SkyView System Installation Guide - Dynon Avionics

Accessory Installation and ConfigurationAOA/Pitot Probe MountingDynon’s standard AOA/Pitot Probes are designed to mount under the wing. The information inthis chapter primarily applies to an under-wing installation.Dynon does additionally make a straight boom-mount AOA/Pitot for customers that haveunique mounting requirements. It is available only in an unheated version. As the boom-mountAOA/Pitot installations are usually custom/unique, no mounting brackets or mountinginstructions are provided by Dynon. The methods and materials needed to install the boommountAOA/Pitot are left to the customer to best determine.AOA/Pitot Probe Mount LocationThe Dynon Avionics AOA/Pitot probe only functions correctly when mounted in a locationwhere the airflow over the probe is relatively undisturbed by the aircraft. In general, werecommend that you mount it at least 6 inches (150 mm) below the wing and with the tip ofthe probe between 2 and 12 inches (50mm to 300 mm) behind the leading edge of the wing.Typically, pitot probes are mounted about mid-wing span wise to minimize the effects of boththe propeller and the wing tips. Testing during the probe development has shown that thestandard mounting locations for the pitot probe in the RV series of aircraft also works for theDynon probe.AOA/Pitot Probe Mounting InstructionsAfter the mounting location has been determined, mount the pitot mounting kit per theincluded instructions or fabricate your own mount. In either case, mount the probe securely tothe wing such that the body of the probe is horizontal during level flight. Drill and tap mountingholes (#6-32) on the probe to match your mounting bracket. Use caution when drilling theholes, ensuring that you avoid drilling into the pitot and AOA pressure lines. As long as you donot penetrate these lines, you may drill all the way through the outer metal without affectingthe probe’s waterproofing.15-8 SkyView System Installation Guide - Revision O
