway incursion risk, but the system complexity increases with multiple sensors and calculation processes
Solution Approach 1:
The system achieves runway incursion prevention through a multi-functional device that integrates determination of current parameters (position, speed, direction, yaw rate), automatic calculation of extrapolated position, comparison with prohibited zones, and alert generation. This universal approach consolidates multiple functions into a single integrated system, managing complexity while maintaining high reliability.
