2.2 SUPPLEMENTAL FLIGHT DATA
NOTE: Pressing the DFLTS Softkey (a second-level PFD softkey) turns off metric Altimeter display, the Inset Map, and wind data.
In addition to the flight insturments, various supplemental information is also displayed on the PFD, including a generic timer, the Outside Air Temperature (OAT), wind data, the system time, and Vertical Navigation (VNV) indications.
GENERIC TIMER
The Timer/References Window contains a generic timer, which can be set to count up or down from a specified time (HH:MM:SS). When the countdown on the timer reaches zero the digits begin to count up. If the timer is reset before reaching zero on a countdown, the digits are reset to the initial value. If the timer is counting up when reset, the digits are zeroed.
Figure 2-31 Timer/References Window
Setting the generic timer:
1)Press the TMR/REF Softkey.
2)Turn the large FMS Knob to select the time field (hh/mm/ss).
3)Use the FMS Knob to enter the desired time and press the ENT Key.
4)With the UP/DN field highlighted, turn the small FMS Knob to select the timer counting direction.
5)Press the ENT Key.
6)With ‘START?’ highlighted, press the ENT Key to start the timer. The field changes to ‘STOP?’.
7)To stop the timer, press the ENT Key with ‘STOP?’ highlighted. The field changes to ‘RESET?’.
8)To reset the timer, press the ENT Key with ‘RESET?’ highlighted. The field changes back to ‘START?’ and the digits are reset.
9)To remove the window, press the CLR Key or the TMR/REF Softkey.

OUTSIDE AIR TEMPERATURE
The Outside Air Temperature (OAT) is displayed in degrees Celsius (°C) by default in the lower left of the PFD under normal display conditions, or below the true airspeed in reversionary mode.

WIND DATA
Wind direction and speed (relative to the aircraft) can be displayed in a window to the upper left of the HSI. When the window is selected for display, but wind information is invalid or unavailable, the window shows “NO WIND DATA”. Wind data can be displayed in three different ways:
•Longitudinal and lateral components (Option 1)
•Total wind direction and speed (Option 2)
•Total direction with head and crosswind speed components (Option 3)

Option 2 |
Option 3 |
No Data |
Figure 2-32 Wind Data
Displaying wind data:
1)Press the PFD Softkey.
2)Press the WIND Softkey to display wind data below the Selected Heading.
3)Press one of the OPTN softkeys to change how wind data is displayed.
4)To remove the window, press the OFF Softkey.

SYSTEM TIME
The system time is displayed in the lower right corner of the PFD. Three display formats are available, local 12-hr, local 24-hr, and Coordinated Universal Time (UTC). Time and date are obtained from the GPS satellites and cannot be changed, although a time offset may be entered (±HH:MM) for local times.
Figure 2-33 System Time
Configuring the system time:
1)Select the AUX - System Setup Page using the FMS Knob.
2)Press the FMS Knob to activate the cursor. ‘Time Format’ is highlighted.
3)Turn the small FMS Knob to select the desired format.
4)Press the ENT Key to confirm selection. ‘Time Offset’ is highlighted (for local time formats).
5)Enter the desired time offset (±HH:MM) for local time formats.
6)Press the ENT Key to confirm selection.

VERTICAL NAVIGATION (VNV) INDICATIONS
When a VNV flight plan has been activated, VNV indications (VNV Target Altitude, RSVI, VDI) appear on the PFD in conjunction with the “TOD within 1 minute” message (Figure 2-35) and “Vertical track” voice alert. See the GPS Navigation and AFCS sections for details on VNV features. VNV indications are removed from the PFD according to the criteria listed in Table 2-2.
