- This video is about how we can fool your brain into thinking that it is flying an aircraft, featuring the Delft University of Technology's SIMONA flight simulator. By using a couple of clever tricks, we can trigger sensory illusions that are not only believable, but impossible to resist.

A couple of things that didn't make it into the video:
- 0:12 the F-18 crash is documented by the US Naval Aerospace Research Laboratory, see page 10-7: apps.dtic.mil/sti/tr/pdf/ADP013854.pdf
- 6:57 notice how when the roll gets washed out back to neutral, it returns slower than the initial excitement. This makes sure that the pilots feel the initial roll (rate), but won't sense the platform going back to zero roll.
- 13:04 the reason it's easier to compute aerodynamic and thrust forces is because these need to be calculated anyways to simulate and model the aircraft. For example, X-Plane has an option for directly outputting the aerodynamic/thrust forces along the aircraft's axes, which I could use as inputs for the animations. Computing gravity and acceleration would require determining angles and geometry, which makes the whole thing more convoluted.
- 14:16 since we now have a solution for specific force in both directions (forward and side-ways), this means we can replicate specific force in the entire horizontal plane through a linear combination of both directions. However, in the vertical direction, it's only possible to replicate short, high-frequency movements, since the simulator can't be tilted to sustain long-term forces in the vertical direction (which is in-line with gravity). For sustained vertical g-force, some sort of centrifuge would be required, like in this simulator: desdemona.eu
AND, the sim can NEVER exhibit or simulate anything above 1 gee.
@@Cyberdactyl It can actually do that short-term through quick translational movement
@@leogoe Well . . .sure. . . for like about a quarter second or for vibration effects but no +1 gee maneuvers.
High G training would be good. Besides learning grunt breathing, turning your head under high G is a challenge. Familiarization with sudden G forces during carrier takeoffs and landings. Two simulator approaches besides centrifuge are
1… perhaps a motion platform that can pitch up or down through a full 360 degrees, but not roll or yaw
2… a pilot suit with 50 tension cables attached to pull on body parts (head forward, back, down, up, left right, chest forward down back, legs, arms)
Very good point :)

You are not the brightest candle.

@@MrTommispilot Jeez dude, get your sarcasm detector calibrated.
@@fanBladeOneI enjoyed your sarcasm and humor . I’m an engineer too, apparently MrTommispilot is a bus driver in the sky. BSEE worked in Naval Aviation for 25 years
And then you listen to a physicist, who says gravity isn't real, you're accelerating up at 9.8 meters a second squared due to the curvature of spacetime caused by the Earth's mass.
It astonishes me that a pilot would take off at night, over the ocean, with everything pitch black, and not be fixated on the attitude indicator.
Yeah wtf was dude looking at if NOT that?
We scan the primary flight instruments with the
attitude indicator as the “home” gauge. Then airspeed, heading, and/or GPS , assuming we are still hand flying the aircraft.
Einstein already said that you cannot distinguish between gravity and acceleration without a reference. Very well done!
Because gravity is acceleration
@@Systox25 No, it is force. It becomes acceleration when divided by mass.
@@krumuvecis true
@@krumuvecis actually it's the curvature of space-time.
@@krumuvecisGravity is not a force. Gravity is the curvature of spacetime. The resistance to gravity (for example by standing on the earth) is a force. So standing on the earth under the influence of gravity is equivalent to an earth accelerating upwards with the 9.806…m/s^2
I had worked for a simulation manufacturer in the late 80s and early 90s in Tampa Florida and we had some pretty cutting edge technology back then. This is next generation stuff here. Exceptional video.
did you work for cae
I’ve got a 6dof platform at home. Not as fancy as the one in Delft, of course. Maximum load capacity is 150kg. Enough for a seat, three monitors and flight gear. With VR gear the motion cues are very effective. If I use the monitors the rest of the room needs to be dark or my peripheral vision picks up the room. Works great with both X-Plane and MSFS2020.
I am a sim tech at United and you would love to know we still have a 767 full flight simulator in service from CAE that was built in 1982. My favourite out of all the machines we have.
I've done my training on the new CAE Airbus A220 (Bombardier CS300/100) sim. Before that I did training on the Jetstream 32 sim from the 70s that needed a whole room just for the PC. but the Sims now are so realistic it's incredible
@@lithium25693 Contraves, CAE was our competitor. Many of our people were from CAE.
