Actually, The quality of the outer view is the least important thing in the flight simulators. Most of the time you don't look outer view instead of instruments, like the real world flights.

Simulator Solutions is a business making/selling components for flight simulators; but they are not building complete simulators. This 747-400 Full Flight Simulator was a pet project for them. And for the people commenting that it is DIY because it was not made by Boeing, well... Sorry; Boeing is not making any flight simulators. Flight Simulators are made by (only a few) companies specializing in in this type of product :¬)
Been on the real Boeing 747 simulator, which feels exactly like flying, except with having a whole load of students inside they had it in a limited motion mode, so it would not do the full range of motion. Then we got to see it running from outside, where it sat a floor or so up in normal use, to get the full range of motion it was capable of. we could watch the video shown inside, on the Sony projection TV sets, on some smaller Trinitron monitors.
thats the Only way id "fly" if i have any say in the matter lol :p iv been in a medivac from a really bad dirtbike accident but dont remember any of it thank god.. thanks for the video man that was pretty cool

My old friend PETER G has an older 747 in his back hard and has been modifying it to interfece with flight sims.. He has done something like what your friends are doing he has stuck it on the back of his suburban house ! Its huge !
How cool! Ya the 400 is older, but at least the simulator has a glass cockpit - verses the old steam-punk gauges. The last 747 - 8 was just released - with a longer fuselage.
7:40 "...all these massive computers...": I'm curious. Why all the big servers? You could buy all the computer power you needed to do that for under $200 each (4"x4"x2" cubes...that could fit in one shoe box). The real feat is acquiring all the data you need for the simulated visuals. Where did they get that?
Good afternoon, Engineer Jones, I have a Sorensen LH 75-5 power supply, with a problem since it does not adjust and it will run into around 107 vdc, just by moving the current knob a little so I bought it and I want to repair it some data Could you help me engineer, I'm from Mexico, I hope you can help me, I'll send you a video of what my power source did Sorensen, thank you engineer .
No doubt they want to run it with the next edition of Microsoft Flight Simulator 2020. Microsoft is not going to put Windows 7 on the system requirements with the support about to run out.
@@Balthazar030 Well if they have a bunch of PCs, it must be able to run the simulation across a bunch of nodes, even if it is single-threaded. I would assume you could run multiple instances of the sim program on a single computer if you can have multiple instances spread between computers. If not, they could combine all the separate machines into one server running separate VMs, with different operating systems for each VM if needed. Then each VM would have, say, 2 cores and a few GB of ram. But maybe you would want to go Intel with fewer high-clock cores.
@@dannooo548 Or use 3rd gen Ryzen stuff. The new Epycs are sick. The new Threadrippers will probably be as well. So no need for Intel for that. Also their higher core count Xeons don't have clocks that high.

I'm building a Kerbal Space Program instrument panel that will fit into my desk. Nothing remotely as fancy as this, but I got a real Flight Director-Attitude Indicator that I want to use as my Navball. It's an ARU-11/A, and I think the power/reference in is supposed to be a 120VAC 400 Hz source, and I think the synchro inputs are supposed to be 28VAC... _I THINK._ I need to design a controller that takes the digital data from the KSP serial IO communication mod, and my 400 Hz reference, and creates the 10 outputs necessary to drive the unit. I'm only 90% sure those voltages are correct, and I have NO IDEA how much power is required for the Power/Reference, or for any of the individual synchro inputs. I'm also unsure of how to couple this. I was thinking of using some of those integrated audio amplifier chips, the kind in a SIP package with holes for heatsink mounting. I figure those are designed to drive inductive loads, and can push some power. Part of my lack of knowledge, is in regards to whether I even need them for all 10 inputs. Obviously, I need to provide power on the reference input. Don't know if I need any significant power driving for the three synchro inputs though. I'm still unsure how to couple the outputs. I'm guessing I'll need transformers to get the voltage coupled up to where it needs to be. I'm thinking that on the secondary side, I'd tie one side of each triplet of transformers together, to create a Y configuration, and then attach the three synchro inputs to each of the other three secondary leads. I'm thinking I'll have to keep the outputs of the audio drivers isolated from each other when feeding them into the primaries. One of my concerns is even finding transformers that will even do the job. I'd be curious how they drive instruments that expect synchro signal sources.
Not entirely sure what your answer is, but you'd be much better off typing this up on the forum. Im sure there are a lot of people over there that can help with this.
