(TFT LCD). As the AT300 provides additional functionality beyond that of the VSI, additional electrical interfaces are required. In addition to an RS232 serial input from a panel mount GPS system, the AT300 requires a single power input from the aircraft power system, and an associated ground connection...
Page 7: Non-Tso Functions
To support this functionality, aircraft barometric altitude data is obtained by measuring ambient pressure via the aircraft static connection, and baro corrections are required to be manually entered through the systems user interface (UI). In addition, the AT300 provides a supplemental display of GPS navigation data, including presentation of the current waypoint and identifier, and the current navigation leg in the moving map display area.

The following colors are used to render the AT300 terrain map based upon the approximate proximity of terrain to the current aircraft baro corrected altitude.
Page 13: Cold Temperature Operations
When on the ground, or during the landing or departure phases of flight, the AT300 will only render terrain that is more than 100’ above the aircraft’s current baro-corrected altitude. Any terrain that is less than 100’...

Page 21: Tso Installation Statement
Limitations When installed in accordance with this installation manual and the limitations that follow, the installation of the AT300 is unlikely to have an appreciable effect on the weight, balance, structural strength, reliability, operational characteristics, or other characteristics affecting the airworthiness of the aircraft, and should therefore be eligible for installation as a minor alteration.
Page 22 The installation decision flow charts that follow are provided as an aid to the installer for ascertaining the eligibility of the AT300 for use in 14 CFR part 23 classes I, II and III aircraft operated under 14 CFR part 91 or part 135 operating rules.
