Air brakes ( those hinged flaps on the top of the wing) are used to
bleed off speed. I have seen them deployed ( partially, not fully) in
the air as the plane begins to slow down for landing-- ie 20 min befor
landing.-- and yes, I am alive.) On landing they are typically fully
deployed (ie almost perpendicular to the wing). They are certainly
And air brakes are not thrust reversers ( which come out at the back of
the engines to deflect the output in a forward direction.)