Stay tuned - I think that Dave will do another video on Synchros and Resolvers. Fascinating things - it took us two years to develop a digital interface to these analog units...
@@simulatorsolutions This sounds very relevant to my interests! I definitely belive it could take time to get it right! I used to work for a company called Tachtronic Instruments (not to be confused with Tektronix). I mostly worked with brushless motors and particularly, the drives. 3-phase units that switched outputs of 295V @ 45A. We also made synchros, which I helped with from time to time, usually when we got busy. For some time, I'd considered the possibility of just buying some surplus synchro control transformers, and mechanically driving them with a traditional motor solution, but I realized that was a bit convoluted. I have a thread on the EEVblog forum where I theorized about how to do it, but I'd not actually formally designed anything, much less completed the project. Work got busy, and it sat on the back burner for a couple _years._ I was still playing KSP version 0.25 when I first began the project! Anyway, My theoretical solution was as follows: • Analog steps •• Digital steps • A hardware generator creates a 400Hz sine wave • The 400Hz sine wave is fed into a pair of Op Amps: One inverting and one non-inverting. This creates two sine waves 180° out from each other. • The two sine waves are fed into an analog switch IC. The microcontroller can select the inverted or the non inverted signal to pass through. • The selected sine wave is fed into the reference of a 12-bit MCP4922 DAC. • The microcontroller sets the scaling of the DAC, allowing the DAC to function in multiplier mode, attenuating the sine wave on the reference. _For reference, there are a total of 9 analog switches, and 9 DACs, three per axis, for each of the three different axes. Each circuit is just repeated 9 times._ •• The Microcontroller receives serial data containing the Yaw, Pitch, or Roll angle. (Each axis will be a separate PC board, and likely have it's own microcontroller). •• The microcontroller will add 120 and 240 to the angle received, then check if any results are 360 or greater, and if so, subtract 360 from the result. •• The three values are used to look up the attenuation value from a lookup table of sine values. (I think that might be easier than trying to calculate sine. Not sure) •• Each of the three values returned are checked to see if negative. If negative, the associated analog switch has it's state set to select the inverted sine wave input. •• The absolute values are sent to the three DACs of each axis. This allows the DAC to function as a multiplying DAC, scaling the analog sine wave on the reference. • The output of the three DACs are fed into audio amplifiers. • The three audio amplifiers are fed into transformers to couple into the synchro inputs of the FDAI. (this • The non-inverted reference is fed into an audio amplifier, and is fed into a step up transformer to power the FDAI and provide it the reference source.
@@simulatorsolutions My favorite way to explain a synchro visually is to hook it up to a 4 channel scope, set the reference up top, and then line up all three outputs of the stator below it (so they overlap). You can visually perceive the angular rotation of the outputs when doing that, and you see how all the zero crossings stay in phase. I can't tell you how many times I've seen people think these work more like a resolver. Very different beasts! Of course, they are visually interesting on a scope as well. All equally interesting. Really cool demo, if you ask me!
Yeah, like desktop PC for this sort of stuff is a bit silly, also replacing those to newer models would cost probably the same as one good enough server
Mostly due number of screens and inputs. It definitively could be reduced to smaller number of computers, but it is hard to find a single motherboard that will support so many inputs and outputs, even with PCIe expansion bridges, and you might be bottlnecking some stuff. Multiple machines are probably cheaper overall and easier to troubleshoot or replace components.
Because one task by computers is better than only one computer doing several tasks. By example, X-plane and FSX, and maybe P3D are designed to be able to use several computers at the same times. One dedicated to simulation, one per view, one for others tasks. The goal, earn FPS and simulation with minimum latency. In X-plane if you are using a second screen on the same computer, you will have a fps drop.
Could they not ditch Microsoft Windows and migrate to Linux Mint 19.3 CINNAMON (Tricia) 64bit and install Wine64+Winetricks64+zip.dll and then they could run their simulator and maybe they should think about using GIGABYTE AORUS ZENITH Extreme X399 motherboard based systems with the 32 core 64 thread Threadripper with 1TB of DDR4 3200MHZ RAM and AUSTECH EN9500GT boards and Corsair PSU's and whatever SSD that they want possibly 100TB Data Center SSD's.
Great video Dave , I had the luck to try an Airbus simulator many many years ago. I couldn't make it out but did you feel and hear the gear thump up into the wings?
What flight sim software is this? He mentioned that he would run the java code on a cortex small computer or did he mean some java code of otther parts?
