Hi everyone, Laura from Infinite Flight here, chiming in since we're mentioned :) Our flight model is in constant evolution. We work in iterations, adding new bits every release depending on what we're working on. I have done some experiments with better prop simulation that handled P-Factor and other propeller related forces that impact the aircraft in different ways. I just haven't had time to finish it. This year, we implemented prop wash when we worked on the XCub because it has a significant impact on the flight model. It affects all the surfaces downstream of the propeller. Another one we added this year is the fuselage shadowing the wings during crosswind when the plane is decrabbed. About the question asked at 8:00, we don't simplify our flight model at all, let alone intentionally. It's quite the contrary. It actually is harder to simplify things compared to letting them act according to what the physics math dictates. We're bound by the same equations Austin has mentioned here, taking into account air density, gravity, wind, turbulence, moments of inertia, etc... The only difference right now is how far we decide to simulate things based on development priorities and performance constraints. Basically, if anything is missing, we're probably already working on it and it'll be available in a future version. Having said that, I'll try to spend some time on this so we can spread the educational workload between Infinite Flight and Laminar support teams ;-) Cheers!
This is how things should be handled. Right up front, with real answers. Nobody getting their tail in a twist. Stated the facts, answered the question directly and the sim world is better for it. Good on both of you.
@@Christian-cb9jr I'm not sure what this has to do with the items discussed here... but for the record, Google could shutdown tomorrow we would still be running... Specifically because we're not using Google Maps. Our scenery service is all in-house, the servers, delivery, processing of imagery. Cheers!
I appreciate when Austin does some basic flight mechanics, etc. It actually adds to the appeal of X-plane. He is willing to talk about the sim, talk about flight, talk about the company, talk about the PC and peripherals. He and Michael are actually interested and willing to work to do what they can to make sure you have the best understanding of flight and getting enjoyment from the sim on your computer or tablet. That is what they do. Sometimes it's not as fast as we would like due to budget or man power, but they are always working towards those goals.
hey guys, totally spot on here. although I'm a private pilot, and I do feel like the effect is a bit stronger in x-plane than in real life. I have to push the pedals a lot further to the right to compensate for torque steer on take-off, than I do in a real plane, which only needs a small amount of pedal pressure...
I hope that I am wrong, but I have a feeling that the people who need to watch this video probably won’t, although full marks for trying to get the message out.
Exactly.. anyone watching this video already knew at a minimum that cessnas yaw on takeoff power (but maybe not why) and the rest already knew why. So the moral is you got a 1 star review because u opened your sim to a new audience (a good thing) but assumed they were as educated as your existing audience. Add a popup that says 'protip: real single prop airplanes tend to yaw on takeoff power. Add opposite rudder to compensate.' Make the popup come up every time a cessna etc is chosen with a (dont show this again) checkbox on it. A tutorial is not a bad thing either(desktop has them but unsure if mobile does) and iirc the tutorial talks about this. But assuming mobile users want to get going quicker, the popup is the best bet
I actually didn't know about the fact that the cessna kept yawing to the left, but I tried to think from another perspective and searched if it was a game error or real life, and thanks to this video I know more, and one day I'd like to become a pilot or an aerospace engineer so it was very useful to know, I'm 14
As a retired Army Apache Test Pilot, your explanation us spot on, but remember at times you will get those that cannot understand, you can use my fallback explanation, PFM, pure f'ing magic!
Besides the great teaching Austin is doing on aerodynamics I really DO like his implemented soundcard: wooooosh schuuuummmm ... :-D X-Plane is still the best!
You just explained PERFECTLY why every single time I tried to take off in DCS WORLD in the Mustang I spun left and crashed. Even with the rudder trimmed I didn’t realize I needed to take off at partial power. I was so used to the F16, I go to 100% on Takeoff.
For people flying X Plane who don't have a clue on how to actually fly an aircraft. This might help you guys. What Austin is telling you is it's pretty simple. The reason single engine propeller aircraft pull to the left in real world aircraft is because more thrust is generated as a result of the propeller blade falling. downwards on the right hand side than the opposite blade produces traveling upwards on the left hand side producing less thrust on the left than on the right. This effect is known as or is called "P-Factor" and it happens with all single engine propeller aircraft types. Austin has therefore coded/programmed the P-Factor effect into X Plane for a more realistic piloting experience. The standard procedure in order to correct the "P-Factor" effect is to counteract this effect by simply applying the correct amount of right rudder in order to counteract this effect and to keep the aircraft straight. It's like ridding a bicycle and once you understand why and how to deal with the issue it's simple. Lol 😂
Some can't get out of the GAMING scenario. Try adding weather to it as well...haha. I'm glad you are explaining it. And by the way. X Plane will always have me as a customer.
