FMS/Man in either MAN or FMS.
When the selected airspeed is offscale,
the airspeed bug is located at the appropriate end of the
airspeed tape and one half of the symbol is masked.
FMS Selected Airspeed
The FMS selected airspeed is displayed in place of the selected airspeed readout with an “F” label
in large font, with a resolution of 1 kt and has a range of 0 kt through 900 kt inclusively. The FMS
speed is displayed when:
· IAS is valid, and
· FMS speed is valid, and
· IAS FMS/Man indicates FMS, and
· FMS speed reference is speed.

Mach Readout
The Mach readout is located below the airspeed tape when the Mach exceeds 0.450 M and
remains greater than 0.400 M. The Mach readout has a resolution of 0.001 M.
Selected Mach Readout
The selected Mach readout is displayed in large font in place of the selected airspeed readout and
has a resolution of 0.01 M. The selected Mach is displayed when:
· Airspeed tape is displayed, and
· IAS FMS/Man indicates MAN, and
· Selected airspeed type is Mach and less than MMO.
NOTE
MMO is displayed when the selected airspeed is at MMO.
FMS Selected Mach Readout
The FMS selected mach readout is displayed above the airspeed tape with a letter “F”. It is
displayed in large font in place of the selected airspeed readout, and has a resolution of 0.01 M.
The FMS readout is displayed when:
· Airspeed tape is displayed, and
· IAS FMS/Man Indicates FMS, and
· Selected airspeed type is Mach.

VMO/MMO Annunciation
The VMO indication is displayed in large font, instead of the selected airspeed when the IAS
FMS/Man indicates MAN and the selected airspeed type is IAS.
The MMO indication is displayed in large font, instead of the selected Mach when the airplane
exceeds VMO/MMO and the IAS FMS/Man indicates MAN and the selected airspeed type is Mach.
VMO Thermometer
The VMO thermometer extends from the Vmo to the top of the airspeed tape. The following
airspeeds are used instead of the VMO in specific cases:
· VF3 (185 knots) when the flap angle is greater than 17°.
· VF2 (210 knots) when the flap angle is between 7° and 17°.
· VF1 (210 knots) when the flap angle is between 1° and 7°.
· VSO (225 knots) when the slat angle is greater than 1° and the flap angle is lower than 1°.
· VLE (250 knots) when the slat angle is lower than 1°, the flap angle is lower than 1° and at
least one of the landing gear is down and locked.

AOA Margin Indication (AMI)
The AMI displays the margin available between the current AOA and the stall AOA as defined by
the Stick Shaker.
The AMI is displayed in relation to the position of the FPV; below 0.70 Mach it is displayed when
the aircraft AOA vane is within 5 degrees of Stick Shaker activation and it is removed when a
margin of more than 6 degrees is reached. At 0.84 Mach and above the AMI is displayed when the
aircraft AOA vane is 2.5 degrees from Stick Shaker activation and it is removed when a margin of
more than 3 degrees is reached. Between 0.70 and 0.84 Mach a linear range is used to display
the AMI between 5 degrees and 2.5 degrees respectively.
The AMI is displayed above the FPV at half distance equal to the margin. If the symbol is
superimposed to the FPV the aircraft shaker is activated.
