1. INTRODUCTION

Thank you for your purchase of the AOA/Pitot Probe (Dynon Avionics P/N 100141-000) or the Heated AOA/Pitot Probe (Dynon Avionics P/N 100667-000). This guide provides some background on the concept of angle of attack and explains the steps to install both units in your aircraft.

This manual does not address installation of the Dynon Avionics AOA/Pitot Boom Probe, P/N 100532-000.

The two probes are compatible with the following Dynon Avionics products:

 EFIS-D6  EFIS-D60  EFIS-D10A  EFIS-D100  FlightDEK-D180  SkyView system

(Hereafter, the EFIS-x and FlightDEK-D180 are referred to as “EFIS unit”.)

After physical installation is complete, the AOA/Pitot Probe must be calibrated for your airplane and your system. Instructions for AOA/Pitot Probe calibration are contained in the Installation manual for each compatible Dynon Avionics system. Installation manuals for these products can be found at: http://docs.dynonavionics.com.

The pitot function of the Dynon AOA pitot probe measures pitot pressure. This allows it to work with any standard airspeed indicator. However, the AOA functionality is designed specifically to work with Dynon Avionics and Advanced Flight Systems products. Do not expect a Dynon Avionics AOA/Pitot Probe or Heated AOA/Pitot Probe to work properly with any AOA system other than those of Dynon Avionics or Advanced Flight Systems.

AOA/Pitot Probe and Heated AOA/Pitot Probe Installation Guide Rev. C 1-1

Introduction

To display angle of attack on a Dynon Avionics EFIS unit or SkyView System, only a Dynon Avionics AOA/Pitot Probe or Heated AOA/Pitot Probe is supported. Using

another manufacturer’s or homemade AOA/Pitot probe may not produce accurate AOA information.

To ensure accuracy, it is very important that you install the probe correctly and perform the specified calibration steps. We recommend that you read and understand this entire manual and the corresponding calibration procedure in your EFIS unit’s Installation Manual or SkyView System Installation Guide before proceeding with installation.

The exterior of Dynon Avionics’ AOA/Pitot Probes and Heated AOA/Pitot Probes exterior are plated. Do not polish the probe – doing so could abrade the finish.
