Total Air Temperature Probe
An electrically-heated total air temperature (TAT) probe is mounted on the fuselage beneath the copilot side window. The probe measures the TAT, and supplies this information to the air data computers (ADC 1 and ADC 2).

Air Data Computer
Each ADC receives pitot static pressures and temperatures from the pitot, static and TAT probes and pilot-selected inputs. Pilot-selected input cockpit controls include the BARO knob, ADC reversion switch, several FCP control selections, and the reference speeds (REFS) menu settings.
This data is processed by the air data computers (ADCs), and sent to the EFIS displays, IAPS, and several aircraft systems.
The ADC calculates the following air data system parameters:
.
Pressure altitude and barometric-corrected altitude;

.
Static air temperature (SAT);

.
Total air temperature (TAT);

.
Temperature variations from standard (ISA);

.
Vertical speed;

.
Indicated airspeed;

.
Mach number;

.
True airspeed;

.
IAS reference;

.
Vertical speed reference;

.
Airspeed trend vector;

.
Transition FL alert (default FL180);

.
Static source error correction;

.
Maximum speed (VMO and MMO); and

.
Overspeed warning.


AIR DATA SYSTEM INDICATIONS


Description
The PFD display presents airspeed, altitude and vertical speed indications. Airspeed information is displayed on the left side of the PFD. Altitude and vertical speed information are displayed on the right side.
Airspeed
The pilot can choose either an IAS or Mach airspeed tape as the primary indication of speed. Both speed tapes provide similar information. The airspeed display is a moving vertical tape, with the digital display of the current airspeed in the fixed window.

IAS Airspeed Display
The indicated airspeed tape has an airspeed range from 40 to 400 kt. The tape has short tick marks every 5 knots, long tick marks every 10 knots, and is numerically marked every 20 knots.

Mach Number and Mach Display
When the IAS airspeed tape is displayed, and the equivalent Mach is 0.40 or greater, a green 3 digit readout of current Mach number is displayed at the bottom of the tape. A grey "M" indicator also appears in front of the readout.
