Dynon Pitot Probe

[James_Rekieta]

After taking the tape off the snout of the pitot/AOA probe and looking into the inlet opening, I noticed that the inner tube does not align correctly with the opening in the nose piece. Should I attempt to reach up into the opening with a small phillips screwdriver or such and try to align the tube with the opening in the snout?
Thanks,

No, that's not necessary. Remember that we're measuring PRESSURE, not flow, so the slight misalignment won't affect the performance of the Pitot.

OK, Thanks.
Without knowing the inards of the snout I was just wondering if the misalignment would allow leakage to the AOA section and thus cause problems with it's function. Will leave as is.

Does the Dynon Pitot probe AoA function allow the Dynon Pitot to be more accurate at higher Angles of Attack?

I know many aircraft suffer from inaccurate measurement at high AoA, either because the flow conditions around the pitot opening change or because they are flying so slowly that the AoA doesn't work well.

Does the Dynon Pilot design have any special benefit in terms of these issues?

The short anser is "yes" to Battson's question. Indeed, one of the design features of our AOA/Pitot probe's design does make the pitot port less sensitive to AOA changes than other designs, so the difference between IAS (what the pitot sees) and CAS (calibrated airspeed, or airspeed from pitot /static sources that are "perfect") should be better than your garden variety pitot.

On the other hand, the AOA port is designed to be extremely sensitive to changes in angle of attack.
