.
S.-Minimum.Slat Retraction.Speed.-Appears in.green.next.to.the.minimum speed.for selecting.position 0.when.the FLAPS.selector.is in.position.1. Computed.by the.FACs.
.
1.-Decision.Speed.(V1).-Appears in blue.next.to.the speed.entered.by.the crew through.the.MCDU. When.out of indication.range, appears.on.upper part.of.scale..Disappears.after.lift-off.
.
Actual Airspeed Reference.Line
Indicates the.actual airspeed.where.the.scale value.moves in.front.of.the.line..Airspeed indication.starts.from 30.knots.
Speed.Trend Arrow
Starting.from.the.airspeed.reference line, points to.the.speed.value.which.will.be.attained in.10.seconds.if the.acceleration.remains constant. Appears only.when.speed.difference is greater.than.two.knots. Disappears when speed.difference.is less than.one.knot, or.if FACs.fail
Target.Airspeed Pointer
Points to.the.target.airspeed.value.or the airspeed.corresponding.to.the.target Mach number..The.pointer.is.magenta.when.the
12.11.06 -.44-
target airspeed.is the.value.computed.by.the FMGC.in.managed.speed.mode..The.pointer is blue.when.the.target airspeed.is manually entered.on.the.FMGC or.manually entered.on the.FCU..When.the.target.airspeed.is out of the.speed.tape.range, the.target speed.value.is displayed.above.or below the.speed.tape.in numeric.form.
Minimum Selectable.Speed (VLS)
Represents 1.13.stall speed.(VS) during takeoff or.following.touch and.go.as computed by.the.FACs.
Alpha.Protection Speed
Represents the.speed.corresponding.to.the angle.of attack.at which.alpha.protection activates, as computed.in.pitch.normal.law by the.FACs.
Mach Number
Displays.when.number.is greater.than..5.
ILS Information
The.following.appears.when.an.ILS.frequency and.course.have.been.selected.in.the.MCDU and.when.the.ILS.switch.on.the.EFIS control panel is pushed:
.
ILS.identification.as decoded.from.the ILS.receiver.
.
ILS.frequency.
.
DME distance.if a.DME.is.co-located.
PFD.Attitude Indications
Fixed.Airplane.Symbol
Pitch.Scale
Provides graduations between.80°.nose.up and.80°.nose.down.with.2.5°.increments between.10°.nose.down.and.30°.nose.up.
Roll.Index
Points to.angle.of bank on.roll.scale.
Roll.Scale
Provides graduations at 0, 10,.20, 30 and.45 degrees of bank.
Side.Slip.Index./.Beta.Target
Indicates lateral.acceleration.on the.ground and.side.slip.in.flight as provided.by ADIRS. Reaches.stop.at .3Gs.
