________________________________ Message 2 _____________________________________ Time: 06:54:10 AM PST US From: Gary Casey Subject: AeroElectric-List: Re: Z-19 and considerations of SYSTEM reliability I missed the start of this thread so pardon me if my post misses the mark. Regarding an automatic way to turn on the backup pump, as I understand it either or both Columbia and Cirrus have this feature. I put it in my Lancair, but it has a Lycoming engine in which fuel pressure does not affect fuel flow - it doesn't matter whether it has one or both pumps working. Some engines (Continental fuel injection systems) are affected by inlet fuel pressure and there have been problems with over-fueling these engines, according to what I have read. Both Cirrus and Columbia use Continental engines, so that is contradictory. My system consists of a pressure switch (normally on), a latching relay and a warning light. The manual switch has Off, Auto and On positions. I turn it to Auto to prime the engine, after which I turn it Off and then back to Auto to verify there are no fuel leaks (the pump should stay off with the mixture pulled and the engine not running). Before takeoff I verify the pump is in the Auto position. The problem is that I have the pressure switch set at the minimum operating pressure of about 11 psi the pump will occasionally turn on. Maybe I should set the switch at a pressure significantly below operating pressure. If I run a tank dry the pump will come on BEFORE the engine quits, although it doesn't prevent it from surging for a few seconds until all the air is purged. Botttom line - I think this feature is a good thing for engines that aren't affected by having the backup pump come on even though the primary pump is working well. In my mind, an "active" safety system in an airplane that has the pilot in the loop is not a good thing. Sometime unavoidable, but still not a good thing. I like the idea that the backup pump will turn on instantly when needed without me having to do it.

That is just for the one position light. On page 24 it says up ot 4amps TOTAL, which I would take to include both the colored and the white position lights. So as Bob says, using this model the Nav lights draw 4amps each side, two bulbs per side or 8amps total. Thus it depends upon which model position/strobe light you use how the wire will be sized and fused. Hope this helps Marty in Brentwood TN RV-6A wiring (man there's a lot of wire). I've got the stobes switched and 'breakered' separately with a 7A Klixon. The wingtip position/nav (A600 PG/PR) lights, which are clearly shown as 4 amps at 14V on page 24 of thier documentation, but here I see the wattage (26 and 24, respectively) for the first time, and so it does appear that is the "total power consumption" for one Lamp Assembly (forward and aft) but not the pair....

But the server is >probably the limiting factor. I think this is the case. When testing my Cox service with NetMagic's speed test utility, typical numbers are 4-6 mbps download and 581 kbps upload. Keep in mind that these are BITS per second that reflect the system's data rate. File sizes are in BYTES . . . 8-bits per byte. Roughly speaking, a system that downloads at 1 mbps will take 7-10 seconds to download a million byte string depending on formats, compression, error checking, etc. All other things being equal, I should be able to bring the 400MB file down in something like 10 minutes or so. I think I recall having that kind of access some time ago . . . but I don't recall now if my site was running off Matronics or the server I owned out in SF. It took me right at two hours to upload the file to the server last night. I would have expected a download to be about 6x faster or 20 minutes. I just did a trial access of the CD and my browser reported a 6+ hour task. I'm thinking about splitting the CD up into individual sections. A great deal of the material does not change from revision to revision . . . the published works for example. I'll put some thought into a re-organization of the information offered such that it's still accessible but subject to less repetitive downloading effort.

For just one radio, the "avionics master" switch was a waste of time and reduction in reliability. In fact, if you're only going to install a few radios total, I'll suggest you ditch the AMS and just turn the radios on/off as part of your checklist ritual.

Another good option would be BitTorrent, or another peer to peer service. With BitTorrent, computers that have downloaded all, or part of the file, are used as upload servers. The available bandwidth goes up very quickly once the file has spread to several computers. http://en.wikipedia.org/wiki/BitTorrent -- Kevin Horton Ottawa, Canada ________________________________ Message 18 ____________________________________ Time: 01:35:35 PM PST US From: "Robert L.

So I'm wondering how much of a bottleneck Bob's host website was vs. local comcast by comparing what others might be seeing. Looking forward to do some number comparisons. thx, luck ======

After 9 hours, my transfer rate has fallen to 7.76KB/Sec and it says I still have 4hr 42mins left ;-)

Speaking of slow, anyone care to share what their average transfer rate/total time was?

I have this "upgraded" comcast high speed service (was upgraded last week) and if anything things seem slower. I was averaging 12.0KB to 16.0KB per second throughout the day. Estimated times remaining were bouncing back and forth between 8.5 to 7.2 hours for the first hour or two. An hour later and I've barely transferred over 10% of the toal 393 MB.

Pretty lame for a local comcast system that claimes 8MB per second on downloads. So I'm wondering how much of a bottleneck Bob's host website was vs. local comcast by comparing what others might be seeing.

Looking forward to do some number comparisons.

thx,

luck

Nuckolls, III" Subject: AeroElectric-List: CD REV 11.1 A note from Matt Dralle: Now, if there are two people trying to download it at the same time, the total download time will double for each person or 1 hour 10 minutes. If there are three people, it will triple, etc. I next took a look at the web logs for this file and found that there are a ton of people in the last couple of days trying to download the file. If you look at the time stamps, many of these are occurring at the same time. That's just a lot of data for a lot of people to pull off the server at one time. It also looks like a lot of people are thinking something is wrong, so after a while, then stop the transfer and start it again, which just causes further delays as a whole." He tacked a copy of the download logs and there was a general overload of the server. Sometimes there were as many as 6 or 7 folks trying at the same time which DOES slow things down a lot. I'll suggest that folks still looking at long downloads stop terminate the activity and then wait a week or so. The server is simply swamped right now. If our benevolent brother -Dj is able to support this activity with wider bandwidth, perhaps we'll have an alternate repository that facilitates better service.
