Title: Memphis 727 Build
Post by: skyline223 on August 10, 2018, 08:52:13 PM
Greetings to all!

Following up on my introduction, this will be the proper build thread for my Boeing 727 home simulator. I'll give a more thorough history here. Without further ado, here's the story:

I was bitten by the flight sim bug early in life. My first copy was Flight Simulator 2000 at the age of 7. While I likely did a lot more stalling than flying, I was hooked. As I grew older, my interest grew respectively. As a high school student, I was exploring every possibility to make my desktop flight sim setup more immersive and complex. I came to the conclusion that the next step for me was to build a cockpit enclosure of some kind. With the help of a high school friend, we drew up some initial plans for a generic sim pit that would roughly resemble a 727/737 cockpit. I was very fortunate to have a mother who was a 35 year employee at Fedex. With that connection, we were able to arrange a tour of the FedEx simulator facility here in Memphis. This is where the story gets good.

The purpose of the visit was to spend some time in one of the company's 727-200 level D sims - taking measurements of every nook and cranny of the cockpit. These measurements were to serve us in building our generic sim pit. Of course, I had explained everything to our sim tour guide that I have just explained to you. As we were sitting in the level D sim, a light bulb went off in his head. He said to me and my buddy - "Guys, if y'all are serious about building a 727 sim, I think I have something that you are going to want to see."

He led us down a hallway with a couple burned out fluorescent bulbs, and we turned to a door with dust on the knob. Creaking it open, inside the room sat a Boeing 727-100 Cockpit Procedures Trainer (CPT). Our tour turned to us and said "I can't make you a guarantee yet, but I'll talk to the boss, and I bet you guys can have this thing. You would be doing us a favor if you could dismantle it and get it out the door for us. No one comes in here to use this box anymore."

The CPT just as I saw it when we opened the door

A few days later we got good news. "Come get it!" Armed with a toolbox and a UHaul truck, we spent three days dismantling the CPT and moving it across town into my parents house (bless them!)

(https://image.ibb.co/fnCb0p/5176234.jpg)

Here's what we knew of the CPT as it sat:
-It was most likely originally delivered to American Airlines sometime in the late 70's.
-The manufacturer is unknown.
-The shell is all fiberglass and appears to be a one-off construction.
-The CPT had little to no actual functionality. All gauges were faux and the windows were opaque. The trainer was mostly used by new hire flight engineers to learn flows.

As I began to piece the sim back together, my goal was to get it flyable as soon as possible. I built a three projector setup using very basic 4:3 projectors and flat screens. This worked quite well for some time. For the MIP, I used the CPT original panels and fitted LCD screens behind them to display virtual gauges. This also worked pretty well, but certainly left something to be desired in terms of realism. The overhead was interfaced to FSX using FDS InterfaceIT cards. This was a good solution since no avionics suite was available for the 727 in FSX. The F/E station was left alone since again, the software logic did not exist to interface it anyway.

FedEx came through again and helped me out obtaining a set of Ipeco pilot seats, as well as F/E and forward observer seats. Other parts were collected through APHS. The initial build lasted about 6 months before the sim could fly full flights start-up to shutdown without keyboard intervention. (Circa 2010)

The build circa 2010 at my parent's house
(https://image.ibb.co/hEy0Vp/6538821_orig.jpg)

I flew and enjoyed the sim for a few years until a local flight school became interested in using it for Crew Resource Management training. I moved the sim from my parent's house down to the local flight school. Since minimum downtime was a priority, I didn't have any time to make upgrades or improvements. I disassembled the sim, moved it 15 miles, and reassembled it all in a week's time. (Circa 2013)

The sim circa 2012
(https://image.ibb.co/g6upLp/7726310_orig.jpg)

The school ran a program for foreign pilots who would go from zero flight experience to multi-commercial in a couple years. The 727 sim became the the last step after completing their commercial in a Beech Duchess. It aided them in learning how to work in a multi-crew environment before heading back to Asia to obtain their type ratings. The sim worked great for this, but after a few years of usage, the school made the decision to invest in a FDS A320 sim that has served them well. Since most of the students would go on to fly the A320, it was a great choice. (Circa 2016)

