Adamson) ________________________________ Message 1 _____________________________________ Time: 12:50:00 PM PST US From: "Palvary" Subject: AeroElectric-List: TruTrak ADI Dennis, Dennis, and Mike, Thanks very much for your user reports. The instrument does offer great value, but now I'm not sure it is what I want. The Tru Trak ADI has a novel way of helping the pilot hold proper attitude in IMC. Supposedly there are human factors studies indicating that it is a better way than just the traditional horizon indicator. From what I can see, though, the device is simply putting in one convenient unit the turn coordinator , vertical speed indicator and GPS track....devices I already have on my panel. I think the suggestion to fly one first hand is the way to go for me because I'm being old fashioned and believing I will miss the true attitude indicator. --Jose ________________________________ Message 2 _____________________________________ Time: 01:47:05 PM PST US From: "Peter Pengilly" Subject: RE: AeroElectric-List: TruTrak ADI Jose, I have had an ADI for a couple of years. Mine has an integral GPS, so the display shows track ' that was the original reason for getting it, as well as my T&B started to sound like a coffee grinder. When you get slow the display alternately shows =93A_S=94 (for airspeed) and the track number, to remind you to look at the ASI (the theory being the ASI gives better information at slow speed). The speed when the AS is shown can be set by the user. I think it does much more than combine the 3 instruments you mention, when you are flying normally in the cruise it allows you to keep the aircraft in control, on track, and pretty much on altitude by reference to one instrument. Clearly reference must be made to an altimeter for accurate height keeping. I installed the instrument as an IMC back-up in a VFR airplane, and I am very happy with it, it is quite intuitive to use. I have some hood time with it, but no actual. If you are wanting to replace an attitude indicator, then I would suggest you definitely should try one out first. It may suit your needs, it may not. Also, the package is square and a fair amount larger than a regular instrument (perhaps 3=BD=93 square?), with a 9 pin d-sub + pitot pressure on the back, so make sure you have sufficient space behind the panel.

The products include the AMX-2A 10-channel audio mixer, the ASX-2A high-fidelity stereo music adapter and the AL-1A tone annunciator device. All three products work seamlessly with virtually all intercoms, audio panels, radios and other aircraft audio devices. All three are packaged in D-subminiature connector shells, thus making them extremely compact and light. For more information www.vx-aviation.com =============================================== If you are familiar with Bob's isolation amplifier and tone generator, you'll see a vague family resemblance. The miniaturization is due to a large part by using more advanced integrated circuits and components specifically designed for "height challenged" packaging. The 10-channel audio mixer is a real problem solver if you are using an intercom and need to connect a bunch of audio sources. The stereo music amplifier is self-explanatory and the tone annunciator replaces those annoying sonalerts or easy to overlook lamps with a somewhat less annoying beeping tone in your headphones. One thing worth noting about these devices: There are no exotic components or embedded software used. Years from now, if they ever need to be serviced, any competent electronics tech can do it. Something to think about when you consider using gee-whiz new gizmos in you're a/c.

Adamson" Subject: AeroElectric-List: EL Lighting Ok, so the docs on the UMA EL lighting says to twist the wires on the AC wiring for 8 turns per inch... Ok, but has anyone used shielded wire? I'm wondering if there is an advantage to using a 2 conductor shielded tefzel wire (which is twisted internally) and then just ground the shield at one end. Will it be any better or worse than just twisting the 2 wires - unshielded that UMA gives you? For those that don't know, the EL lights use AC (around 100V) to cause the lights to glow, it's low current, but AC and I'd just as soon limit any source for Hmmmmmmmm... Thots?
