Dynon Avionics Pitot/Static Test White Paper

[vlittle]

I've read the white paper that describes the work-around for the pitot-static testing bug.

In Canada, we need to have a static system and transponder certification every two years.  This means that a certified avionics shop does the testing.  I've had this performed several times.

It is unlikely that the avionics shops are familiar with this white paper.  Does this mean that my EFIS dynamic calibration is no longer trustworthy?

I strongly suggest that you introduce a 'calibration' mode that will allow service techs to properly test the EFIS without the constant power-up/power-down sequences.  All they need to see is altitude and airspeed during this calibration mode.

Also, how do we establish new dynamic calibration after a standard pitot/static check (ii.e. not using the bug work around)?

We'll have an answer for you after Oshkosh.

Not doing this procedure "correctly" won't affect most units most of the time. Our ADAHRS has a dynamic calibration routine that, after performing a pitot/static test without taking the steps outlined in the white paper, can get into a state where it doesn't properly adjust from that point forward. If you're seeing a persistant non-zero turn rate (and possibly a slightly incorrect attitude indication in flight), your unit has managed to get into this state. But if turn rate is null on the ground and when straight and level, you're fine.

It's in our Product Documentation section, under the section titled Technical Addendums and White Papers, and the document is titled Pitot Static Test Procedures (links are inline).
