A side-stick or sidestick controller is an

flightdeck. Typically this is found in aircraft that are equipped with fly-by-wire control systems.[1]

The throttle controls are typically located to the left of a single pilot or centrally on a two-seat flightdeck. Only one hand is required to operate them; two handed operation is neither possible nor necessary.

Prevalence

The side-stick is used in many modern military

Airbus A320 and all subsequent Airbus aircraft,[2] including the largest passenger jet in service, the Airbus A380
.

It is also used in new helicopter models such as the Bell 525.

Compared to centre sticks

A side-stick 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". A side-stick arrangement allows HOTAS and increases ejection seat safety for the pilot as there is less interference amongst flight controls.[citation needed]

Comparison of passive and active side-sticks

Passive side-sticks

In the centre stick design, like traditional

Airbus A320 flying from Surabaya to Singapore).[6][7] The "dual input" warning will not activate at very low levels if the EGPWS activates due to its lower priority compared to EGPWS.[8]

Active side-sticks

However a later, significant, development is the 'active' side-stick,

Irkut MC-21.[13] This is the first airliner
to use them.

Such an active side-stick can also be used to increase adherence to a safe flight envelope by applying a force feedback when the pilot makes a control input that would bring the aircraft closer to (or beyond) the borders of the safe flight envelope. This reduces the risk of pilots entering dangerous states of flights outside the operational borders while maintaining the pilots' final authority and increasing their situation awareness.[14]

And yet that is how their latest generations of aircraft are designed. The reason is that, for the vast majority of the time, side-sticks are superb.