This is the best piece I have ever seen on flight simulation. I have written software for flight simulators for 30+ years; both games and actual full flight simulators. Thank you for making a video that I can use to explain the rather obscure and mysterious magic behind pilot training.
Thank you!
do you know why the actual visual quality is so bad in FFS? Ive always wondered as I feel like that would be somewhat important especially for immersion
The saddest part of the f18 pilot story is he did have visual cues for his attitude on the flight display. He just didn't trust his aircraft was telling him the truth, or failed to check his instruments in time.
Yeah you’re right. I’ve seen a lot of people question how it’s possible that the pilot didn’t use their instruments. But I think that people underestimate how strong the illusion of acceleration/gravity is in the dark. Although the HUD gives you all the information you need, it’s still only a tiny part of your full field of view, and is entirely different from having a complete horizon and sky to look at.
@@FlyByMaxI already commented separately but it fits here as well, how can a pilot ignore a pitch ladder, flight path marker, giant arrow, and computer that's screaming flight controls? Only for him to trust a single sense he has, in complete darkness.
If the story is true then he should never have been a pilot, especially in a fighter.
What if he didn't trust his iff either? He'd just shoot down a friendly because his senses are so much better than a radar that can see out >100nm
@@ka-uy8yh Between 1983 and 1993 more than 78% of 291 night take-off accidents in the U.S. alone were attributed to spatial disorientation ( source: skybrary.aero/sites/default/files/bookshelf/1124.pdf )
I understand it's difficult to wrap your head around if you haven't experienced the somatogravic illusion yourself, but the fact remains that this is a well-documented and very dangerous side-effect of our physiology that can affect even experienced pilots, despite IFR training. I do not think it is comparable to mistakenly shooting down a friendly aircraft because you do not trust your IFF. Thanks!
@@ka-uy8yh Damn, if only you had been the instructor of that guy, you clearly know everything there is to know about fighter jets, what are you doing in the CZcams comments section? Go train the best pilots of the world, your knowledge is being wasted here!
@@FlyByMax this is true, when i was a baby pilot the first time i got above an inversion my body freaked out cause it looked like i was inverted, so i understood the importance of trusting the instruments, i can't even imagine what its like in pitch black, with minimal room for error.

"ah shit, here we go again"
As someone who trains in sims regularly as a professional pilot, my experience is thus: usually the first time back in a sim after it's been awhile my brain knows "something" is wrong, and I tend to just be a little disoriented and maybe a bit queasy for the first 30 minutes. However, after a while my brain recalibrates and adapts to the sim and it becomes really cool how well it just "accepts" it. The motion is pretty well matched with the inputs and visuals. Especially that surge axis is perfect for quick jolts like turbulence or landings. Not for nothing too, having a perfectly replicated cockpit inside helps a lot, because you're leaning/reaching/turning your head in exactly the same way you would in the real airplane, and all of this motion is completely independent of the orientation of your body, so the illusion remains even when you're not sitting perfectly in the chair looking straight ahead.
I wonder if the reason your brain recognizes a difference is because there are fundamental limitations on what a sim can do, or if the sim just isn't quite accounting for everything due to cost or other non-fundamental limitations.
How does it handle a stall and altitude loss? Tipping forward? I assume it's almost impossible to replicate the freefall in the sim.
@@daysofend33 y
@@severoon Meta has done studies with VR goggles. The one that really surprised them was how much dynamic range makes a difference. When you look at the sky and it's actually bright and your pupils contract, it's a massive boost to immersion. I'm willing to bet that visual and auditory clues play a huge part. I once was in a static A320 sim so no hydraulics and I could swear the thing was moving when using the ailerons.
@@daysofend I don't thing maintaining a stall is meaningful training, would be like a car simulator replicating crashing into a tree accurately so you can practice that. I guess the cabin slowly moves up right as you're about to stall and then moves down at the beginning of the stall to get you used to that sensation of going weightless and hanging in the seatbelts. The transition is the important part, a pilot should be able to recover at the beginning of the stall. A commercial airliner is fairly hard to stall but once it does it's more or less doomed anyway.
