A spoiler<\/em> <\/strong>is a flight control device located only on the top surface of an aircraft wing. It is used to reduce, or \u201cspoil\u201d some of the wing\u2019s lift. It also creates drag.<\/span><\/p>\n

A speedbrakes<\/strong> <\/em>is a device that can be located anywhere on the aircraft. Unlike a spoiler, it only produces drag, although usually a lot more of it.<\/span><\/p>\n

However on some aircraft, the same flight control panel surfaces on top of the wing can do double duty as both a spoiler and a speedbrakes, depending upon the circumstances and pilot control.<\/span><\/p>\n

Spoilers can be subdivided into four categories:<\/span><\/p>\n

 <\/p>\n

Ground Spoilers (AKA Lift dumpers)<\/span><\/strong><\/span><\/p>\n

These deploy when an aircraft lands, or if a takeoff is rejected. Depending upon the aircraft type, they deploy either manually or automatically.<\/span><\/p>\n

They pop up to their maximum angle, destroying lift to keep the full weight of the aircraft on the runway and produce aerodynamic drag, both helping it slow.<\/span><\/p>\n

 <\/p>\n

Flight Spoilers<\/span><\/strong><\/span><\/p>\n

These can be the same panels as the ground spoilers, or they can be separate.<\/span><\/p>\n

They are programmable by the pilot to varying degrees of angle, and they are symmetrical on both wings.<\/span><\/p>\n

They essentially do the same thing as speedbrakes, with the added advantage of reducing wing lift.<\/span><\/p>\n

Roll Spoilers<\/span><\/strong><\/p>\n

On some aircraft to aid turning, the spoiler panels on the side of turn direction will deflect slightly in conjunction with the ailerons.<\/span><\/p>\n

In fact in some aircraft without ailerons, spoilers are the main turn and roll flight controls.<\/span><\/p>\n

 <\/p>\n

Direct Lift Control (DLC)<\/span><\/strong><\/p>\n

On a few aircraft, spoilers are used in conjunction with power settings and nose attitude to maintain a proper glide slope, and better engine response. Upon initiating DLC, the spoilers pop up only a few degrees, necessitating a slightly higher power setting.<\/span><\/p>\n

Then by means of a thumbwheel, a pilot can either increase or decrease the spoilers\u2019 angle of deflection, thus instantaneously increasing or decreasing lift to control his glide path.<\/span><\/p>\n
