(1) Functional Description and Operation
The VSI/TRA has three functions. It continuously displays rate of climb or rate of
descent. Traffic information is displayed and resolution advisory information is
displayed against vertical speed to allow the flight crew to avoid threats.
The vertical speed display is generated from signals applied directly to the
indicator. The VSI/TRA is designed to be used in place of a conventional vertical
speed indicator. Four possible sources exist for vertical speed data including
ARINC 429 data, dc analog signals in accordance with ARINC 575
(approximately 500 millivolts per 1000 feet per minute or per 304.8 meters per
minute), ac analog signals in accordance with ARINC 565 (approximately 250
millivolts per 1000 feet per minute or 304.8 meters per minute), and ARINC 429
signals from the ACSS Pressure Transducer Module. The VSI/TRA computes
vertical rate from electrical static pressure when a remote static sensor is used.
These four program pin selectable configurations provide compatibility with most
aircraft.