Alas, the 727 was back in my hands for home use. The problem was, during the time it was at the flight school, I got married and moved into my own house. For a certain period, I couldn't come up with a place to put the sim. The only room in my house where it would possibly fit was a upstairs room with a vaulted ceiling. Every time I looked at the room, I convinced myself that the sim, and better yet a visual system, would not fit. Setting up the sim at a different location was really not an option to me. I knew that the next time I built the sim, I would really take my time and make improvements I always dreamed of. With that said, I knew that if the sim was away from home (perhaps a hangar, for example) that I would struggle to find the time to make special trips out to work on it. For this project to succeed, it had to be at home.

In the time that the sim sat in storage, the second stroke of luck graced upon me. I came into an opportunity where I acquired a real loaded MIP, overhead, and many parts of the F/E station. (I recently discovered that these parts once belonged to Scott, XOrionFE.) Suddenly this project was setup to be taken to a new level. I would now have the chance to build it with all real gauges! This is where I will be doing the most learning. The goal is to start with interfacing the engine gauges and move outwards from there. I can't tell you how excited I am just to have backlighting! (CPT panels were not backlit)

The complete MIP and overhead

(https://image.ibb.co/cY6m0p/img_5458_orig.jpg)

Back to the sim: the 727 sat in storage for almost two years while I brainstormed on where it would go. Finally I got the urge to actually take some measurements of that upstairs room. Amazingly, I realized the sim would fit. Just barely. I wasn't sure of the visuals, if I had to go the flatscreen route to make it work, I would. Though, the dream has always been a curved projector screen.

Now here we are - phase 2 (maybe 3) of my 727 project and I have high hopes for it to be better than ever. I have been working to get all the parts moved over to my place bit by bit, but have also started to focus on building a curved screen. I'll be starting with a fresh floor build, a fresh computer build, and all new visuals. The current plan is to run the sim on X-Plane 11 with the FlyJSim 727 v3. This time around, the priority is to get as much functionality out of the systems as possible. I believe the sky is the limit!

Here we are as of today. I have built a fresh floor from high density MDF. It had to be low profile for the sim to fit in the room, so an elevated platform was not an option. I have moved the front section of the shell up into the room and have it zip-tied together for now. It will get final fasteners once the visuals are complete. Note that the interior liners are not yet installed, and the back half of the shell will come down the road when as well when I am satisfied with visuals. I am leaving flexibility to move shell sections around as needed to work on the screen and mount projectors.

(https://image.ibb.co/eBzw39/IMG_2465.jpg)

Here are the early stages of my curved screen build. I am really working off the seat of my pants here since I have VERY limited space and working around the awkward vaulted ceiling. This is a coat of primer as I continue to work and smooth out the screen surface. Final coat will be an even bright white. Due to the space constraints I am still prepared for this screen NOT to work out, but I had to give it a good run for my money! I will have some short throw HD projectors to play with in the next few days so we will see how it goes. Again, once I get the visuals to the point where I am happy with them, I'll be able to button up the shell and really hit the ground running on getting the cockpit put back together!

(https://image.ibb.co/crKJGU/IMG_2468.jpg)

That's it for today, stay tuned.

Time for an update.

I have been working on various projects related to the sim the past few days as much as I can after work. The biggest progress to report is in the visual system. I have mounted all three of my new HD projectors and therefore am making some progress on the visual. Now for what might be the most challenging part yet, warping and blending.

Can any of you recommend a good warp/blend software that is affordable and functional?

Before this project the only software I knew of was NTHUSIM. I see they are no longer offering the software which seems a shame, but I remember is certainly was not cheap. I am looking for recommendations here!