Real pilots sometimes use them. Training and getting into good shape on them is way cheaper, and can be done more frequently too. Sometimes you can even log official flight hours on them.
REAL Professional pilots are required to use Sims every 6 months, and are only considered "Training Time" OR Flight Sim Time for logbooks and NOT REAL flight time. Just FYI, take it ez. Tom in NV
@@lt4324 Fair enough, I do not know details. Make sense tho, I did mean "log it in logbook", not actual "flight time". Sorry and thanks for the correction. Some professional pilots just like to do sims bit more often, especially weird scenarios.
Is the motion control/hardware integration layer java based or is the whole simulator running on java? O.o Generally I've seen FSX and X10/X11 layers to interface with the hardware. But I think that only FSX can properly be synchronized into multiple instances. (I've tested X11 a yet ago, with the full world mapping, that thing is heavy! I have a decent hardware but having 8 core and 16gb of ram completely filled was a little scaring. Looks like that simulation is quite resource intensive) I would have used a rack server with VM and pcie passthrough to render each display.
A small VB based application feeds the X, Y & Z acceleration values from the Simulator Software (PSX) to the motion computer over a serial link. The hardware integration is provided using a small Java app that connects the SimStack boards to PSX. Then there is a .NET application that links the visual system (Perpar3D) with PSX. The visuals are being run from a single computer using a high end video card with multiple HDMI/DisplayPort outputs. Hope this helps.
Why the hell are they starting the engines while in parking position at the gate? No waypoints set on the navigation. Uses reverse trust for pusback.. my goodness. They are using checklists and they know what the different switches are for. But it seems they never saw a real sequence from cold and dark to take off :D
@@sparkplug1018 Not strictlty true... thet fly on the VATSIM network like many others. VATSIM is the Virtual Air Traffic Simulation network, connecting people from around the world flying online or acting as virtual Air Traffic Controllers. This completely free network allows aviation enthusiasts the ultimate as-real-as-it-gets experience. Air Traffic Control (ATC) is available in our communities throughout the world, operating as close as possible to the real-life procedures and utilising real-life weather, airport and route data. Look at vatsim.net for more info.
@@davidpalmer9780 Interesting, id been told most of them are or were IRL ATC. Pretty cool that its broader then that, and others genuinely have the passion to learn how to do it to that level.
I don't understand. .. Who has programmed the simulator? There are thousands of sensor inputs and switch inputs etc and they have to communicate with air data computer, autopilot etc. ... That is extremely complicated. I don't understand this. Who has made the program, the software? Etc?
omg mr jones Im sooo envy..in the electonics world you are living the dream..god bless you however I know you are an aithiest sir..lol..love ya brother
18:51 What are the two blank dials on the pilot's side between the two big screens? Seems to be dummy placeholders. Old style level indicator and altimeter perhaps?
Dexxter they seem to be placeholders for the standby instruments. So in case a display failure, or engine, or power, they will continue to operate, through a different battery system, which only they run on.
Supposedly these simulators are so realistic that pilots can be trained on these and immediately fly an actual aircraft with passengers and all after being fully trained on the simulator.
Thats sort of correct. A new pilot will still need a certain number of flight hours in the simulator, plus a certain number of flight hours as a first officer in the actual aircraft with a captain who is certified to train new pilots. So yes you can get all of your type ratings in the simulator, but theres still a good amount of training required in the actual aircraft.
There are some very affordable, off the shelf motion systems for DIY home simulators. I have started on one for my iRacing simulator. And if you don't know what iRacing is, then dont worry. Lol

• The 400Hz sine wave is fed into a pair of Op Amps: One inverting and one non-inverting. This creates two sine waves 180° out from each other.
• The two sine waves are fed into an analog switch IC. The microcontroller can select the inverted or the non inverted signal to pass through.
• The selected sine wave is fed into the reference of a 12-bit MCP4922 DAC.
• The microcontroller sets the scaling of the DAC, allowing the DAC to function in multiplier mode, attenuating the sine wave on the reference.
_For reference, there are a total of 9 analog switches, and 9 DACs, three per axis, for each of the three different axes. Each circuit is just repeated 9 times._
•• The Microcontroller receives serial data containing the Yaw, Pitch, or Roll angle. (Each axis will be a separate PC board, and likely have it's own microcontroller).
•• The microcontroller will add 120 and 240 to the angle received, then check if any results are 360 or greater, and if so, subtract 360 from the result.
