MIP: Part list for EFIS

There is a simple way of making fully functional EFIS panel without using sophisticated encoder embedded into rotary switch and push button. I will be using only standard encoder with button and will have to do some extra programming. As far as I understood Opencockpit's manual for EFIS they use the same architecture. Part list:

• EFIS panel + 9 push buttons
• 9 * tact switche (12x12)
• 2 * two-position ON-OFF-ON switche 
• 4 * encoder with built-in push button
• 10 * bright white led (panel backlit)

EFIS will be connected to FSBUS DIO card, the same running MIP switches. I will also publish the software and configuration in Prosim737 suite.

FMC: FSBUS for FMC (second card in the cockpit)

Soldering was the first step to assembly FMC panel. There are a few real photos below. Unexpectedly, it started without any issues; great success :-).

If you need more details on architecture, connections and programming select the GENERAL\Electronics section from the menu.

FMC: The idea and part list

Basically, the heart of each FMC is the software and the panel itself is relatively easy to assembly. Here you have the list of needed parts.

• "dummy" FMC panel with 72 push buttons (from Poldragonet) / 110 EUR
• 5.6" LCD screen (VGA input, resolution 640x480) / 69 USD
• FSBUS electronics / approx 20 EUR
• 72 tact switches
• 3/5 leds
• 10 white leds (high-brightness) to back-lit the keyboard 

A long time ago I purchased dummy FMC from Poldragonet and the plan was to use it on FO side. But now, I have changed my mind and will try to make it fully functional. All buttons will need to be unglued... 

    

The LCD 5.6" screen was ordered via Alieexpress, click here to see the item page. I was positively surprised that there were no shipment nor custom/tax costs and it arrived in 14 days from Hongkong. I read that some people were using LCD screen from PSOne console; forget about it, there is no VGA input and display quality is low.

My FMC will operate on FSBUS electronics. However, single DIO card supports only 64 inputs and remaining keys will be connected to my second card driving MIP switches and EFIS. It's not optimal solution, but I purchased all elements to assembly second DIO card some time ago. It also requires minimum 3 outputs for EXEC (green), FAIL (red), MSG (amber) led annunciators, but my panel will also support OFST and DSPY.

MIP: Preparations for EFIS

As of now there has been only some preparations done to make EFIS module, see the below picture. It's due to the fact that I was not quite sure whether to buy MCP along with EFIS or not.

Finally, MCP was ordered from OpenCockpits without EFIS module. And, I took a decision that EFIS engraved panel which intend to be dummy panel on FO side would become functional module. The plan is to complete the work by the end of April 2013 and then connect to FSBUS IO card.

MIP: MCP V3 from OpenCockpits

Instead of making the MCP panel on my own I have decided to place an order with OpenCockpits. That was mainly due to high volume of encoders, switches and 7-segment led displays required. Of course, the FSBUS project offers full support for all parts listed above, but I had not time for soldering  :).

In general, there are two different layouts of MCP panels, it's Collins and Honeywell. As you could see below Collins one seems to look more modern, but in real aircraft functionality of both is similar. However, if you wish to obtain  plug'n play unit please look into details as usually not all switches are supported.

    HONEYWELL

    COLLINS (newest)

    (two above screens are taken from ProSim737)

I reviewed a few MCPs available on the market and some have been rejected cause of the price above 1,000 EUR. As I said my choice was V3 from OpenCockpits with white digits, no metallic box (real picture below). Well, I am happy with the quality and I strongly recommend their V3 it's fully functional, easy to configure with ProSim737 via SIOC and relatively cheap, 393 EUR incl. VAT. Real photos below...

MIP: Sixpack recall annunciators and Master\Fire buttons

It took me around 5h excluding painting time to get two-side 6pack announciators ready for use. Well, it's really cheap, but fully functional solution. Total cost was around 20 EUR for both, excluding electronics as  panels are connected to two FSBUS cards (IO/DO64) which drives MIP switches and announciators.

Before

After

Base (MDF 12mm)
You can copy the idea and adjust the dimensions to the rest of your own glareshield. I recommend to create cardboard template before cutting MDF. Note, it's better to paint after gluing.

Required parts (both sides):

• 16 5mm high-brightness led (14 * yellow, 2 * red) 
• 4 momentary back-lit push buttons (see below)
• 4 tact switches
• 2 engraved back-lit panels 60x30 (own design, click here to download .cdr file)
• 2 5mm transparent plexiglass plates 60x30
• 2 plexiglass plates 80x40

Wiring

RESET_A and RESET_B switches are creating parallel circuit. You can only use one switch, however my six pack engraved front panel is glued on it's left and right side to those switches. So, no matter where you press the front panel one of the switches will click. See the below.

I have been searching Internet for solution which could be used for Master Caution and Fire Warn. Finally I found perfect buttons 32x32mm at NOWY Elektronik. It was just only for 1,5 EUR per one. All you may need to do is to print out labels and place behind color cover. Also, you will have to replace standard bulb which is included by high-brightness led.
