Thanks, Roger. Just looking at the old AI seem more "right" to me than the
current ones. I wonder if there was human perception factors research done on the AI's to determine which depiction is most intuitive? JimC "Roger Halstead" wrote in message ...

It seemed more natural for me to think of how the plane was doing relative to the horizon rather than how the horizon was doing relative to the plane. It likely varies from one person to the next, but I think I would have been happy had the AI been built, as you say, "outside-in". I'm with you. For some reason I have to FORCE myself to correctly interpret the standard AI. It has *always* seemed backwards to me. Logically, I don't know why. I am "fixed" in the plane and seeing the background of the AI as a virtual "outside the window horizon" should be perfectly natural... but for me it just doesn't work well. [And yes, I fly a lot of hard IFR. G] Hey! Do I have a deal for you:-)) I have one of the outside in AIs setting on the work bench. Fully operational, but old. Looks to be in good shape. I took it out of the Debonair early on. The photos aren't the best, but they show the difference. http://www.rogerhalstead.com/gauges.htm Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair?) www.rogerhalstead.com Return address modified due to dumb virus checkers ----------------------------------------------- James M.

Surely you mean a "slight bank to the right"? If it really is a slight bank to the left, I'm not surprised that there were accidents changing to and from these gauges. I personally think that there is no "right" answer for the inside/outside perception thing, but that it's like track up/north up on maps. I find north up more intuitive, but I also find the inside-out AI more intuitive than the outside-in turn coordinator. a. |

Oops...I replaced the photos last night...bout 2:00 AM or so and neither compared the position of the indicator with the old photos, or bothered to read the text. sheesh That's what I get for staying up so late. Hmmm gotta go fix a page. Thanks for bringing that up. It was right for the previous photos, but the photos weren't real sharp.

Roger Halstead writes: The photos aren't the best, but they show the difference. http://www.rogerhalstead.com/gauges.htm At first glance it gave me the impration that it was nose down with a right bank. After looking at it for a moment I noticed my error. I'm going to attibute the error to the fact that the face of the AI is convex. |
