Tiller Maintenance – again

A couple months ago I had to change the potentiometer of the tiller, because is was defect. After a couple of flights I noticed that the steering drags to the left and does not center. So the first impression was that the potentiometer or the input card has an issue. But after some hours of trying to fix it, it got clear that it is a full mechanical issue.

I removed the Tiller handle and during that process the locker mechanism got destroyed… So I had to replace it with a 4mm screw (left).

And on the other side the locking mechanism was not strong enough to hold on to the potentiometer shaft. I removed the screw, drilled a hole in the shaft and reattached the screw, which is now holding the shaft tight.

After some stationary tests I have reassembled it. Now it works perfect and is finally fixed.

ProSim Display Configuration

During the years of using ProSim I always had running the Prosim Displays with 2 instances. One for the Captains PFD and ND and a second one for the First Officers PFD and ND.

After some chat with a ProSim Developer (Alex) who is responsible for the D2D integration and much more, he pointed out to me that it is better that each display is running its independent instance. Therefore the PFD will not slow down if the ND shows too much data and struggles.

So I took the time to reconfigure my setup, at least for the PFD and ND on both sides. Each display is now running a own ProSimDiplay.exe instance.

And indeed it feels smoother.

Wet Compass upgrade

During the last year’s I have used this wet Compass solution.

Now I found the post of René on the Prosim forum explaining how he is interfacing his own built wet Compass. Quite simple to be honest. Take an Arduino board (eg. this one on Amazon) and his own built compass, it’s nearly plug and play.

The Arduino board is converted to a mobiflight board with the firmware modification. Required software can be found here.

I have mounted the wet compass in its position and as there are also LEDs included I connected them to the responsible switch. Quite nice product.

Thanks René. Get with him in touch trough the Prosim Forum to get an price with shipping to your country.

Shipping was absolutely fine and René is very fast in responding and providing the asked information. I can recommend this product if you are looking for a wet Compass solution.

GSX menue on lower EICAS

A long time I have searched how to move the gsx menue away from the curved projection screen for convenience. Now I found a solution hinted in the Prosim forum. A simple lua script from Pete Dowson is the solution. This lua script generates all kind of stuff on another machine via WideFS. You can select between Weather updates, all text, all menus etc. So I tried it and this is the result.

Via the FMC and ProsimUtils you can control the GSX menue and now the menue is displayed as an overlay on the lower EICAS.

The only drawback is the you have to start WideFS on this machine as the last software to allow the overlay. This needed some adoption of my startup routine on this machine. But finally the captain and the first officer can see and interact with the menue. Sadly it’s not touchable, as my lower EICAS is a touchscreen.

Hardware issue on PFD machine

After a 2 month brake I started all the PCs for a system check and update sequence today. After half an hour the PFD pc went dark. I rebooted the machine and as soon as the windows logo appears it shuts down again. I thought of an HDD first, but it happened on different times. My next guess was one of the USB connected devices. So I unplugged all 8 devices and rebooted, same effect. I took the HDD drive out and installed it on a same spare machine, there all was working. So I decided to switch the machines. During unplugging the graphic card I noticed that the CPU cooler was not fully in place.

So this was my issue as well. The machine overheated and shut down itself. After inspecting the cooler I noticed that the clips on the cooler were broken and therefore the cooler was not tight on the CPU anymore.

Destroyed cooler clips

I continued with the replacement of the graphic card and USB PCI card and started the machine. All was working again.

So I ordered on eBay some spare parts for the cooler clips to have a backup PC ready again in a few weeks.

Captains Side – Master Caution, Fire Warning & Six Pack

I got my hands on a 2nd hand Master Caution and Fire Warning button as well as a six pack for the captains side from Opencockpits.

For those to get installed the whole captains side panel had to be replaced. It was replaced as reworked with some additional details and painted in black instead of grey.

Placement after drilling

Then it was painted in black.

Now it was time to make the connections, but sadly the LEDs from the sixpack wont show up… I checked and double checked it. No mistake. As the modules are from Opencockpits the V+ is 5V. Pokeys is only delivering 3.3V. 🙁 So I tested it with 5V directly and it was working. Now I needed a plan for a Pokeys connection.
My plan was to buy an eight relay module which are working with Pokeys – I already have one relay in place with my strobe card.

After connecting and powering on, the result looks very good and I am happy with it.

Captains / First Officer Glare Lightning Panel

A long missed part was now built in. The captains and the first officer glare lightning panel. With this you have the option to Dim the PFD, ND, EICAS instruments. They are connected to the Pokeys57E card and are fully functional within Prosim.

The panels are also backlit, but not with LED strips – On this ones I used normal round 5mm LEDs. Drilled a 5mm hole and mounted them from the back to make a spot light on the corresponding engraved text. To fix them I glued it on the back.

Also 2 rotary switches are built into the captains side, with them its possible to select the manual values for N1, etc in the MIP panel.
