2. Air brake (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Air_brake_(aeronautics)

   Often, characteristics of both spoilers and air brakes are desirable and are combined - most modern airliner jets feature combined spoiler and air brake controls. On landing, the deployment of these spoilers ("lift dumpers") causes a significant reduction in wing lift, so the weight of the aircraft is transferred from the wings to the undercarriage.

3. Spoiler (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Spoiler_(aeronautics)

   In aeronautics, a spoiler (sometimes called a lift spoiler or lift dumper) is a device which increases the drag and decreases the lift of an airfoil in a controlled way. Most often, spoilers are hinged plates on the top surface of a wing that can be extended upward into the airflow to spoil the streamline flow.

4. Flight control surfaces - Wikipedia

   en.wikipedia.org/wiki/Flight_control_surfaces

   Air brakes are used to increase drag. Spoilers might act as air brakes, but are not pure air brakes as they also function as lift-dumpers or in some cases as roll control surfaces. Air brakes are usually surfaces that deflect outwards from the fuselage (in most cases symmetrically on opposing sides) into the airstream in order to increase form ...

   en.wikipedia.org/wiki/Talk:Spoiler_(aeronautics)

   Air brakes are inboard spoilers, I don't think there should be just a hard and fast differentiation between air brakes and spoilers. When you are airbraking on the ground you extend both inboard and outboard spoilers, (or the armed hydraulic system does, after it detects weight on wheels in an airliner), if you are spoiling off speed in the air ...

6. Spoileron - Wikipedia

   en.wikipedia.org/wiki/Spoileron

   Spoilerons roll an aircraft by reducing the lift of the downward-going wing.Unlike ailerons, spoilers do not increase the lift and drag of the upward-going wing. A raised spoileron increases the drag on the down-going wing where it is deployed, causing the aircraft to yaw in the direction of the turn.

7. Flap (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Flap_(aeronautics)

   A spoiler is much larger than a Gurney flap, and can be retracted. Spoilers are usually installed mid chord on the upper surface of the wing, but may also be installed on the lower surface of the wing as well. Air brakes are used to increase drag, allowing the aircraft to decelerate rapidly. When installed on the wings they differ from flaps ...

8. Spoiler (car) - Wikipedia

   Pickup truck bed spoiler: This attaches only to the top of the truck bed rails near the rear. Used with a bed cover, this spoiler is intended to reduce the air profile of the steep drop-off from the tailgate. Pickup truck cab spoiler: This works the same as above, except focusing on the drop-off from the truck's cab to the cargo bed.