Here's the visual as it sits now with no warp/blending.
(https://image.ibb.co/dtMx5z/IMG_2564.jpg)

Three BenQ TH671ST mounted up nice and cozy

Forward view looking pretty nice out of the F/O window
(https://image.ibb.co/etmmyK/IMG_2566.jpg)

Other things I have been working on but no pics yet.
-I built a fresh computer for the sim. Intel i7-8700k, MSI RX 560 GPU, liquid cooled, in a rack mounted case. Very pleased with the performance I am getting out of this PC!

-I have been working on building a new MIP support frame. My original frame had three issues
1. It was pretty ragged from many years of being moved around and modified
2. It does not accept real panels very well since it was built for the CPT
3. It is sized to accommodate 727-100 panels. The 727-200 has shorter Capt. and FO panels. The new frame will be to the correct dimensions to accommodate the real MIP.

So the next step now that the projectors are mounted is to start piecing together the shell, finish the MIP support, and really start to see the sim take shape. After that, the real nitty gritty comes as I'll focus back on the interfacing project.

Hey Nat,

I didn't forget about the visual on the A320, it is marvelous! I had no doubt you would take good care of me! I just knew I didn't have the budget (or space) for that screen, and as for the software - I didn't want to call you up and ask you just for the software - I know you make your living selling complete visual solutions! I hope you understand and no hard feelings. The day the sim moves into a bigger room you are getting my first call.  :)

No worries Will!
You're right I generally only supply complete kits for FDS, but for friends don't be shy, email me :)
Ive used FlyElise many times so I can help you with that too, but I know you're a very smart cookie!

I appreciate the kind words, Nat, it is no surprise I could use a little help!

First an update on progress of the last couple days.

First order of business was to finish off the outer sections of the screen. Lots of sanding, painting, sanding, until the finish was satisfactory.

(https://image.ibb.co/iWUGne/IMG_2571.jpg)

Very happy with the end result of the screen. It is far from pro quality, but for a low budget (entire screen cost around $50 to build) and very tight space constraints, I am satisfied.

(https://image.ibb.co/nbu5fz/IMG_2592.jpg)

After working with Immersive Display Pro, I achieved an initial warp and blend that I was satisfied with. Here I am showing the result using just a sample image on the screen.
(https://image.ibb.co/khhDYK/IMG_2589.jpg)

The issue I am having is that Immersive Display Pro is VERY finicky about running X-Plane or Prepar3D in fullscreen mode. Whenever either piece of software is run in fullscreen, the warp and blend is suddenly no longer applied. I try to toggle the warp on and off but no change occurs. Very frustrating! Somehow I managed to get it to run X-Plane with warping for a little while, but it would flicker on and off every minute or so.  :o
I have exhausted working with different setting combinations with little success so I'm going to call it a night on this one. Any advice or help is appreciated.

Finally with the physical work finished on the visual I was able to move the back half of the shell in and get all the outer shell pieces bolted together. This shell is simply massive, especially in this small room!

If you need a PM, I'm in Southaven.  5 WorldFlights under my belt, and I work for the local purple box hauler in Flight Control.

I might still have our 727 Ops Manuals around somewhere (on PDF).

Hey Doug, that is awesome! I would love to have you up sometime! Definitely once I get this box flyable again, it would be great to to some proper multi-crew flights.

Today I can report I finished the majority of the frame to hold the MIP. Still a little tweaking to do on a couple pieces that are interfering with each other, but it is far enough along just to setup the panel and get a look at it. I got a rush just sitting down and looking at this panel. It is almost unimaginable how much work lies ahead in lighting this panel up, much less interfacing it, but I am beyond excited! Just a teaser:

In the meantime, still struggling getting Immersive Display Pro to act right.

Small progress but very notable, I have the visual working fantastic. The magic solution was uninstalling all GPU drivers and reinstalling fresh. 140+ FPS in P3Dv4 which is all I had time to try out.

Thanks! The trainers are nice, I find them easier to work with versus a real cockpit structure. The modular construction is wonderful. I've always been tempted to convert to 737NG, but I'm in too deep now!

