Update with Pics and Vid's
« on: February 19, 2018, 08:57:36 PM »
Finally finished the electronics for the overhead panel(s).

My pit became ahead of schedule due to the introduction of new led replacement 387 bulbs. Before I had to take the (Grimes) OEM lamp holder(s) and modify it to accept 5mm LED's, then include a resistor on the respective IO board for operation.

These new lights just slip in after removing the old ones, no resistor required as well....a bit pricey though,,,, at close to 10 bucks per bulb! (I justified it by figuring out my hourly rate per lamp holder modification).

For those interested, all the Master warning captions, and overhead annunciators are 100 percent functional.

The power up sequence is identical to the real Aircraft, that is to say that only certain items are powered with battery master on only, you have to either introduce external power, or start the APU to bring the generator online to bring the aircraft up to a normal power level.

The, (real), engine gauges have performed flawlessly so far. I initially had them operate through Open Cockpit DC servo motor boards, but I found that some of the gauges would 'lag' or 'freeze' when too much data was being transferred.

This problem was solved by a CanBus setup, supplied by Bodnar Electronics. These gauges use most of the gauges original internal hardware, so they do not have to be modified to the extent of the initial gauges. 

The instructor panel station still needs to be connected, and there is still a lot of loose ends to tie up...but I think I will by picking out flight deck floor carpeting pretty soon!

Outstanding job! It looks great. It would be awesome to see a video of the startup sequence sometime! :)

I am little embarrased, but what aircraft type is that? Looks like an avro?

Sounds expensive ;D.

Yes Nick for sure. My fault...we made plans some time ago but life ( for me) got in the way. I will PM you in the next couple of weeks and maybe we can get together. Would love to see your pit as well.

@737NG....I have the VR flight MCP installed. I used to use the go flight product...but it failed on me after minimal usage.

@Atomic..sheep’ The parts were basically free...with the exception of the thrust lever quadrant of which I paid a MTC guy a couple of hundred bucks to remove.

I have over 20k hours in the real BAe146, I flew it from ‘88 to 2012..and after we parked the airframes I continued some part time work for another company working on the water bomber conversion. One of these aircraft was carved up for research and I was offered the entire nose section and whatever remained inside to begin this project.

Here are a couple of links to vid's on my YouTube channel.

The first is engine start on two of the four engines. These are the modified CanBus gauges courtesy of Leo Bodnar;

https://www.youtube.com/watch?v=wztpBlqScBE

The second link is battery master 1 and 2 selection followed by APU start and then bringing the APU generator online for normal AC/DC power distribution.

May as well keep going with a couple of additional short vids;

Here is the landing gear example'

https://www.youtube.com/watch?v=MtlVCEPrgao

The next vid is the Hydraulic panel operation. Note that the gauges are not aircraft specific as I have not been able to find  OEM parts for this module. This is why the hydraulic quantity gauges say "temp" and the pressure gauges are graduated in percent.

The 146 has two hydraulic systems denoted 'yellow' and 'green' and is controlled by this panel, which is manipulated following engine start.

Notice that the "brake accumulator low pressure" warning is illuminated. The accumulator can be filled three ways, (engine 2 engine driven pump, an ac motor pump, or a dc motor pump).

In this example I am selecting the DC motor pump to the momentary ON position which in turn will pressurize the parking brake accumulator. The pressure increase can be monitored by observing the parking brake indicator. (This gauge is not located on the overhead panel, but rather at the bottom of the Captains flight instrument panel, which is shown in the vid following dc pump operation).

Once the pressure increases to above 2500 psi, the 'BRK ACC LO PRESS" warning will extinguish.

Following engine start, (all four),  the procedure is to select engine 2 hydraulic pump ON first ensuring pressure increases to 3100 psi and the "lo press" warning extinguishes above 1500 psi increasing, then select the engine 3 pump on and look for the same results. Following this you select the AC pump on and PTU on, which remain in standby in the event one of the main engine driven pumps or engine fails.

A lot of the overhead annunciators on the 146 work on the NIPS principle, (not in position selected). In brief, when a valve is selected to open or close, the associated annunciator will flash on for a couple of seconds as the valve moves to its requested position. This is why you see ENG 2 VLV, ENG 3 VLV, PTU VLV etc etc flash on for a couple of seconds then extinguish following switch selection.

Once the annunciator extinguishes, the the valve and switch agree and no warning will persist. Should a valve be commanded open or closed and it fails to travel, in other words the valve and switch position do not agree, then the master warning system will be activated

Oh wow, that's awesome. Those rocker switches are ludicrously expensive, definitely a lucky turn of events for you :).

Some nicely thought out wiring going on there! Looks impressive.
