From: "EFII" Hi Bob and everyone else, Here is our take on the Bus Manager: We wanted a simple one box solution to provide the management necessary for a two battery setup to support electronically dependent engines. The creation of a protected "Essential Bus" being the primary goal. The Essential Bus is the protected power source for the engine electronics. We also wanted some other items such as: Battery charge isolation, ability to start the engine off of either battery (or both), and automatic management of a dual electric fuel pump module. The Bus Manager is simply the solution for the above requirement. It does not require pilot intervention to supply current from either battery to the Essential Bus. It also does not require pilot intervention to engage the backup electric fuel pump. In addition, there is a third level of redundancy via the Emergency Power switch. There is a Main Bus output powered by the primary battery to power non-flight critical systems. The Bus Manager also supports one or two alternator operation. Most two seat airplanes can use two Odyssey PC625 batteries for the system. Two of these batteries together are similar in size and weight to one Concord (RG-25) aircraft battery. The failure mode the we have seen most in small aircraft is simply a loose wire somewhere. If the loose wire happens to be a battery cable or primary bus supply wire, this can spell trouble for the engine electronics. Having multiple paths for electricity to reach critical equipment is the simple solution to this issue. An architecture that allows the backup process to occur without pilot intervention means that the engine never skips a beat if one supply source goes down - this is a big deal and provides a big comfort level. I have witnessed an entire panel go black and the Bus Manager protect the engine without power interruption. Anyhow, those are the goals of the Bus Manager. It is a simple one-box solution to a semi complicated problem. In most experimentals, the Bus Manager can provide the the power distribution for the entire plane. It really makes power system setup a simple task. And simple means reliable.

Since there is a preponderance of hardware geeks on the AeroElectric list, I thought you guys might be interested this app from a long time list member/contributor. Allow me to introduce avAltimeter Not many many people are aware that in the iPhone 6 and later, Apple has incorporated a Bosch barometer chip. I recently released to the App Store a unique app which emulates an analog flight altimeter with a number of "smart" features including a Kollsman window for setting the current pressure, calculation of Density Altitude, true airspeed and takeoff performance. The App also provides a warning for supplemental oxygen consistent with US FARs. Obviously avAltimeter is not FAA TSO approved and so I provide it for entertainment only. At present it can only be run on iPhone 6 and later, and not iPads or iPods. I understand the new Samsung Galaxy S7 now has a barometer chip as well and I plan to transfer the code to Android soon.

One suggested improvement in many parts of the world (including here in Australia) metric is needed for Celsius, but we still use Feet for altimetry (if not, literally tens of thousands of altimeters would need to be replaced), so a combination of Metric for Celsius and Imperial for Altimeter/DA in Feet would be handy when you next update the app. Cheers, Stu > On 28 Jun 2016, at 09:26, Robert Borger wrote: > > > Ira, > > Just downloaded your app. Very nice.
