Aircraft Flight Path Control Device for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft control systems are inadequate in handling unexpected events such as communication failures or obstacles that deviate an aircraft from its instructed flight path, leading to potential safety risks.
Innovation Solution
A control device and method that set primary and secondary flight paths for each aircraft, allowing the aircraft to switch to a secondary path when predetermined conditions, such as obstacles or communication failures, are met.

Engineering Contradiction Analysis
1Reliability
If the control station resets the flight path for aircraft around a deviating aircraft, then collision avoidance is achieved, but the resetting process takes time causing a temporary reduction in safety
Solution Approach 1:
The system pre-calculates and stores multiple alternative flight paths (secondary paths) in advance for each aircraft. When an aircraft deviates from its primary path or a communication failure occurs, the control station can immediately assign a pre-prepared alternative path without needing to recalculate from scratch, thus eliminating the safety gap during path resetting
Solution Approach 2:
The patent prepares backup flight paths beforehand as a cushion against potential failures. These alternative paths act as a safety buffer that can be activated immediately when abnormal events occur, preventing the system from entering a vulnerable state during path recalculation
2Reliability
If the control station updates the flight path upon detecting abnormal events, then safety is maintained, but communication failure interrupts or delays the update process
Solution Approach 1:
The aircraft is equipped with autonomous capability to detect abnormal events (such as obstacles or communication failures) and independently select from pre-stored alternative flight paths. This self-service mechanism ensures that flight path updates can occur without relying on continuous communication with the control station, maintaining safety even during communication interruptions
Solution Approach 2:
Multiple alternative flight paths are pre-calculated and stored in the aircraft's memory before flight. When communication failure occurs, the aircraft can immediately access and execute these pre-prepared paths without needing real-time communication with the control station, thus preventing information loss from affecting safety

AI summary
Provided are a control device and a control method by which an airplane can maintain flight while maintaining a high level of safety, even if there is a conceivable abnormal event such as a communication failure or an obstacle. This control device is for an airplane, the control device being characterized by: comprising a setting unit that sets a main flight route, which is a normal flight route, and at least one secondary flight route, for each of a plurality of airplanes, and a management unit that prevents interference between a given main flight route and a given secondary flight route, and a main flight route and secondary flight route of another airplane; obtaining information about an airplane or the surrounding airspace; and when the information matches a preset prescribed condition, permitting the airplane to operate using the secondary flight route.
