This is a follow-up to my original post.  What is the spacing between the pneumatic ports on the ADAHRS?  I would like to close-couple 90 deg. elbows and the best I could do would be AN822 (pipe-to-flared tube) directly into the ports.  But I suspect that the spacing would allow these only in the static and AOA ports.  Maybe there's enough clearance to install a 45 deg (AN 823) fitting in the pitot port, but I can't tell from the installation drawing.  There are other, less desirable but maybe necessary alternatives.  Any suggestions greatly appreciated.

Are the dimensions on page 5-3 of the install guide not enough? That's a to scale drawing so you could grab calipers and get any other dimension you need. Let us know if you need more (I'm out of the office so I don't have an AHRS nearby I can measure this on for you)

The only other dimension I need is from the underside of the mounting plate to the centerline of the inlet ports. I've swagged it at 0.5", but suspect it's a bit more. The exact dimension would help me nail down my mounting bracket design. Thanks for the help.

.735", give or take a bit. It was measured with calipers, which was a bit awkward to do. If you need it more precise, I'll need to bounce it off our engineering team.
