negative stability

Everyone there knew what the term "negative stability" meant.

"Most high- tech tactical aircraft today have negative stability."

It incorporated negative stability and fly-by-wire controls with four analog computers.

Aircraft with negative stability are designed to deviate from controlled flight and thus be more maneuverable.

Kites can have positive, neutral or negative stability, in all axes of control, in the same fashion as aircraft.

The aircraft has negative stability.

"The aircraft had negative stability," Franks said, hooking his thumbs behind his belt and warming to the subject.

Negative stability, on the other hand, meant that once the plane was displaced from wings-level, it would tend to increase the rate of displacement if the controls were released.

Everyone there knew what the term "negative stability" meant If the pilot released the controls, a plane with positive stability would tend to return to a wings-level, stable condition.

The main wing incorporated forebody strakes to enhance vortex generation for high angle of attack maneuverability, negative stability for improved subsonic lift and reduced supersonic drag.

Kites with positive stability tend to return to a stable state automatically, whereas those with neutral or negative stability require control inputs to return the kite to the required position or attitude.

"There is a lot of panicky conversion going on now among wealthy Chinese, and while some of that will taper off when there is stability, even negative stability in China, it won't stop," he added.

High performance aircraft that have FBW controls (also called CCVs or Control-Configured Vehicles) may be deliberately designed to have low or even negative stability in some flight regimes, the rapid-reacting CCV controls compensating for the lack of natural stability.
