What is the name of the flight control system that was developed to relax aircraft stability for improved maneuverability?

The flight control system designed to relax an aircraft's stability for enhanced maneuverability is known as fly-by-wire. This system utilizes electronic controls and computers to manage the aircraft's flight controls instead of traditional mechanical linkages. By allowing the aircraft to operate with less inherent stability, fly-by-wire systems enable more agile maneuvering, which is particularly beneficial in modern aircraft operations, where performance demands have increased significantly.

Fly-by-wire systems can include various software-based enhancements that optimize handling and responsiveness while still maintaining safety. This technology can adapt to different flight conditions or pilot inputs, contributing to a more responsive and controlled flying experience. The potential for improved maneuverability is a key factor in optimizing mission performance, particularly for military applications or complex flight scenarios.

Other options, such as StabiliTrak, auto-pilot, and active control, serve different purposes. StabiliTrak is primarily a vehicle stability control system, auto-pilot refers to automation of flight control during cruise or steady phases, and active control systems typically involve real-time adjustments to enhance overall performance but may not specifically focus on relaxing stability in the same way that fly-by-wire does.