I find it amazing some folks would give X-Plane a low ranking because it simulates actual aerodynamics and doesn't model aircraft like a "flying truck" as practically every other mass market flight simulator does.
Hey there everyone In simple terms The air never flows in a straight line and it hits the vertical stabilizer it hits it with enough force to push it a little bit (to the right) Which makes the front go to the left (At least that's how my flight instructor explained it)
One of the reasons I bought X-Plane 10 and 11 was to experience the wind. Over time I got the point of having the wind with me. It sits there as part of the plans like a good friend when really understanding it.
I only downloaded and it was pulling to the left before I googled it. Might be an idea to say this on your flight school so it’s clear and you’ll avoid the 1 star reviews. It does make the initial take off and maintaining a steady climb awkward….so if you are not aware of this, it appears as crap controls even though your simulating real flight characteristics. Good explanation video tho!! I’m heading back try it again!!
Thank you so much for this explanation! I recently tried playing a flight "game" on my iPad and I naturally compensated during takeoff by rotating to the right and ended up going off the runway multiple times because they were not properly simulating real world forces. Thank you for the explanation and for incorporating realism into even your iOS version.
Thanks for this great video. The cause of this phenomenon is very similar to why boats with single inboard motors have prop walk in reverse. That is, the propeller creates a swirl of water which deflects off the keel in an asymmetrical manner. As I learn more about flying, I've noticed there is a lot of overlap with the physics of sailing.
Cool, thats why I am still struggling during take-off from LUKLA with my Thranda Pilatus Porter PC-6 witrh its BIG horizontal stab and rudder. Even with tailwheel locked, when the tail comes up I am in trouble keeping it on the runway, but I like this realism. I have to practice until I can do it. Love it!
Dear Austin, Yes, i am a big X-Plane fan and follower of your great interest in applying real aerodynamic forces on the simulator. Yes, i totally agree with your excellent physical explanations.. (But) since the new betas with improved flight models, my cessna totally goes to the left.. Dont understand me wrong. Not a little bit, just literally leaving the runway, and with my right rudder strongly applied, i cannot maintain the centre line. (I do it at low speed when taxing). I am also a SEP PPL-A and in the few C150, C152 or C172 that i flew in real life, i eventually press the right rudder gently, never at his maximum .. and (hopefully), i never left the runway during taking off.. I dont know why and how but in the beta that i ran, the tendency is exaggerated and unfortunately not realistic anymore
P-factor, also known as asymmetric blade effect and asymmetric disc effect, is an aerodynamic phenomenon experienced by a moving propeller, that is responsible for the asymmetrical relocation of the propeller's center of thrust when an aircraft is at a high angle of attack.
On top of pulling to the left i think it might be useful to mention on jets once on the runway you might want to turn off nose wheel turning if your aircraft does not do it automatically. I have had an issue with that for weeks before i figured out to turn that off. Mostly fly p3d and dont have that issue or if i do i don't notice it much.
Great video, it's always good to know the reason behind how planes handle in X-Plane 11 (and mobile)! You should put this up on the app store so that people know why it happens before writing the bad reviews :P - I look forward to seeing what X-Plane will offer in the next year and hope to see you prove me wrong about that flight sim from Microsoft!
Even though I know exactly how it works I still enjoyed this video. Austin is fucking awesome and funny as fuck. Love how he explains it. Been flying xplane since v9. Hands down the best sim ever made. Nothing else has ever come close at all. Keep doing what you guys are doing, you are all amazing.
Thank you Austin. Nobody else, and I mean NOBODY, adds the angle of attack detail to the lift assimetry explanation. Which bugs me because you need a vector of relative motion to cause it. If it's stationary there is no effect
yeah, a real aircraft does that, like a Baron 58. But in a C152 / 172 you almost don't see that happening. The taxi/takeoff behaviour of those aircrafts on XP11 it's just ridiculous!
This effect is much more prevalent in single engine airplanes than in multi engines like the baron. Because of the slipstream against the vertical stabilizer. And have you ever flown a single engine airplane like the 172 in real life? I highly doubt that. I have, and I can confirm that left tendency totally.
@@markusthl I've flown the Baron 58, 152 (mostly) and 172. Again: the taxi and takeoff behaviour are not close to the real life. Every time while're taxing, you have to give a right rudder to compensate that unreal behaviour.