I’m an ex pilot (H) and used to skate vert half pipes. Love how you made that connection and it made me realise something I’d never thought about as an adult. Cheers.
Thanks, really glad you enjoyed!
Motion base simulators are great for lower dynamic aircraft like passenger/cargo jets & bombers, but not great for high dynamic aircraft like fighters. Pilots can be taught that if they pull hard G's long enough, the G-force will eventually reduce - which is NOT correct. Back in the 1980s, we used an air-driven G-seat & G-suit in the simulator that would give the correct cues for a fighter pilot. We also used the visual system to give tunnel vision at very high Gs.
i was wondering how G-force can be reproduced in the simulator since the setup appears to only have ~1g to work with
How do you sustain accelerations higher than 1g? Any system I can think of would saturate pretty quickly and take an insane amount of space.
@@sciencecompliance235 It is not about generating the actual G-force. It is about providing the cues of high-G, namely that at high G's, your G-suit squeezes you, and the higher the G, the harder the squeeze.
It would be elaborate, large, and very very expensive, but I wonder if you could combine a multi-axis pod with a centrifuge. That could theoretically give you all the g you could ever need.
@@CaptainBlackadder75 the problem I see, although I know little about centrifuges, is that say you went from straight and level flight to a 90deg banking turn, the g loading would went from 1ish to say like 6 almost instantaneously. And the moment you leave the turn, the g loading need to go back to 1 very quickly. I’m not sure if centrifuge is capable of this. The second problem I see is that even if the first problem is addressed, the constant acceleration and deceleration it has to handle per flight would be so immense that I’m not sure if the engineering complexity is justified. I guess at the end of the day, the best way to learn fly a jet is to just fly in a jet.
So when i'm in bed, i am actually accelerating forward with 1g.
I'll keep that in mind next time someone calls me lazy ;-)
You’re always in +1g when you’re not moving. Unless you jump or get into a machine or device that alters it. You’re just chilling in +1g 😎
As for the navy pilot… Seems he and every other navy pilot would be very familiar with this phenomenon and it still begs the question… of how he somehow chose to fail…
You're only accelerating, if your velocity changes. If not, then acceleration is 0 and your motion is uniform.
FlyByMax: “If gravity and acceleration are in some sense the same…”
Einstein: “Excuse me? In some sense?”
I didn’t even know we had this simulator… And I’m a student at the faculty of aerospace engineering of the TU Delft haha 😅
This doesn't really explain how a trained navy pilot could decide to ignore his instruments entirely when flying in the dark with cloud cover.
If its truly at takeoff, chances are it all happened in about a second. There is no "decided to ignore", there is simply going on intuition, and in this case, his inner ear intuition overrode his trained IFR intuition.
Believing instruments is really hard when every cell of your body is screaming at you to pull up/down. Somatogravic illusions are one of the leading causes of death in aviation, both private and commercial.
Great comment.
So glad to see one of the best aviation channels I've ever seen back. Excellent video!
Wow, that was truly amazing. Having just recently flown in an A320 commercial sim, seeing this on my feed was perfect timing. I never really felt much motion as I flew the sim in a very realistic manner, but if I go again, I'll have them ramp up the turbulents or crosswind so I can feel more..
Thank you so much for making this clip and how great your narration and presentation is. Top class.
Very kind, thank you so much for your comment :)
When I was a miltary pilot, we had two sims : one like this one, the other was a simple set just put on the ground. No moving parts, just a fake cockpit and some 3D rendering on a 180° screen. You know what, just watching the scenery move while you are simulating the flight gives your brain the sensation that the whole thing is moving. While we were tied to the ground, there was no hydraulic systems, no moving parts or whatever.
Visual senses are really powerful to trick you in believing your're moving while you're not ^^
For me when you dont click read more it says cock and not cockpit 😭😭😭
What an amazing comeback !!!!
Thank you!!
Awesome video once again! Great to see you back.
Great to see you again! I remember you from my very first video, thanks for all the years of support!
I took a free online intro aeronautics course from TU Delft some years back, and it was incredibly fascinating. It did require a fair amount of math.
The simulator is much more complex than I initially thought. Great video showing the engineering difficulty.
I love the detailed explanation. Too many channels give the basic idea and leave out the detail.
Glad you enjoyed!
Best explanation I’ve seen in my 28 year flying career. Well done!
