IVA 81A/C/D TA/VSI TRAFFIC ADVISORY/VERTICAL
SPEED INDICATOR
The TA/VSI combines the vertical speed instrument with the TA and
RA display functions. Red and green bands around the circumfer-
ence of the screen give RA information. Traffic location is presented
on the face of the display inside of the vertical speed scale.
The TA Select Pushbutton can be wired for either a Traffic Select or
Switchable configuration at time of installation.
In both configurations, when a TA or RA is present all traffic Pop-up
on the display. Pressing the button alternates between showing all
traffic and VSI display only.
When the display is clear of traffic, presence of a new TA or RA
intruder Pop-up all traffic on the display. Without traffic the instrument
operates as a VSI only.
Note: For all NVIS types, when the NVIS mode is selected, the point-
er, border, numerals and the scale graduations which are normally
white will be green.
