Content: Only one hand is required to operate it; two hand operation is neither possible nor necessary. The side-stick is used in many modern military fighter aircraft, such as the F-16 Fighting Falcon, Mitsubishi F-2, Dassault Rafale, and F-22 Raptor, and also on civil aircraft, such as the Sukhoi Superjet 100, Airbus A320 and all subsequent Airbus aircraft, including the largest passenger jet in service, the Airbus A380 . It is also used in very new helicopter models such as the Bell 525 . This arrangement contrasts with the more conventional design where the stick is located in the centre of the cockpit between the pilot's legs, called a " centre stick ". In the centre stick design, like traditional airplane yokes, both the pilot's and co-pilot's controls are mechanically connected together so each pilot has a sense of the control inputs of the other. In typical Airbus side-stick implementations, the sticks are independent, the so-called 'passive' side-stick. The plane's computer either aggregates multiple inputs or a pilot can press a "priority button" to lock out inputs from the other side-stick. However, if both side-sticks are moved in different directions (regardless of which pilot has priority), then both inputs are cancelled out and an aural "dual input" warning sounds. Examples of this occurring include the 2009 crash of Air France Flight 447 (an Airbus A330 flying from Rio de Janeiro to Paris ), the 2010 crash of Afriqiyah Airways Flight 771 an Airbus A330 from flying Johannesburg to Tripoli and the 2014 crash of Indonesia AirAsia Flight 8501 (an Airbus A320 flying from Surabaya to Singapore ).