Thank you!
Well explained!!! Without cutting any corners. I tip my hat off to that.
Thanks!
Your videos are also exceptional Hexago ! Hope you will keep them coming too.
Superb Max! Having worked there, it means even a whole lot more!
Thank you so much!
Amazing video as always!!!
Videos like this make me appreciate CZcams even more. Great work!
Thank you!
Excellent explanation and graphics! Best video ever on this topic.
I already knew this stuff, but it's fun to see such a great visual representation of the physics and math behind it.
Amazing Video, animations look super cool!!!
Thanks Fredrik!
Really interesting and surprisingly intuitive. I tend to get slightly nauseous on planes and one thing I do to try and make it better is I focus on my sense of balance and try to visualize the orientation of the plane based on my senses. I noticed a feeling of rotation at the beginning and the end of when the plane rotates, and that's perfectly simulated here with those washout filters!
Outstanding material! Thanks and keep up the good work!
Thank you!
Thanks for the video!
Interesting how those mistakes happen even with HUD information.
I find the somatographic effect so interesting, and the better understanding of it and how it is applied to both sim flight training and the human factors of a number of aircraft crashes (like the F/A-18 catapult crash mentioned in the beginning).
This was very well made, adressing a very specific niche but really intriguing
Thanks!
I was actually thinking about that stuff several times. Thanks for the video :)
I had the opportunity to 'play' in a jet fighter simulator that can flip upside down. I was VERY impressed by the sensations. I have always wondered about how a simulator can fool you into thinking you are climbing. This video was great - thanks.

As a side note - I am a glider pilot - I once climbed into a cloud with an instructor (and only VFR instruments). We wanted to test my ability to sense the g-forces when visual cues are removed. I thought we were flying straight and level, but when we popped out the side of the cloud we were actually in a relatively steep descent with one wing down. Wow what a sensation; the power and importance of the visual horizon.
.
Last year I flew in France. We took off in a valley and I suddenly found myself desperately looking around between the mountains to get a glimpse of the horizon just to orientate myself.
Thanks! Great to hear your experiences.
The one part you missed was braking on the runway, why presumably needs the simulator to tip downwards with a very brief upward movement of the scenery to simulate the nose dip when brakes are applied. Otherwise I'm very happy to say that all this works in exactly the way I was expecting it to. I'm an electronics engineer so instead of washout filters, I would simply say AC coupling so the steady state does not make it through the system. The turnover frequency of the coupling gives the time needed for the system to return to centre after the load is applied.
Yes, there are two independant factors here, what jacks do and what the display does. This example integrates it. Amazing.
I was able to guess every trick while watching, but it's so pleasant to see such amazing content.
Kudos for the clarity of your explanations and the impeccable visuals, this is high quality educational material ❤
I got to fly a B1-B simulator at Dyess AFB about 20 years ago, and when the sim operator relented and turned on the motion base, it got WORLDS easier to control, it just felt right. In the sim we dropped a massive boom on Abilene and then cruised 50 miles north to see the location of the sim op's fishing shack on Lake Stamford. Flying supersonic at 300 feet even if only in a sim is AWESOME.
Great video! Well explained.
Hey Max. Great video!
This channel deserves a lot more subscribers
That was really interesting! Thank you!
Amazing. Amazingly explained. Thanks.
Oi, great video Max!
Excellent explanation and video.
We need a home version of this with VR headsets.
Motion platforms for home sims already exist (of various quality and fidelity). You’re looking at a five figure entry price for something off the shelf with 6 DOF, but as with everything, there’s an active DIY community that will get you there for cheaper (and *a lot* more work and time and maintenance requirements).
DOFReality sells 2DOF for under $2000.
Why does this vid only have 2k views, this needs at least 50k! Great work man
Thanks!

Brilliant video. Thanks for sharing your insights.
