Product Details

The TVI-920 VSI/RA/TA Indicator is an active matrix liquid crystal display, optimized for best viewing angle and contrast. It incorporates all common electrical interfaces for the vertical speed functions and has an air pressure sensor for direct connection to the aircraft static system. The TVI-902D displays conventional vertical speed functions along with traffic information and resolution advisories. Traffic advisories call attention to a developing collision threat by using the TVI-920/920D VSI/RA/TA Indicator, EFIS MFD or Electronic Horizontal Situation Indicator (EHSI), or radar display. This permits mental and physical preparation for a possible maneuver to follow and assists the pilot in achieving visual acquisition of the threatening aircraft. Resolution advisories recommend a vertical speed strategy to provide adequate vertical separation from the threatening intruder. This can be a recommendation to maintain the present vertical speed. The advisory is conditioned to prevent initiation of a maneuver that might expose the aircraft to additional threatening conditions. All resolution advisories are inhibited below 1000 feet agl. The TVI-920 is part of the TCAS-94 system that aids the flight crew by detection the presence of nearby aircraft and providing a warning when the proximity of that aircraft is determined to be a safety threat. The TCAS interrogates the transponders in the surrounding aircraft and uses the replies from those transponders to compute their flight path. From this data, the TCAS evaluates the potential threat.

The TVI-920 has a full color flat panel LCD display that is optimized for wide viewing angles and high contrast displaying conventional vertical speed functions along with traffic information and resolution advisories. The TVI-920 has an air pressure sensor for direct connection to the aircraft static system. The TVI-920 is convection cooled and is packaged in a standard three-inch (3ATI) aircraft instrument case for easy retrofit of conventional vertical speed indicators. The AC-powered TVI-920 has a DC-powered version the TVI-920D that is also available.
