THE MANUAL
This manual is intended to determine a proper installation of the AIS-380 FUEL FLOW ADAPTER. Installation
instructions should be read and followed.

PRODUCT DESCRIPTION
The AIS 380 Fuel Flow is a product designed to provide fuel flow on a digital output bus to a display or GPS
receiver that can receive ARINC 429 or RS-232. The AIS Fuel Flow receives a digital frequency signal from a
fuel transducer or equivalent, ARINC 429 air data, and ARINC 429 heading. The AIS Fuel Flow combines this
data and re-transmits it on an ARINC 429 or RS-232 serial output bus.
The ARINC 429 speed, K-Factor, single/twin engine selection, fuel density, and serial output formats are
configurable using the PC based configuration tool referenced later in this installation manual.
There is an additional RS-422 receive port for a custom application designed specifically for the Bell 412 EPI
engine upgrade STC. This port will receive information regarding the fuel system from an ADIU (Advanced
Digital Interface Unit).
A basic overview is shown below in Figure 1.