•• The three values are used to look up the attenuation value from a lookup table of sine values. (I think that might be easier than trying to calculate sine. Not sure)
•• Each of the three values returned are checked to see if negative. If negative, the associated analog switch has it's state set to select the inverted sine wave input.
•• The absolute values are sent to the three DACs of each axis. This allows the DAC to function as a multiplying DAC, scaling the analog sine wave on the reference.
• The output of the three DACs are fed into audio amplifiers.
• The three audio amplifiers are fed into transformers to couple into the synchro inputs of the FDAI. (this
• The non-inverted reference is fed into an audio amplifier, and is fed into a step up transformer to power the FDAI and provide it the reference source.
@@simulatorsolutions My favorite way to explain a synchro visually is to hook it up to a 4 channel scope, set the reference up top, and then line up all three outputs of the stator below it (so they overlap). You can visually perceive the angular rotation of the outputs when doing that, and you see how all the zero crossings stay in phase. I can't tell you how many times I've seen people think these work more like a resolver. Very different beasts! Of course, they are visually interesting on a scope as well. All equally interesting. Really cool demo, if you ask me!
How much? Where to buy?
Great videos, was he radioing an actual air traffic control or another department at simulator solutions?
it was an AI called luna-flyer
holly crap...that's dope!
Very impressive.
I don't understand why they need so many computers.
One for each display in the cockpit + misc others for control.
I was expecting a single large server with a host of virtual machines / multiple video cards. They need to contact Linus Tech Tips.
Yeah, like desktop PC for this sort of stuff is a bit silly, also replacing those to newer models would cost probably the same as one good enough server
Mostly due number of screens and inputs. It definitively could be reduced to smaller number of computers, but it is hard to find a single motherboard that will support so many inputs and outputs, even with PCIe expansion bridges, and you might be bottlnecking some stuff. Multiple machines are probably cheaper overall and easier to troubleshoot or replace components.
Because one task by computers is better than only one computer doing several tasks.
By example, X-plane and FSX, and maybe P3D are designed to be able to use several computers at the same times.
One dedicated to simulation, one per view, one for others tasks. The goal, earn FPS and simulation with minimum latency.
In X-plane if you are using a second screen on the same computer, you will have a fps drop.
Could they not ditch Microsoft Windows and migrate to Linux Mint 19.3 CINNAMON (Tricia) 64bit and install Wine64+Winetricks64+zip.dll and then they could run their simulator and maybe they should think about using GIGABYTE AORUS ZENITH Extreme X399 motherboard based systems with the 32 core 64 thread Threadripper with 1TB of DDR4 3200MHZ RAM and AUSTECH EN9500GT boards and Corsair PSU's and whatever SSD that they want possibly 100TB Data Center SSD's.
grate work :-)
Did they just take off without setting flaps?
They were running the checklist and at 18:11 verified the 'Flap 10' was planned and selected.
Great video Dave , I had the luck to try an Airbus simulator many many years ago.
I couldn't make it out but did you feel and hear the gear thump up into the wings?
Id imagine they have that programed in swell. The pilots will usually hear the nose gear come up and the doors close. Its sort of an odd sound though.
Yep! I was waiting for it and it felt and sounded spot on!
What flight sim software is this? He mentioned that he would run the java code on a cortex small computer or did he mean some java code of otther parts?
Im pretty sure I flew with Rod out of YSBK circa 2001.
0:26 100% terrific
They're flying for VATSIM network"THE WORLD FLIGHT". I did the same.
Real pilots sometimes use them. Training and getting into good shape on them is way cheaper, and can be done more frequently too. Sometimes you can even log official flight hours on them.
REAL Professional pilots are required to use Sims every 6 months, and are only considered "Training Time" OR Flight Sim Time for logbooks and NOT REAL flight time. Just FYI, take it ez. Tom in NV
@@lt4324 Fair enough, I do not know details. Make sense tho, I did mean "log it in logbook", not actual "flight time". Sorry and thanks for the correction.
Some professional pilots just like to do sims bit more often, especially weird scenarios.
Is the motion control/hardware integration layer java based or is the whole simulator running on java? O.o
Generally I've seen FSX and X10/X11 layers to interface with the hardware. But I think that only FSX can properly be synchronized into multiple instances. (I've tested X11 a yet ago, with the full world mapping, that thing is heavy! I have a decent hardware but having 8 core and 16gb of ram completely filled was a little scaring. Looks like that simulation is quite resource intensive)
I would have used a rack server with VM and pcie passthrough to render each display.
