AIR DATA SYSTEM
DESCRIPTION
Air data information is sensed by the pitot static system and total air temperature (TAT) probe. This data is processed by
the air data computers (ADCs) and sent to the flight displays, IAPS, and several aircraft systems. Cockpit controls include
the BARO SET knob, ADC REVERSION switch, several flight guidance panel (FGP) controls, and the reference speeds
(REFS) menu settings.
COMPONENTS AND OPERATION
Airspeed information displayed on the PFD include:
- Airspeed display
- Reference speeds
- Low/high/speed cues
- Airspeed trend vector
- Mach number display

reference speeds are set through the REFS push button on the display control panel.
The SPEED knob, on the flight guidance panel (FGP) is used to set the cyan speed bug on the airspeed display.
AIRSPEED DISPLAY
The airspeed display is a moving vertical tape, with the digital display of the current airspeed in the fixed window. The
display is located to the left of the attitude sphere on the PFDs. The current Mach number is indicated as a digital value
at the bottom of the tape. If the aircraft speed is greater than 0.4 Mach, the crew can select a Mach tape, which replaces the
airspeed tape.
The indicated airspeed tape has an airspeed range from 40 to 400 kt. The tape has a scale that is marked every 5 kt and
numerically marked every 20 kt.
REFERENCE SPEEDS
The takeoff reference speeds are presented on the speed scale as a V
1
, V
R
, V
2
, and V
T.
Manually set V speed values show
in cyan characters; optional FMS-calculated V speed characters show in magenta.
The FGP SPEED knob is used to select and set the airspeed reference bug to the desired speed on the airspeed tape. The
speed bug is located beside the selected speed with a ± 5 knot deviation indication.
When the center of the SPEED knob is depressed, the speed reference toggles between Mach and speed.
LOW/OVERSPEED/FLAP SPEED CUES
A low speed cue indicates a calculated airspeed of 1.06 V
S
. It appears from the lower portion of the airspeed scale and is
displayed as a solid red line that changes to an expanded alternating red and black band when the aircraft is within a few
knots of activating the stickshaker. The top of this cue visually represents the speed at which the stick shaker will activate.
An overspeed cue is provided to indicate the maximum operating speed. It appears in the upper portion of the airspeed scale
and is displayed as a solid redline that changes to an alternating red and black band when approaching overspeed.The over-
speed cue reduces to the flap operating speed limit when the flaps are extended.
TREND VECTOR
The airspeed trend vector originates from the tail of the indicated airspeed arrow. The magenta trend vector moves verti-
cally in response to the aircraft acceleration or deceleration indicating the speed predicted in the next 10 seconds.
