Dynon Skyview Additions Mods

[Yetti]

Still have to finish hooking up all the items for the engine Monitor System of the Sky View but here are some things I am going to discuss with my IA.

1.  Trim and Flap position.    Since the indicators are mechanical would require the installation of 2 slide resistors.   This is a preconfigured item in the Dynon screens and software.    A quick logic loop with gear indicator to make sure trim is set properly before takeoff roll.

2.  CO sensor.   Apparently they are $8.00   https://www.sparkfun.com/products/9403

3. put a thermocouple in the cabin to get inside air temp.   Have one why not.

4. Lidar sensor in the front wheel well.   Should be able to measure landings.

I'm curious - what is the Lidar sensing apropos the landings?

The ground.   Could have it announce 100 feet, 50 feet, 10 feet just like a big airplane.

Many mooney’s got the ground altitude sensors with a yellow light to display on the BK HSI(?)

It gave a bit of a hint about how high you are on an approach in IMC... 200’ agl(?)

Now GPS seems to do this more...

A lidar sensor and its cadence can make interesting soft landing opportunities...

Some people just take a look out the side window for this... 

Some people may benefit by having the 50ft reminder to look out the side window... 

Hopefully many of these small sensors can get fitted in a logical area in the belly for easy access and installation... 

if you go with the IAT, Rob has a method of motorizing the temp control... set the temp and forget it...

Best regards,

Apparently the slide resistors are pretty inexpensive.    Thinking about installing a "fun meter"   User adjustable.  You know you want one.

This LIDAR based solution for ground proximity call-outs already exists for experimentals:

Nothing to do with the skyview. Just install it, connect it to the power supply and the audio panel, configure it and you are done.

The Garmin Lidar sensor that unit uses is the same I am thinking of using.  and I have a Skyview with limited panel real estate so why not integrate it into a screen and have the skyview voice tell me about it?

I thought that light was to announce arrival at the DH when used in conjunction with the BK radar altimeter.

I imagine that is what it did... calibrated for one distance, with an echo off a standard surface...

Seems to have fallen out of favor for some other technology... probably WAAS GPS.
 

My HSI has the light, just not connected to anything...

 @Yetti wondering if you had luck installing flap position/trim indicator?
Would appreciate if you could share your experience and which resistor you end up using.

FYI, the MicroKit Landing Height System is a LIDAR system that calls out AGL.

The C version, then unit connects to the gear switch and at 200 AGL, if the gear switch is not down, it announces Check Gear.

I hooked up the flap and trim sensors using a 10K ohm slider for audio board.   https://www.amazon.com/gp/product/B07R3295X3/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

This makes it kind of work.   The problem is there is not enough voltage drop between up and down of the flaps and trim.     The only place I could figure to do this was on the trimwheel under the plane and back at the flap actuator.   So you have to run wire.

I bought the "certified" ones off Aircraft Spruce, but the travel on them was not long enough    The travel needs to be a little greater than the manual position indicators.

I believe I could just add a resistor to the circuit to get a greater voltage drop, just have not tried it.

In other news I found the way to edit the fuel tank level sensors and using the stock Mooney sensors the fuel levels are very accurate.   But I still stick the tanks.

Dynon are apparently now offering a 12" Skyview screen. Hope they give the option to adjust font sizes on that. Would be great to not have to use reading glasses.

12" was announced for experimental. Hopefully someday it reaches the certified market.

I'm still hoping that the autopilot is approved for Vintage Mooneys. I'll take one, with whatever size SkyView will fit my panel!

Dammit Dynon! Why didn’t you tell me about these new updates while I was in your booth. 
 

Yes, this is talking about the exp side but you can be sure it will added to the cert as well eventually.