@@Coloursoundm what you are talking about could also be the wind-vaning effect of the planes in X-Plane when the wind is blowing into the vertical stabilizer. That effect really is unrealistically simulated.
And the low speed taxi turn is another thing that iritates me on XP. The aircraft simply stops while turning, you have to almost set full power to win the inertia, just to make a simply 75-90° turn on ground. And you know that in real life it's not like that, even close.
Good explanation of P-factor and corkscrew effects, etc., to explain why aircraft pull to the left. However, in X-Plane it is still exaggerated making it hard to maintain centre-line precision. Here's a suggestion, why not provide an option to switch on/off those forces completely so people can just have the fun of flying in a virtual world. Call it "EASY MODE" or whatever but there are times when that level of realism just isn't required.
X-plane 11 already wipes the floor due to developments with Vulkan. I'd like to see MSFS have that good of performance and not just focus on DirectX/OpenGL
@@VincentW2 The flight model for 2020 is going to suck. Exaggerated stalls, no ability to author your own planes, probably a crappy or nonexistent SDK because well Microsoft. The developers will be fired or transferred after the bean counters realize they are more useful in cloud or analytics than some fart in the wind product.
Love your videos, ty. Btw, interesting demonstration... but, wouldn’t the Elevator (both?) demonstrate axil flow interference to rudder moment reaction?
Hey!!!. Can you design a way use headteacking mode with panoramic views (no cockpit)and 2D panels for separate monitor and this eliminate the need for air manager.
Very good video to explain why I am suffering to keep the plane on the runway; but one question : where did this pulling force go when we are in the air ?
As the speed builds, you get more rudder authority from the air streaming straight back due to the forward speed of the plane!! AAAAAANNNND, as the plane speeds up, the prop is grabbing many MORE pounds of air per second as it races forwards into fresh air, so each pound of air is spun a lot LESS, because there are so MANY pounds per second being grabbed!
Austin, great explanation! What I always wonder in X-Plane, is whether the wind-vaning effect of the vertical stabilizer is really realistic? When I flew single engine airplanes in real life and the wind was blowing into the stabilizer, I never noticed that big yawing tendencies of the plane like in X-Plane.
Ah, the day when I first got XP10 and was freaking out to as why my planes were pulling left during takeoff! I was 10 years old at the time which shows the mentality of Infinite Flight users lmao
Any news on updated ATC? Also, can you guys implement a way to change aircraft in mid flight? It is great that you are teaching the younger flight sim enthusiasts basic aerodynamics.
What? Real airplanes pull to the left on takeoff? Hell no, I’ve got 125 hours in the PA-28-161 Warrior III, and not once have I ever had it pull to the left on me when I apply full power, or if it does it’s nothing like X-plane meaning the effect of the plane going left in X-plane is way less that what an actual airplane does, I’ve seen it in X-plane 10 and the effect is way less in real life
At your helicopter example you said, the thing is pull up because of the gyroscopic force. But why you doesn't told it on your 3rd example? So, if I understood it correctly then it should pitch up, because the force goes 90° and effects on the bottom side. I guess I have done a mistake...but where...?
@@yetidynamics Ah, I thought the gyroscopic effect effects ever time exactly 90° Mhhh... Does it mean, at a helicopter it effects not everytime 90° as well?
@@alexanderbrandau5456 hi, I think there is a misunderstanding. there are Two effects going on, in both propeller airplanes, and helicopters, those two effects are the Gyroscopic effect, AND the asymmetrical thrust/lift effect. However in a propeller aircraft the gyroscopic effect is not that significant compared to the asymmetrical thrust effect. The torque caused by the Gyroscopic (effect) isn't going to pitch the aircraft upwards nearly so much as the asymmetrical thrust will yaw the plane to the left.
I discussed this question last month with Austin and my friends... I got to this conclusion that : in 3rd example the disk is not rotating and the extra lift is created internally and disk in not rotating as a result of that force so no gyro effect happens... but in 2nd example as a result of that extra lift the disk of blade rotates...(in this kind of heli the disk of blades can rotate.... so as a result of that extra lift disk can rotate so the effect of that force will be seen 90 degrees after the lift creation spot... I am still not 100% sure abt my conclusion for 2nd example....If anyone has a better definition please reply ...
