Archangel Receives FAA TSO Approval for its AFC001 Automatic Flight Control

Archangel Systems Inc. announced today it has received FAA TSO C9c approval to manufacture its Automatic Flight Control (AFC001). The AFC receives ARINC 429 data and converts it to 2 wire, isolated DC outputs, suitable to drive most autopilot servos/servo amps.  The AFC also creates error signals for heading, roll, pitch, and altitude to enable attitude and altitude hold functions.


The AFC was developed originally to interface Archangel's Air Data Attitude Heading Reference System (AHR150A) to aircraft with legacy autopilot servos/servo amps.  Archangel's AFC has 100% DO178b Level B operating software. The AFC monitors input ARINC 429 data as well as internal functions.  It has two fault outputs: ADAHRS fault and AFC fault. Data outputs of the AFC are Roll Angle, Roll Angle Error, Pitch Angle, Pitch Angle Error, Roll Rate, Yaw Rate, Heading Error, Altitude Error, True Airspeed & Lateral Acceleration.

The AFC measures 2.63" (H) by 5.73" (L) by 5.25" (W), weighs 2.2 lbs and operates from 16 to 36 VDC using less than 10 Watts maximum.