Well the past two days have been very exciting. I have had the privilege of scavenging a salvage 727-100 for parts. Since my cockpit is mostly "complete" as far as parts go, I went for things that will add further to the realism and help with the build. The list of what I pulled:

-100+ female Cannon plugs
-Cockpit door
-Upper interior trim
-Left rear interior trim
-Rear observer's table, a/c vent and reading light
-4 Ashtray/cupholder units for all crew
-Aural alert box (houses overspeed clacker, fire bell, intermittent and constant horn, speaker)
-Cabin door operation panel (outside of cockpit bulkhead)
-"Return to seat" light from lavatory
-Miscellaneous window trim
-Pilot's map light
-Rain repellent bottle and bracket
-Loaded spare bulb and fuse box
-Rear wall panel that holds manual gear lever, crash axe, fire extenguisher

So a very good day of picking has concluded. I'm excited to get these parts installed, the aircraft was a 1966 727-100 originally delivered to Pan Am and retired with FedEx. The outside of the cockpit door still shows the original Pan Am "wallpaper"

Cockpit side of flight deck door
(https://image.ibb.co/g2fqoK/IMG_8091.jpg)

Very unique piece of interior trim. This is the most aft center piece of trim that has the large cutout for a sextant! I have an original airline sextant and hope to rig it up in the sim for historical display purposes.
(https://image.ibb.co/n3hs2e/IMG_7821.jpg)

This photo shows almost the exact location in the cockpit where this cutout is. I'm very much looking forward to this!

My box of 100+ cannon plugs. Hopefully enough to get me through this project! Very excited and honored to have these.
(https://image.ibb.co/ezzi8K/IMG_4495.jpg)

I might need to replace a bulb in this unit, otherwise passengers might get the wrong idea  :laugh:

Thanks Marco! I have the complete FE panel. I have not interfaced it up to this point. The sim previously ran FSX and at the time I couldn't think up a way to really get it functional. This time around, with goals to run XPlane and FlyJSim 727, I am hoping to get the FE panel fully, if not mostly, interfaced. Odds are it will be about the last thing I get to though, with priority being the MIP and overhead first!

What is funny is I was recently thinking about compiling all the different registration numbers of the aircraft that have "donated" parts to the sim. I know of FedEx birds, I have parts from N484FE, N218FE, and most recently, N144FE.

The room is odd. It is 13'x14.5' with vaulted ceilings. The rear of the room has a 3.5'x13' area with standard ceilings. The sim and visual screen fits in the 13'x14' area without any room to spare. The 3.5'x13' area at the back allows enough room for the computers and a chair or two. Did a quick drawing just to help visualize.

Had a little time to work on the sim this afternoon. Continued framing up the rear bulkhead. Very excited to have the door hung and opening/closing beautifully!

I got a little bogged down the past week working on the back wall project. I didn't expect it to be so slow going, but it took forever measuring, running downstairs to make a cut on a piece, bring it up to test fit, back downstairs to make adjustments, on and on...

I was hoping putting the real interior trim panels in would be relatively simple, but when is it ever? Had to make some modifications to the panels and my shell to make them comply with each other. I'm very excited to say I finally have the back wall finished up tonight. Original observer map light and A/C vent both functional. Rear observer jump seat will go in tomorrow, and I have an old Pan Am first aid kit on the way to finish off the back wall - should be pretty neat.
(https://image.ibb.co/eaGTkK/IMG_2870.jpg)

Next up I'll continue to work my way forward in the cockpit installing interior trim and hopefully will get that finished up this week.

More forward progress today. Finished up some last details on the left back wall. Installed the aft observers seat, wall hooks, and put in a small bookshelf underneath the observer table. It is a unit I found at IKEA and painted to match. It is the perfect size for my slow growing collection of manuals.
(https://image.ibb.co/g3RnFK/IMG_2883.jpg)

Next I painted the outer back wall of the sim. I went with a simple satin white that will be a good canvas for some decals I have planned - more details coming on that a bit later. To the left of the door is the "Return to seat" light and below that is a cabin lighting panel that I have wired to control the light on the outside of the sim. The return to seat light will be wired to illuminate when the seatbelt sign is switched on via the overhead.

