Tools and Materials Required

Dynon Avionics AOA/Pitot probe or Dynon Avionics Heated AOA/Pitot Probe.

AN5812 type mast for under-wing mounting

Appropriate fasteners

Adapters as required connect with the 3/16” aluminum tubing from the Probe to the
plumbing lines are installed in the airplane

o AN919-2D for 3/16” to 1/4"
o AN819-4D sleeve and AN818-4D nut
o AN819-3D sleeve and AN818-3D nut

Two plumbing lines (usually ¼” soft aluminum or plastic tubing) routed from the AOA/Pitot
Probe to the EFIS unit or the SkyView system’s SV-ADAHRS-200/201

Appropriate drill and tap

Mounting

The Dynon Avionics AOA/Pitot Probe (P/N 100141-000) and Dynon Avionics Heated AOA/Pitot
Probe (P/N 100667-000) are designed to be suspended vertically on the underside of a wing;
the beveled face should be at the 6:00 position.

There is no provision in these products for horizontal mounting; the tip of the
Probe is permanently installed and cannot be rotated.

See the TOOLS AND MATERIALS REQUIRED section above to obtain a suitable “pitot mount” for
the Dynon Avionics AOA/Pitot Probe or Dynon Avionics Heated AOA/Pitot Probe; Dynon
Avionics does not sell this part.

MOUNTING LOCATION

The Dynon Avionics AOA/Pitot Probe / Heated AOA/Pitot Probe will work correctly only when
mounted in a location where the airflow over the probe is relatively undisturbed by the aircraft.
In general, we recommend you mount it at least 6 inches (150mm) below the wing and with the
tip of the probe between 2 inches (50mm) and 12 inches (300mm) behind the leading edge of
the wing. Typically a pitot probe is mounted about mid-wingspan to minimize the effects of
both the propeller and the wing tips. Testing during the development of the Dynon Avionics
AOA/Pitot Probe / Heated AOA/Pitot Probe confirmed that the standard mounting locations for
the pitot probe in the Van’s Aircraft RV series of aircraft work well for a Dynon Avionics
AOA/Pitot Probe / Heated AOA/Pitot Probe.
