Dynon AOA Probe installation questions

[hhobbit]

Hi all,

I have a D180, and am considering installing the AOA probe from Dynon.

Can anyone say if it is difficult to instal, did the extra nylon air line go through the wing and pillar easily, and did the wing have to be slid out or removed, stuff like that.

Finally does there exist any LOA from the factory for this equipment?

your description of that inner metal sleeve inside the wing is of concern, it sounds a no-no for anyone without a specially made drilling jig. If such a tool was available for hire from FD then the job would be straightforward enough probably. But there is the question of threading an extra air line which in fact should be ascertained before widening the wing opening.

I would not go ahead without a factory LOA on this one!

Now if Dynon had a probe that was the same diameter as the present one, then it would be simple enough.

Do you have the pitot tube that is the size of a pencil, or the one the size of broom handle?

Not aware of anything larger, so I would say the pencil one. BTW am writing to FD for advice. One desirable solution might be an adaptor to pass two pressure lines past the narrow hole in the wing. There can't be all that much to fabricating a secondary pitot head, but it would require a bit of cut and try to see if there was a reasonably smooth pressure curve for increasing angle of attack.

It appears it is possible to run a second line down the pillar, but I still need to hear that unambiguously from FD.