Really great presentation! Aircraft maneuvering is generally described with the following terms: Aircraft Movements are dynamic and are Pitch (Elevator), Roll (Aileron) and Yaw (Rudder). Aircraft Attitudes are static and are Banked, Climb, Descent, Cruise and Slip/Skid. Aircraft Movements are in relation to the aircraft axes. Aircraft Attitudes are in relation to the Horizon. The Pilot Pitches the nose up to Climb, down to Descend, level to Cruise. The Pilot Rolls the aircraft into a Banked Attitude to turn. The Pilot uses Rudder and opposite Aileron inputs to Yaw and Roll the aircraft into a Slip Attitude or too much rudder for the amount of aileron to put the aircraft in a Skid Attitude. Slip and Skid are indicated on the Aircraft Turn Coordinator. Attitudes are displayed on the Attitude Indicator (aka Artificial Horizon) and also by looking out the front window at the natural horizon in VFR weather.
Incredible high quality video, well done
Thanks!
Great video max 😉
Thanks ;)
Confirmed a lot of my suspicions. Very interesting and informative.
what a great video and a great facility
In fact the one of the most important discoveries that helped Einstein develop the law of general relativity was the principle of equivalence, which says that gravity is an acceleration, not a force, in such a way that if you subject a person (in a vacuum) ) at an acceleration of 9.8 m/s^2 you will feel the same as if you were on Earth under the effects of gravity
This is amazing… this is literally what I graduated on AT the TU Delft, with the Simona Simulator. Motion cuing fidelity for a B747. Modelling the semi circular canals and the otoliths of the operator. Good times
Great video, really cool!
Thanks a lot!
Thank you! I have been trying to wrap my brain around that translation. You explained it very clearly.
I have a loose project in mind for a racing sim and was wondering how that works. Some of them actually tighten your shoulder belts to add to the feeling of hard braking. (how about pulling on your helmet with about 35 lbs. for turns?)
Many questions answered. Thanks!!
Thanks!
I wasn’t aware that the view on the screen was adjusted and panned alternately to the pods position. Mind blown.
Wow. Really nicely done.
Thank you René! Means a lot!
great video, i always wondered how these things work
Very informative. Enjoyed it
One thing to note about mimicking linear acceleration with tilting the seat in the simulator, it would actually be somewhat noticeable because while the horizontal component of gravity would match the acceleration, the vertical component would be reduced making the seat feel like it is pushing you up less. This method of miming the acceleration could also only simulate up to 1 g of force by only rotating and would feel less and less like what it is mimicking as it approaches that max force.
That's a fair point, although I think the visual part of the illusion would far outweigh this effect. Thanks!
This is true, but just not significant. The losses and gains don't add up to a constant. If you tilt back 10 degrees, you've gained 0.17 G longitudinally (sin 10), but still have 0.985 G vertically (cos 10). No one can feel that loss.
Much more significant, is the complete lack of sustained G in turns. Should be doing 1.15 G in a 30 degree bank, and only feeling 1.00 is definitely annoying, if not outright distracting sometimes.
Amazing video!!
Thank you! That's very kind :)
Thank you for the superb video, together with its lucid explanations. 🤩
In my experience the most realistic part of the sim is straight and level flight through turbulence, or the feel of turbulence with spoilers deployed and the vibrations from hitting stuff with the nose wheel. The biggest inaccuracy is due to the sim’s inability to simulate g forces accurately in the vertical plane.
Great video and explanation. Modern simulation feels just like the aircraft, at least for Jet transports.
Just one additional thought about somatogravic illusion is not only do you lower the nose to compensate for the perception of over pitching, with a takeoff thrust setting, the lowering of the nose further exacerbates the illusion by increasing the acceleration. Unfortunately I knew a couple of people killed by this phenomenon taking off from a dark remote airfield at night in a high powered piston aircraft. This is the typical scenario, dark night, high acceleration.
Any night takeoff, even after 30+ years of flying is still locking onto the attitude indicator, the sensations still make you feel uncomfortable.
it was an awesome video thanks for making it!
Thanks!
Great explanation and well presented.
Great video, thanks! I did some amateur calcs of forces etc for Americas Cup yachts a while back so generally familiar with forces, but the simulation methods used here are awesome! 👍🇦🇺
Omg the Video make so Sense and the end just make this all Even bettttter
Thanks!
Great video - may I suggest a part 2 that focuses on the complexities of the visuals and the collimated display? Having seen it I can tell you this is one of the biggest changes you'll see between professional and nin-professional sims...
