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.
