Static Port Design flaw

Postby Daneshgari » Fri Sep 07, 2018 9:06 am

Hello All:

Has anyone's else experienced air speed indication variation by 10-20 KN in strong rain? In my not even one year old DA42VI I have to open the alternate static port in the cabine to avoid such fluctuations. I have checked with Diamond factory and they say that it is normal since the tubes and so very small and any water intrusion will cause blockage of the Static Port. Thoughts or solutions out there?

Thanks Perry

Fortunately I never noticed this on my DA42-VI; maybe I just didn't fly in hard enough rain.

The DA62 has dual *heated* static ports on each side of the fuselage that the FAA required for FIKI de-ice certification, so I don't expect this to happen on my DA62.

We regularly fly in Monsoon rain and never have defect related to airspeed fluctuations reported.

I would suggest getting your mechanic to check the pitot/static system and any water drain valves to ensure there are no issues.

Thank you Kari. That is my plan when it goes for its annual this December.
