To begin with, I'll post a couple of questions right now, and leave the others for later. This unit has a Failsafe Warn audio feature which allows the pilot to hear an alarm even when the unit has gone west or it is Off (at least that's what I understand it does). The GMA350 has 4 alert audio inputs (each one with Hi and Lo pins), to connect alert sources like altitude, terrain, AOA and such, and it has a FAILSAFE WARN AUDIO IN Hi (to be connected to pin 29 of connector J3502). The manual says that this "FAILSAFE WARN AUDIO IN Hi is heard during normal operation as a fifth alert input". First question: it seems that I should connect to this pin what I consider the most important alert to be heard by the pilot, do you agree? Then the manual has a "Caution" advise: "During failsafe mode both FAILSAFE WARN AUDIO IN Hi and COM1 AUDIO INPUT are connected to the PILOT HEADSET LEFT OUTPUT. During this time the output of the COM1 radio and the output of the device connected to FAILSAFE WARN AUDIO IN HI will become shorted together, potentially causing damage or interference. If the FAILSAFE WARN AUDIO IN HI is used, it may be necessary to install summing resistors in series between these sources and the inputs to the audio panel to protect the outputs from damage." Question is: where do I install these resistors, how many, and which resistance and power labels? Thanks in advance for your help Carlos ________________________________ Message 3 _____________________________________ Time: 08:48:23 AM PST US From: Janet Amtmann Subject: AeroElectric-List: Aviation related: non electric This is aviation related but not strictly Aeroelectric.

A common workaround is to subscribe to a VPN (virtual private network) that's in the region/country of interest. Then the desired site sees you as being in the same country as the VPN. This is somewhat cumbersome to set up, though. An easier solution might be to get your friend to capture the video and email it to you. Or, it might even be available on youtube or other video site here in this country. It's not uncommon for a program to have its view ability limited by which 'channel' you're viewing it on. ex: BBC programming often can't be viewed on the British BBC website from here in the USA, but you can see the same programming on BBC USA. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ________________________________ Message 6 _____________________________________ Time: 10:15:04 AM PST US From: Bill Subject: Re: AeroElectric-List: Aviation related: non electric Jurgen, Go to the "youtube" web page and enter "Horton brothers flying wing" in the search window.

Something I've observed about Sharpie and/or magic marker inks. I have been using the 6qt 'shoeboxes' by Stearlite as dust tight materials storage in my shops for several years. I label the ends of the boxes with yellow vinyl tape captioned with a Sharpie. The label on the right is about 10 years old. The drop in letter density compared to the label on the left is observable. Emacs! The exposed lettering appears to literally evaporate. Evaporation rate is probably temperature and air flow dependent. There might also be effects of ozone and/or hydrocarbons in the surrounding air. I've developed another technique for crafting these labels. After captioning with the marker, I put a layer of clear tape over the lettering. . I'm thinking that the clear overlay will have a profound effect on the robustness of my shop labels. For wire labels laid on white heat shrink, one might consider putting a layer of clear shrink over the label. I note too that Sharpies come in a 'permanent' version which is also available in ultra-fine points. http://tinyurl.com/y8rj6t3j One of these days I'll conduct some experiments with this marking methodology and I'll hang some samples under the hoods of my vehicles.

Non-Cranking (Small) Aux Battery and Bus You sure did come to the right place for peer reviews and critical thinking. If you post I will be more than happy to review..but I am not very talented in this area and normally do not comment unless none of the many more qualified voices speak up. I do not have electronic ignition and thus do not have to worry about my lawn mower engine (IO-540) stopping if I screwed up my electrical system. I did use Z13-8 and followed it closely knowing that it is tried and tested. I have lost two alternators in my 700 hours in the airplane, one at night, and did not have any worries. I designed and built for mission =93 long cross country. Rene' 801-721-6080 From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of Charles Rogers Sent: Thursday, August 31, 2017 3:41 PM Subject: AeroElectric-List: Aeroelectric Figure Z-35. Non-Cranking (Small) Aux Battery and Bus Greetings, My name is Charlie and this is my first Matronics post. I have a RV-8 with IO-360. It has a simple electrical system with one alternator and one PC-680 Battery on the firewall. My mission is daytime VFR. I am preparing to install dual electronic ignitions (Simple Digital Systems - CPI). In consideration of an alternator failure, I want each EI circuit to be independent of the other. To achieve this, I am going to add a non-cranking (small) 7 AH AGM auxiliary battery to operate one ignition. The other ignition will operate off the main battery. In reference to Z-35, I have a few questions please. 1. Why are the wires marked with an * required to be (quote) "As short as practical. 6-inches long is ideal, 12-inches long max"? 2. In reference to the 12 AWG wire that runs from the battery contractor to the S704-1 AUX Battery Relay. What are the positives and/or negatives of placing a Schottky diode in that circuit between main battery contractor and the S704-1 AUX Battery Relay. 3. Is there a preference for which battery, Main vs Aux, powers the S704-1 AUX Battery Relay? 4. If I included a copy of my proposed wiring diagram could I get a peer review of it? Thank you, Charlie ________________________________ Message 15 ____________________________________ Time: 06:41:48 PM PST US Subject: AeroElectric-List: Re: Aeroelectric Figure Z-35. Non-Cranking (Small) Aux Battery From: "user9253" 1. The * wires are not protected by fuses. The shorter they are, the less chance of them getting in trouble. 2. The main advantage of a diode is that it prevents aux battery current from flowing to unwanted locations. The disadvantage is that the aux battery will be charged at a lower voltage. But that might not be a problem since the aux battery will seldom be discharged. 3. I would energize each relay or contactor by its own respective battery. How would the aux relay be energized if the aircraft electrical system and main battery are dead? 4. It seems that Bob is reluctant to comment on proposed wiring architecture. Many have tried to improve upon his proven designs but few succeed. It will not hurt to post your wiring diagram. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=472411#472411 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
