 3.  Fan Exhaust (Fig. 1)
___________
 A.  The fan exhaust is high velocity exhaust exiting the fan or first stage compressor. The fan exhaust provides 78% of the total forward thrust.
 B.  The direction of the fan exhaust is reversed during landing by the thrust reverser to produce additional braking power for the airplane.

4.  Thrust Reverser (Fig. 1)
_______________
 A.  The thrust reverser system reverses the direction of the fan exhaust during landing and braking of the airplane.
 B.  Stowed, the thrust reverser provides a smooth surface for the fan exhaust to produce thrust. Deployed, the thrust reverser redirects the fan exhaust to produce reverse thrust.
 C.  The thrust levers in the flight compartment initiate forward or reverse thrust.
 D.  The thrust levers are connected electrically to the thrust reverser control module which controls the thrust reverser hydraulic actuators.
 E.  The thrust reverser control system synchronizes the deployment of the thrust reverser halves.
 F.  The thrust reverser position indicating system provides visual indication to the flight compartment of thrust reverser position.
