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.
If you're interested in using SIMONA for research, check out the Control and Simulation MSc program at TU Delft: www.tudelft.nl/onderwijs/ople...

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

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)

@mitchellh5869 2 ай бұрын

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.

@severoon 2 ай бұрын

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.

@@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.

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.

@kinfongyeung5400 3 ай бұрын

@@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.

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 ^^

I have the same brain as the engineers who built it. I understand black box algorithms, I understand the inputs and outputs of the vestibular system. I understand the math of inpulses and dampening filters. I can figure it out by looking at the obect, examining its inputs and outputs, and making a good guess about it. That comes from putting in the time to learn and think about it, not intelligence, Ive been doing this for a decade, the same 10,000 that Malcolm Gladwell says it takes to become an expert. If you are genuine in your question, I would say that its important to recognize the process which leads you to "its intuitive". Acknowledge that we all learn about forces and accellerations and dampening differential equations in college. We all deconstruct the things around us to figure out how they work, we all have curated a brain that excells at considering the factors involved in a problem and solving them. Thats engineering, and I studied it in college, and have been doing it for half a decade professionally and the same as a hobby/fascination. Its not bragging to have your work be somewhat intuitive.

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.

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.

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

@Axel_Andersen 10 күн бұрын

I thought for decades that it is true that acceleration is indistinguishable from gravity. I only recently understood that this is only true for point observer. If you have observations from two or more locations then you can tell the difference because gravity changes as function of distance and for rigid body the acceleration is all the same everywhere in that rigid body.

This helped me to imagine what flying in space with a rocket pack could feel like. In space, you'll feel like you're in constant freefall, because no forces will be acting on you.

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.

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

Well made video demonstrating and explaining spatial disorientation... Tho you made me upgrade my gaming setup, yet again. 😮‍💨

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

Thank you, you answered a question I had ever since I was on a virtual reality roller coaster as a child 😅

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.

when you used to fly VFR for a long time, then took the instrument course, the first time you find yourself flying at night with only instrument to guide you is scary as hell.

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.

Do the 6DoF platforms for PC gaming take under consideration that? Do these have washout filters? Thanks for the video.

I wasn’t aware that the view on the screen was adjusted and panned alternately to the pods position. Mind blown.

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

I've seen about a dozen of these simulators at British Airways' massive simulation hall. That was an amazing day

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.

I was blown away as a kid when I felt the acceleration in a simulator..I asked my dad how it worked and he said they blow air in your face while tipping you back, but you're still "looking forward" ... genuis
