Terrain Awareness and Warning System (TA WS-B)-Optional (continued)
TAWS-B Page:
The TAWS-B Page is located in the Map Page Group on the MFD.
The TA WS Page is specialized to show terrain, obstacle, and potential
impact point data in relation to the aircraft's current altitude, without clutter
from the base map. Aviation data (airports, VORs, and other NAY AIDs) can
be displayed for reference. If an obstacle and the projected flight path of the
aircraft intersect, the display automatically zooms in to the closest potential
point of impact on the TA WS-B Page.
Aircraft orientation on this map is always heading up unless there is no valid
heading. Two views are available relative to the position of the aircraft; the
°
360
default display and the radar-like ARC (120
adjustable with the RANGE Knob from L to 200 nm, as indicated by the
• map range rings or arcs.
On all pages that display terrain data, the obstacles and terrain are depicted
with the following colors:
• Red - above or within 100 feet below the aircraft altitude.
• Yellow - between 100 feet and 1000 feet below the aircraft altitude.
• Black - more than 1000 feet below the aircraft altitude.
TA WS-B Alerts:
Alerts are issued when tlight conditions meet parameters that are set
within TA WS-B software algorithms. TA WS-B alerts typically employ a
CAUTION or a WARNING alert severity level, or both. When an alert is
issued, visual annunciations are displayed on the PFD and MFD and aural
alerts are simultaneously issued. The TAWS-B Alert Annunciation is shown
at the upper left of the Altimeter tape on the PFD and below the Terrain
Legend on the MFD. If the TAWS-B Page is not displayed at the time, a
pop-up alert appears on the MFD. To acknowledge the pop-up alert:
• Press the CLR Key (returns to the currently viewed page), or
•
• Press the ENT Key (accesses the TA WS-B Page)
Refer to the Cockpit Reference Guide for a list of TA WS-B Alerts .
