,.using.inputsfrom.the.FMGC,.controls.thrust based.on.airplane.speed, altitude.and configuration..The.throttles do.not.move when the.Autothrottle.System.is in use. The.system is armed.in.flight by pushing.the.A/THR.switch on.the.FCU.when.the.throttles are.not in the engagement range.
Transmit signals to.the.FADEC,.which computes and.displays.the.thrust rating.limit and.EPR..The.throttle.can.only.be.moved manually..There.are.five lever positions define by.stops or.detents:
Reverse.Idle,
Forward.Idle,
Climb.(CL),
Continuous Thrust.(FLX/MCT)
and.TakeOff./.Go.Around.(TO/GA)

Autothrottle.Disconnect.Switches.(.Red Buttons.)
When pressed, disconnects the.autothrottle system.
Select.Reverse.Thrust.by.overriding.the.stop .
fitted.at.the FWD.IDLE.position..The.stop.is reset.when.the.throttle.is selected.back.to forward.thrust.
Pitch Trim.Wheels
Provides.mechanical control of horizontal stabilizer trim..Trim.wheels have.priority over electrical control..Use.of trim.wheels does not disconnect the.ELACs,.as the.override mechanism ensures.that the.computers.remain synchronized.with.the.manually selected position.
Trim wheels must be.utilized.when.pitch.direct law.is.in.effect.
Pitch.trim.is automatically.reset.to.0.following touchdown.as the.pitch.attitude.becomes less than.2.5°.
Trim.Position.Scales
Indicate trim.position.in.degrees..Normal.range
is.marked.by.a green.band.
CG Scales
Indicate relation.between.CG.location.and pitch.trim setting.prior.takeoff
