My plan was to mount it close to where Van shows it in the plans, but the simple tube version goes into the spar flange and the Gretz has a post mount. Help or better yet a picture of an operation unit would be greatly appreciated. Carl ________________________________ Message 3 _____________________________________ Time: 08:00:59 AM PST US From: "Tim Bryan" Subject: RE: RV-List: Heated Pitot Carl, I don't think I have any pictures already but I installed that same pitot and it is right where the stock position is for an RV-6. I suspect it is just slightly back in order to allow the mounting bracket for the post to go. You can go back all you need because the pitot end will actually be forward of the stock tube anyway. Just move it back enough to mount the bracket as needed. I am flying and my airspeed is as expected.

Carl I followed the instructions that came with the Gretz pitot tube mount, except I moved it one bay outboard. http://www.kilohotel.com/rv8/article.php?story 021026180308727 You have to work really, really hard if you want to screw up a pitot source. The laws of physics work in our favour, unlike the situation with static sources. A pitot source will be accurate as long as the pitot tube is far enough away from the skin to be clear of the boundary layer, it is not in the prop wash, not in the wake of something else, it is pointed roughly into the local airflow, and there are no leaks. Wind tunnel data shows that a pitot source will be quite accurate as long as it is aligned within about 15 degrees of the direction of the local airflow. Leaks close to the entrance of the pitot tube are much less critical than leaks further down stream, as any air that leaks out is replaced by air that comes in the pitot tube. The error from a leak is due to the pressure loss required to push the leaking air from the tube entrance to the leak location. Thus small leaks very close to the pitot tube entrance have neglible effect on the accuracy, which is why it is OK to have very small drain holes in pitot tubes.
