AOA

I'd like to post a picture of the AOA indicator in our RV6 to accompany comments about same, but am restricted from doing so. Might I request clearance through that airspace?

The file is probably just too large. Try hosting elsewhere and posting a link.

It's the posting rule that says "you may not post attachments" that's hoolding me up.

VAF does not host pics.

You got to host em somewhere else and then link to em in your post.

There is a FAQ in how to do this on the left side of the screen.

Thanks, Brantel, I'll give it a whirl.

As mentioned in my initial post, I'm part owner with 2 other pilots of an RV6, none of us having had anything to do with building it - but we sure enjoy flying it! It has an AOA indicator, as depicted in the attached pix,

, for which we have no documentation or installation information. The back of the case reveals only that it was made by Dwyer Instruments, Inc, of Michigan City, IN, with one port labelled LO and the other HI. The Dwyer support technician I spoke to was forthcoming with zero helpful information and actually seemed distressed that one of their instruments was installed in an airplane. We'd like to fine tune the calibration - is anyone familiar with this particular instrument and where it may have come from?

In 39+ years of flying a variety of light aircraft, this is my first experience with an AOA indicator, and I wonder why it isn't more commonly used (I read and enjoyed the discussions on this forum). Having a depiction of lift compensated for weight and speed, available at a glance, is a reassuring addition to the feel of the aircraft at slow approach speeds.

I'd recommend just uploading it to http://imgur.com/. It is super simple, not covered with ads and a very friendly place to post pics.

Why do you 'spect that red X is in the text instead of the link to photobucket for the pix? I must be missing something simple...

Hey Mike, I am not a real code-slinger, but I took a look at your post, and see that you are pointing to a directory, but not a file. You have this between the "IMG" brackets:

You need the complete link to a particular file to make it work.

Noticed the mention of Dwyer.

I know of two AOA installations with that differential pressure instrument.
The commercial one is here:

Sam Buchanan documents his LRI install here:

There is a homebuilt version that I can't seem to find this morning. Works the same way and uses a Dwyer Magnahelic gage.

Try looking at this.