This is also a pretty good picture to show how tight the shell fits in the room with the vaulted ceiling!

A few more days gone by, a few more bits of progress to report.

F/O side upper eyebrow trim is installed. Installed LED's in the original dome fixtures, and mounted the 28V original map light. Anxious to hook the lights up to power, but that will be further down the road.
(https://image.ibb.co/bFzwX9/IMG_2907.jpg)

Hauled the F/E panel up the stairs and mounted up in the sim. Still a static display piece for now. I look forward to interfacing it later on. It did get a little love today though. I replaced the flood lighting with warm LEDs - hard to beat the low current draw and no heat!
(https://image.ibb.co/k8Agzp/IMG_2906.jpg)

A fun item pulled off fleabay.. original Pan Am aircraft first aid kit. Mounted up nicely on the backwall and complete with 50 year old first aid essentials.
(https://image.ibb.co/bGWX5U/IMG_2908.jpg)

Most likely the majority of time today was spent on a complete revamp on the project website and the creation of an Instagram page. In addition, I've officially named the build "The Boeing 727 Legacy Project" as my goal is not only to build a functional cockpit, but to carry on the historical legacy of the 727.

Other notable progress from today but with no pictures: I began tearing apart the throttle quadrant for a total overhaul. It will need a thorough cleaning, fresh linkages, pots, and some reconfiguration. I will make the electric trim wheels functional. Tonight I started work interfacing my Sperry SP-150 autopilot.

Hey Will,

Is your TQ a real one? What about the 2 bay ped behind it?

The TQ is not real. It is the original unit from the CPT. That being said, it was probably the best piece of original hardware in the CPT so I've kept it through the years. The throttle levers themselves look and feel very good. The 2 bay pedestal is a pain though. It does not have dzus rails so I have to improvise a bit to make things work. Here's the only picture I could find from a few years ago when I had just installed the Opencockpits radios. These will be rearranged now with the SP-50 going in. Transponder will likely move to the center "CDU bay" (for lack of a better term). The original parking brake lever is MIA so I had to make do with a covered toggle switch. I haven't looked very hard but I'd like to find another parking brake lever one day.

Thanks, Warren! I fiddled with a few different things today, but something I thought you guys might enjoy:

I acquired two Eastern Airlines 727 flight manuals, but the most exciting thing about them was the two tri-fold checklists that were tucked inside. I scanned these original checklists in, cleaned them up a bit, adapted them for 8.5"x 11" and customized with the project logo. We use tri-fold checklists at work and I really like the format. If any of you care to have the checklist, here's the link to it so you can print it at home.

I printed using cardstock paper with a slight off-white tint for the vintage appeal. Simply print the PDF double sided and then tri-fold accordingly. Enjoy!

Milestone day, the first gauge working! Big thanks to Rob Archer for the pin-out. Very exciting stuff to see the needle and digits move on this gauge. I'm currently an Arduino idiot but there's only one way to learn something and that is to do it. I look forward to diving in deeper as I go along.

Gosh, hard to believe it has been over a week since I checked in last. I have spent at least six hours every day working on the throttle and autopilot, with most of the work being on the latter. It is very slow going work reverse engineering parts that you have no schematics for.

Here is the finished product of the fully rewired Sperry SP-150. All solenoids, switches, controls, and backlighting are functional. The only remaining step is to get everything programmed correctly in X-Plane.

(https://image.ibb.co/dJeb9z/IMG_3059.jpg)

I removed 99% of the original wiring on the autopilot and started fresh. I will also leave it without the enclosure because I have limited space inside my pedestal.

I am waiting on an arduino relay expansion module to control the lockout solenoids. For now they work with manual 24-28v power. All switches and pots are wired to a BU0836X. The pitch control nose down/up and left right is recognized as a XY axis. I played with the autopilot in FSUIPC with P3D (for now, I know my way around this platform much better) and was able to fly around a little bit. Further tweaking and experimentation will be necessary, but for now I am pretty happy.

