SkyView for Twin Engine AirCam

[Rubi_Halberthal]

What is the status of software development for the Lockwood AirCam (being twin engine?)

 

[dynonsupport]

We're working with the folks at Lockwood on it, but I'd probably have you bug them about it since they need to do some testing and then possibly iterate with us on it.

 

[Rubi_Halberthal]

Thanks for your reply. I am working with the folks at Lockwood - I just purchased the D1000 through them, and I am willing to be the test-bed for you, using the SkyView D1000 in my AirCam. I am in contact with George Webber at Lockwood. Please let me know which other items I need to add to my purchase, so that the twin engine version could be tested by me. I am interested to get from you a technical focal point so that I will be able to communicate direct. My e-mail is: rubi@haldor-tech.com. Thanks - Rubi

I am building an AirCam too and I am interested in this set-up. I look forward to seeing how this goes. You may see progress on my structure at Aircambuilder.blogspot.com

I am also building an Air Cam and am planning to go with the Skyview D1000 if dual engine monitoring is possible.

John:

As of this moment (late December, 2011, firmware v3.2.2) dual engine monitoring / dual SV-EMS-220s connected, is not supported in SkyView.

Having multiple SV-EMS-220s (for supporting complex engines needing more inputs than one SV-EMS-220 can provide) and using multiple SV-EMS-220s for monitoring dual engines are both features that have been requested and will be considered for implementation in the future. But, at the moment, those features aren't imminent.

Dynon - I dont really understand your response to John. It was my understanding that you have a version ready for AirCam, and that you just need a test bed to run the system for final approval (that is what I understood from Lockwood people, and based on that I purchased through them the D1000). If this development for the AirCam is not imminent, and the firmware will be different, than - should I cancel the purchase at this point, or you can commit to developing this capability ASAP? I have designed the avionics of my AirCam (under construction) around the D1000. What should I do now?

Rubi, Bill, and John:

Apologies - the current forum tender was not previously up to speed about the AirCam situation.

Bottom line - yes, SkyView will likely work for the AirCam, but it has yet to be verified in testing. Dynon and Lockwood have developed a SkyView configuration that allows both engines on an AirCam to be monitored with the inputs available on a single SV-EMS-220.

So, if you want to help make this happen, work directly with Lockwood to help with the testing that's needed to verify Lockwood's SkyView "AirCam configuration".

Minimum for what you would need from Dynon to help test the "AirCam Configuration" is a SkyView SV-D700 or SV-D1000 display and an SV-EMS-220. I'll speculate (but don't KNOW) that you'll also need an SV-ADAHRS-200 plus SV-GPS-250 for flight data that might affect engine performance / monitoring, such as altitude, airspeed, OAT, etc. (Again, this is MINIMUM equipment - likely you want a fully-featured SkyView system).

Apparently the "AirCam Configuration" will use a custom Engine Sensor harness and selection of engine sensors, but Lockwood will have to advise you about that.

Here's some background on the information previously provided about not currently supporting dual engines / dual SV-EMS-220s. NORMALLY, to monitor twin engines, you would need one SV-EMS-220 per engine (LOTS of sensors to monitor on an engine). We've had requests for supporting dual SV-EMS-220s, but we haven't done any work towards that yet. But Lockwood and Dynon worked things out to be able to monitor BOTH AirCam engines on ONE SV-EMS-220.

Dynon, does that mean that my (2) 4-cylinder engines in the Defiant can be monitored?

 

[jakej]

mee too... I have a customer (Defiant builder/owner) who would be interested in knowing the answer.

Rubi and JakeJ:

Generically, a single SV-EMS-220 Module has the following inputs:
* 1 each AMPS Shunt
* 2 each Fuel Flow
* 13 each General Purpose (resistive, active voltage sensors - see details in SkyView System Installation Manual)
* 1 each Manifold Pressure
* 2 each RPM
* 14 each Temperature - can be either Type J (CHT) or Type K (EGT) thermocouples
* 2 each Voltmeter

and outputs:
* 1 each 5V output (low-amperage - suitable for sensors only; can be shared amongst multiple sensors)
* 1 each 12V output (low-amperage - suitable for sensors only; can be shared amongst multiple sensors)
* 1 each Warning Indicator

Each of the inputs has a variety of widgets that can be displayed, the screen layout of the widgets can be customized, and the names of each sensor on the screen customized.

So, if you can work out a combination of sensors within the available sensor inputs on a single SV-EMS-220 that allows you to effectively monitor both four-cylinder engines on your Defiant, then you CAN use SkyView.

Ok ... great. The SV will be good for a carbureted Lyc with fixed pitch prop as no need for 2 x MAP gauges, the engine monitor may be a bit 'camped' for space - any chance of showing a mock up of twin engine display ??

As another Defiant flyer, I agree with Harry. We'd really like to use our Dynons for monitoring the engines. The correct solution is for Dynon to allow two (2) SV-EMS-220s to communicate with the system. This shouldn't be too hard and of course your competition has been doing it for years and those fliers keep rubbing our noses in this serious Dynon deficiency.

 

[Rubi_Halberthal]

Dynon - Could you provide the topology of the system components for the SkyView for AirCam? I understand that a single SV-EMS-220 is required, also SV-ADAHRS-200 plus SV-GPS-250, and a SV-BAT-320 battery. Am I missing something? Also, I am installing an EFIS-D10A in front of the back-seat, so will I need SV-NET-10CP network cables? Will this work between the D1000 and the D10A?

 

[dynonsupport]

You only need one EMS module is needed is the key thing that people might be wondering about that. Beyond that, the system can be configured however you'd like - one or two displays, one or two ADAHRS, autopilot, transponder, or not. There's no "standard" configuration per se, though maybe Lockwood will advocate one.

The EFIS-D10A and SkyView do not connect together in anyway other than you'll be T-ing off the pitot and static lines and sending them to both. You can consider the installation of both of those systems virtually independent. Actually, I take that back - the one thing you can use from SkyView now is NMEA serial output to feed the EFIS-D10A to power its HSI and other GPS-enabled features like winds aloft.

 

[Rubi_Halberthal]

Dynon - any news on the progress of SkyView for AirCam? Last update known to me is that you are working with Lockwood to test the system on one of their AirCam. Could you update?

 

[dynonsupport]

They have some test equipment in hand, but they just got it from us at the Sebring expo. So I suspect it'll be a bit longer before they have it fully tested and up and running. You may want to ask them about their progress too.

I am also building an AirCam and this twin engine monitoring system sounds very interesting. I will call George Weber at Lockwood this week to pursue this. Thank you!
