How does an airplane stay stable in the air?

to keep a plane stable in the air it has different control surfaces or panels to allow the pilot to adjust the position of the plane in the air. Some modern fighter jets such as the Eurofighter Typhoon are deliberately made to be unstable so the jet is more maneuverable or agile in the air. planes like this have powerful computers to adjust the flaps and control panels hundreds of times a second to keep the plane stable when it's flying normally.