The backlighting took some time to get right. The original backlight panel had the micro incandescent bulbs that are not cost effective to replace. All but one were burned out. I removed the backlight panel and installed 3mm warm white LED's into the original lamp locations of the front panel (a little hot glue is your friend). A few resistors and we are cookin'. I'm really pleased with the end result and LED's are always better all around.

If anyone needs help interfacing a Sperry autopilot feel free to reach out to me (even if you are reading this thread in 2025). I found quite a few threads on the internet where someone would say "HEY just finished interfacing my SP-50 here it is working!" with no explanation. I'm always happy to help anyone with what I have learned if I can. PM me here or contact me through my website www.727simulator.com (http://www.727simulator.com)

The throttle is slowly coming together. I took apart the linkages, cleaned and regreased them. I installed all fresh pots which was much needed. As you can partly see in the above photo, I'm slowly repainting the throttle bit by bit and installing fresh decals. I'm making these decals from scratch in Photoshop and will upload them on here when I'm finished if anyone wants them.

Next steps will be rigging up the motorized trim wheels, trim indicators, and getting the throttle all buttoned up. That will be a big milestone. Of course, I'll be continuing to try and figure out arduino and X-Plane as I go along, because that logic will certainly be needed for the trim system.

P.S. - someone sent me a message after I made my last post asking about details of how I have the N1 gauge interfaced with X-Plane. I for the life of me can't find the message now, but to clarify, I do not have the gauge talking to X-Plane YET. I am just using the arduino as a signal generator for now. I am greatly looking forward to getting the signal from X-Plane as I gain more knowledge of arduino.

Till' next time..

Very interesting and informative thread Will.

I agree there are dozens of YouTube videos of "look what I can do" content, that are about as much use as a chocolate spanner.   ;)
It's comforting to see someone actually offering to show how it was done. So you've joined a fraternity of many like minded fanatics that all suffer from this terrible simulation sickness.  8) 8)

For future reference if you need to replace a backlight circuit, you can get a copper clad board of .8mm thick and isolation route it to accommodate SMD LEDs and resistors. You will of course need a small CNC machine to do this, but for many of us that's an essential component for sim building. Also the cost of these machines is very small when you compare some of the prices that commercial vendors charge for after market components. 
:2cw:

I've attached a pdf of the throttle labels, not sure where I got these from or who created them but they might save you a bit of time. They are NG I believe.

Keep up the good work Will, I look forward to your next installment.
Joe.

On a recent business trip to DC over the ADS-B Mandate with the FAA, I took the liberty of writing a cleaner version of the EAL 727 Checklist.  Granted, I couldn't exactly duplicate the font of the EAL Checklist, but I think I got it pretty close.  If you need the Word version - I'll be glad  to forward it your way.

I'm watching an old Delta 727 systems ground school on YT.  I got my aircraft dispatcher certificate on the 727 so I knew the systems on that beast once - its a good refresher.

Wow Doug! That is great work, I cannot imagine how much time that must have taken you! You did a great job. I'd love to have that Word doc as well. Also I think that checklist font is pretty close to a Milspec font.

Bebas Nue seemed to be a pretty decent match for the bold titles.

Again, great work - highly commended!!!!

Hi Will!  Nice work on your 727!  I was hoping to track down an old 727 "floor model" sim (older generation sims that had limited motion) that made it's way to Embry-Riddle many years ago.  It did not seem to stay there long, as I saw it sitting in a salvage yard after 9/11.  I heard it was purchased by a local firearms training outfit with the intention of being used in an FFDO training course, but that never transpired.  The sim was sold again, apparently for scrap.  What a shame.  I simply did not have the money when it would have been available to me, and besides I was sweating weather my airline would soon be gone and with it my job.  Now that I have the wherewithal to actually do this project, the parts are getting hard to find and expensive, but with some patience and perseverance it will proceed! 

  That cpt you have is sweet!  I will be following your build closely!
