Every aircraft, whether an airplane, helicopter or rocket, is affected by four opposing forces: Thrust, Lift, Drag and Weight (Fig. 1). Control surfaces, such as the rudder or ailerons, adjust the direction of these forces, allowing the pilot to use them in the most advantageous way possible.
What are the 4 main flight controls?
The primary controls are the ailerons, elevator, and the rudder, which provide the aerodynamic force to make the aircraft follow a desired flightpath.
What are the control surfaces on a plane?
Movement of any of the three primary flight control surfaces (ailerons, elevator or stabilator, or rudder), changes the airflow and pressure distribution over and around the airfoil.
What flight control surface causes the plane to roll?
Ailerons. Ailerons are the primary flight control surfaces that move the aircraft about the longitudinal axis. In other words, movement of the ailerons in flight causes the aircraft to roll. Ailerons are usually located on the outboard trailing edge of each of the wings.

What are the controls in a cockpit?
Yoke, Side Stick, Center Stick The yoke is the airplane’s “steering wheel.” The yoke controls the airplane’s ailerons. In simplest terms, it allows the pilot to move the airplane “up,” “down,” “over left,” and “over right.”Twistingthe yoke side to side controls roll and pitch.
What are the three primary flight control surfaces of an aircraft?
Primary flight controls are required to safely control an aircraft during flight and consist of ailerons, elevators (or, in some installations, stabilator) and rudder.
What is meant by control surface?
Definition of control surface : a movable airfoil designed to change the attitude of an aircraft.
Is a spoiler a control surface?
Definition. Spoilers and Speedbrakes are secondary flight control surfaces that can be deployed manually by the pilot or, under certain circumstances, that extend automatically. Speedbrakes are purely drag devices while spoilers simultaneously increase drag and reduce lift.
Can an aircraft fly without flight control surfaces?
Researchers in the UK have flown the first aircraft that can maneuver without conventional control surfaces or flaps. In place of elevators and ailerons, the aircraft uses jets of air along the back of the wing to control lift.
Which control surface does the pilot use to control pitch?
Transverse axis Rotation about this axis is called pitch. Pitch changes the vertical direction that the aircraft’s nose is pointing. The elevators are the primary control surfaces for pitch.
Which is the secondary control surface?
Secondary control surfaces include spoilers, flaps, slats, and air brakes. Spoilers, no not the movie or automobile kind, are often called lift dumpers as they are used to reduce lift by disrupting the airstream above the wing. Spoilers allows glider pilots to reduce in altitude without increasing airspeed.
Why is it called yaw?
Yaw is one such word. Its origin isn’t exactly known, but it began turning up in print in the 16th century, first as a noun (meaning “movement off course” or “side to side movement”) and then as a verb.
What are the primary and secondary flight controls?
Flight control surfaces are devices that allows a pilot to adjust and control the aircraft’s altitude by using aerodynamics. Main control surfaces include ailerons, rudders, and elevators. Secondary control surfaces include spoilers, flaps, slats, and air brakes.
What are the 6 basic flight instruments?
All airplanes have six basic instruments: airspeed indicator, attitude indicator, altimeter, turn coordinator, heading indicator, and vertical speed indicator.
How are primary flight controls controlled?
Primary Flight Controls The ailerons and elevator are connected to the aircraft’s “stick” or “yoke”, while the rudder is controlled through rudder pedals located in the footwell.
How does a flight control system work?
A manual flight control system uses a collection of mechanical parts such as pushrods, tension cables, pulleys, counterweights, and sometimes chains to transmit the forces applied to the cockpit controls directly to the control surfaces. Turnbuckles are often used to adjust control cable tension.

How many controls does a plane cockpit have?
Below it are two knobs; the forward one controls the brightness of the map light (the red-capped light on the left side of the image). The rear knob has no function. Behind the knobs is the pilot’s emergency oxygen mask.