To give some context to those unaware, a collimated display allows your eye to focus in the distance - this has to be experienced to fully appreciate but it's the difference between looking at a far away object on a TV screen a couple of feet in front of you and looking at a far away object out the window. It gives depth to the image and increases the immersion considerably. It also reduces parralax error (which, if using TV screens for simulator visuals) would mean the view would only be correct for one of the two cockpit seats, not both. This is not the case with a collimated display because the focal point is so much further away.
Collimated displays are super expensive which is one reason these cost so much. It would be cool to try one of these sims. Or eventually get it relatively affordable to have at home.m
Thanks a lot for this video !
I always wondered how those clearly limited range actuator could give a realistic immersion for pilots that should clearly know the real deal already.
Now I know, the explication is passionating, and it gives an even better and deeper comprehension of the gravitation/acceleration equivalence !
Great work !
Thank you!
Well made video demonstrating and explaining spatial disorientation... Tho you made me upgrade my gaming setup, yet again. 😮💨
Thank you!
Fascinating!
Really interesting. Presumably it's conceivably possible for the pilot to put in a series of inputs that the simulator controller cannot achieve all of them and still have time to 'washout' back to a neutral position allowing 'spare' hydraulic travel... how often does that happen and how does the controller decide what to prioritise?
You are amazing man,by mistake I clicked but I learned a lot
He's back!
The acceleration feeling by tilt will be overcome the instant outside (simulated ) view is removed. In other words someone in a simulator and not watching the screen will correctly feel the tilt of the platform, even to the point of understanding approximately how much tilt is in effect.
I played VTOL VR and the visual cues alone can trick you into feeling you are actually flying. Can't imagine how coupling that with an actual simulator that throws your body around.
Can it simulate the force of the seat pushing the pilot into the controls?
Good question! Yes, the platform can pitch down to give the feeling of deceleration in level flight (like braking in a car). In this case, the straps/friction of the seat will exert a force that pulls you backwards instead of forwards. Thanks!
An interesting watch, but I have to say much of this was figured out even before I started working at Singer Link Miles back in the 1980s. I think what's really improved since then isn't the kinematics but the vision systems. The computer just for that took up an entire room full of 19" racks.
Super interesting! If only I wasn't damaged by stress I might want to work in this field...
Very very interesting. I would love the same kind of breakdown but for helicopter sim. Thanks again. This one was gold. 🏆
Is it possible to simulate Gs in the simulator - like in a tight turn? Great video with informative and easy to understand visuals by the way.
YOOOOO MAX IS BACK!
Fascinating stuff
This video very well communicates why I pretty much HATE the motion platform (Yaw2) that I got, because all it seems to do is match the orientation in the sim, not the FORCES.
I noticed how simulators used to work and figured this problem had to exist. Its good that we're coming up with solutions, may it help our pilots keep the skies safe ✌
I've seen about a dozen of these simulators at British Airways' massive simulation hall. That was an amazing day
Very interesting. I have to admit I had not thought about this concept very deeply but it all makes good sense. I wonder though in a roll for example, in order to zero the force out the simulator needs to return from the roll position to level, but what prevents that roll back to level applying an unrealistic force to the pilot? In the real world when entering a roll, the forces are the initial roll force in that direction then neutral assuming a properly coordinated turn. But the simulator has no alternative but to apply roll in that direction, then roll in the opposite direction then neutral. I assume it must do it in such a subtle way that the unwanted effect is minimal.
This is an AMAZING question!! You’re absolutely right, when the simulator ‘washes out’ the roll back to neutral, it does this far slower than the initial excitement. That way your vestibular system only senses the initial impulse, not the returning to neutral. You can see this very clearly at 6:40 on the right in the shape of the curve (very steep at first, then smooths out). Great comment.
Excellent explanation. Although I was hoping to learn what causes the discomfort during taxing in the sim. Its pretty weird they can trick your brain with every motion in flight. But when on the ground in many sims something just doesnt add up and causes nausea.
I love this! Thanks
Thank you!
This is awesome - I wondered how CAE Simulators mimick the feelings and this seems to show a lot of similarities :)
Thank you for this great video! TU-Delft is doing research with our compact 6DOF motion simulator EDGE 6D to bring SIMONA even closer to everybody's home! Best regards, Team Gforcefactory
This is a great video. Was thinking a lot about this kind of trickery in terms of VR motion sickness cure. It could be a platform that simulates acceleration by simple tilting