I think the hardware programming language for the interface is "java like". More on that when I go back there.
That's so cool!
Thanks for the reply!
A small VB based application feeds the X, Y & Z acceleration values from the Simulator Software (PSX) to the motion computer over a serial link.
The hardware integration is provided using a small Java app that connects the SimStack boards to PSX.
Then there is a .NET application that links the visual system (Perpar3D) with PSX. The visuals are being run from a single computer using a high end video card with multiple HDMI/DisplayPort outputs.
Hope this helps.
Why the hell are they starting the engines while in parking position at the gate? No waypoints set on the navigation. Uses reverse trust for pusback.. my goodness. They are using checklists and they know what the different switches are for. But it seems they never saw a real sequence from cold and dark to take off :D
Who does the ground control? Are there people outside the plane simulating ground control as well?
Its a group of people who are IRL air traffic controllers doing it for them. These people really take this seriously and to a whole other level.
@@sparkplug1018 Not strictlty true... thet fly on the VATSIM network like many others. VATSIM is the Virtual Air Traffic Simulation network, connecting people from around the world flying online or acting as virtual Air Traffic Controllers. This completely free network allows aviation enthusiasts the ultimate as-real-as-it-gets experience. Air Traffic Control (ATC) is available in our communities throughout the world, operating as close as possible to the real-life procedures and utilising real-life weather, airport and route data. Look at vatsim.net for more info.
@@davidpalmer9780 Interesting, id been told most of them are or were IRL ATC. Pretty cool that its broader then that, and others genuinely have the passion to learn how to do it to that level.
I don't understand. .. Who has programmed the simulator? There are thousands of sensor inputs and switch inputs etc and they have to communicate with air data computer, autopilot etc. ... That is extremely complicated. I don't understand this. Who has made the program, the software? Etc?
14:36 -What's the frame-rate on those flat screens? I've never seen them flicker like this! A 4K artifact perhaps?
These are 1080 projectors likely dlp
Good job guy's but seriously using thrust reverse for pushback?... I followed WF19 through Simfest/Goli's livestream and often saw QF25 pop up :)
All I can say is: Wow!
this is great great GREAT. wow
omg mr jones Im sooo envy..in the electonics world you are living the dream..god bless you however I know you are an aithiest sir..lol..love ya brother
18:51 What are the two blank dials on the pilot's side between the two big screens? Seems to be dummy placeholders. Old style level indicator and altimeter perhaps?
Dexxter they seem to be placeholders for the standby instruments. So in case a display failure, or engine, or power, they will continue to operate, through a different battery system, which only they run on.
They should buy a miner board and drive all non-intensive displays with it
Supposedly these simulators are so realistic that pilots can be trained on these and immediately fly an actual aircraft with passengers and all after being fully trained on the simulator.
Thats sort of correct. A new pilot will still need a certain number of flight hours in the simulator, plus a certain number of flight hours as a first officer in the actual aircraft with a captain who is certified to train new pilots.
So yes you can get all of your type ratings in the simulator, but theres still a good amount of training required in the actual aircraft.
8:40 - "Relatively fan-less"?
dlp projection with colorwheel .. argh..the rainbows
Any news from the custom µSupply LCD ?
Now do an A-10C cockpit flight sim. :D ty
There are some very affordable, off the shelf motion systems for DIY home simulators. I have started on one for my iRacing simulator. And if you don't know what iRacing is, then dont worry. Lol
swiftrick15 Do they make any that will support a real car?
@@caddyguy5369 the university of Iowa has one. NADS-1 is a car shell inside a dome on a motion simulator. It's probably not going to fit into your home, but there you go.
@@caddyguy5369 With the right support...and maybe just a shell. They specify load ratings...more money...more load
also just bought myself a new laptop and life is soooo much better..I;m loving life..off to do a hike at my btothers place in the sierra's it's beautifu; here..cheeers mate
Great video. Main channel worthy imo
Young semu-pilots you forgot a very important thing: Your seatbelts !!!
I'd like to see them take cavemen and fly into tall buildings...and into a building as low as 5 stories after a 270 degree final turn...at full speed. Can it be done?
So cool
why would you do that for a boring old plane like a commercial jet... if you're gonna do this kinda thing, might as well go full out on it and do fighter jets!
Most expensive? More like most ancient
Ok nice. Great Job. But HOW MUCH IS IT?
