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 for 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 reverser control system initiates and synchronizes the deployment of the thrust reverser sleeves.
 E.  The thrust reverser indicating system provides visual and tactile indication to the flight compartment of thrust reverser position.
