I think they don't use engines to slow down. I have seen some parts of the wings (like the rear half of the wings..) along its length standing up right ( something like right angle to the direction of motion of plane) putting a lot of resistance to the air while planes need to slow down.
Using the engine to slow down is like using the reverse gear of your car to slow down, which no one does, which never works (because of possible breakdown of the engine) and should not be done to save the engine from damage.

- mhb 18y agoThe engine itself does not change direction. Surfaces are deployed to redirect its thrust forward instead of backward. And that is only done after the plane is on the ground.
- ars 18y agoThey have three things: Those surfaces as you call them. Thrust reversers (basically fins that push over the end of the jet and redirect the thrust forward), and the brakes on the wheels. All planes must (by FAA regs), be able to land without using the thrust reversers (using the brakes instead), but thrust reversers are what's used in normal cases (since it saves wear on the brakes).
