Various dash number VSI/TRA displays are available that provide unique design
characteristics, which include VSI rate filter programming and selection of an
English or metric rate scale.
The VSI/TRA also displays symbology corresponding to traffic in the vicinity of
the aircraft. Threat information is received from the TCAS function on a dedicated
high-speed ARINC 429 bus. The display uses the bearing, altitude, and range
data for each threat to provide an indication of the proximity of the threat.
Allowable (non-illuminated or green illuminated bands) and prohibited (red
illuminated bands) vertical rates are displayed based on information received
from the TCAS function. The VSI/TRA can be pin programmed to provide vertical
speed data only, vertical speed and resolution advisory data, or vertical speed,
resolution advisory and traffic advisory data. Display of the TCAS system fault
status is provided on the VSI/TRA in response to extended TCAS control panel
TEST activation.