There is pulling to the left and there is turning left. It's way exaggerated in X plane. I love X plane but the pull is over exaggerated and can be annoying
Sorry guys, but X Plane mobile app gamers dont care. They dont need complex flight models or other real world aviation simulation. Mobile gamers want simplicity, easyness, enjoyment and not complicated stuff. The users who enjoy complicated simulation use PC and have a aviation interest. How´s that for a trivia?! Wonder why you get 1 star reviews ..... it´s not rocket-science.
Boy I hate to say this... because I can recognize Austin's mannerisms as enthusiasm. But I can also see how it can come off, to some if not many, as utterly flip dickishness. Please tone this down. Please. It's really counterproductive for Laminar. Some will see it as assholery. Others will see it as totally amateur. Either way, it's not the image you want. It's far better to give presentations like this some aforethought. And do it right.. not with a couple of yutzes riffing. This is *precisely* why you made the right choice to yank your Q-A recently. Rightly so. This tone simply does not help.
Laura Laban your response was very well crafted and thought out. Kudos to you. I didn’t mean anything big by my comment, just making a joke! Keep on developing. The more competition the better in this market, even though different simulators serve different target audiences.
Austin: I do wish you wouldn't divert precious dev resource into mobiles. I'm sure that serious simmers and pilots are not using them - and you yourself have described x-plane as "not a game but an engineering tool". With the new MS sim on the horizon you should focus on the desktop as that's where the battle will be. We nbeed Vulkan!
X-Plane11 is excellent, Austin and Michael are the best for these tutorials.

Well xplaned .... 😂 ill get my coat
Great video. One thing I also want to ask is when you put the flaps down in X-Plane mobile why does the nose go up?
I can't get enough of these videos.
So meaning when adjusting the wind to the side of the tile will it make the plane more stable.
Just want to make things harder lol
Hope you do a review of fs2020 when they come
Ure kidding right?

Hell no, I’ve got 125 hours in the PA-28-161 Warrior III, and not once have I ever had it pull to the left on me when I apply full power, or if it does it’s nothing like X-plane meaning the effect of the plane going left in X-plane is way less that what an actual airplane does, I’ve seen it in X-plane 10 and the effect is way less in real life
Grave concerns for XP. It's gonna end in a fireball.
So if the tail was below the airframe, it would pull to the right instead? Interesting. So have a tail above and below. Sorted. 😉
At your helicopter example you said, the thing is pull up because of the gyroscopic force. But why you doesn't told it on your 3rd example?
So, if I understood it correctly then it should pitch up, because the force goes 90° and effects on the bottom side.
I guess I have done a mistake...but where...?
in the case of the plane the Thrust effect is more overwhelming than the gyroscopic effect
@@yetidynamics Ah, I thought the gyroscopic effect effects ever time exactly 90°
Mhhh...
Does it mean, at a helicopter it effects not everytime 90° as well?
@@alexanderbrandau5456 hi, I think there is a misunderstanding. there are Two effects going on, in both propeller airplanes, and helicopters, those two effects are the Gyroscopic effect, AND the asymmetrical thrust/lift effect. However in a propeller aircraft the gyroscopic effect is not that significant compared to the asymmetrical thrust effect. The torque caused by the Gyroscopic (effect) isn't going to pitch the aircraft upwards nearly so much as the asymmetrical thrust will yaw the plane to the left.
@@yetidynamics Ahhhh
No I understand👍
Thanx for your explanation
I discussed this question last month with Austin and my friends... I got to this conclusion that :
in 3rd example the disk is not rotating and the extra lift is created internally and disk in not rotating as a result of that force so no gyro effect happens...
but in 2nd example as a result of that extra lift the disk of blade rotates...(in this kind of heli the disk of blades can rotate.... so as a result of that extra lift disk can rotate so the effect of that force will be seen 90 degrees after the lift creation spot...
I am still not 100% sure abt my conclusion for 2nd example....If anyone has a better definition please reply ...
Love the explanation BUT, how do you takeoff without this effect?
Right rudder.
Merry Christmas
There is pulling to the left and there is turning left. It's way exaggerated in X plane. I love X plane but the pull is over exaggerated and can be annoying
Link this vid to all bad reviews!
Please fix the xplane desktop engine before it's too late
hahahahahah this man is awesome
One of first things they teach you when preparing PPL theoretical exam...
In other words we are stupid lol
Just put some planes doing it wile filming, so some ppl would absorv it
Sorry guys, but X Plane mobile app gamers dont care. They dont need complex flight models or other real world aviation simulation. Mobile gamers want simplicity, easyness, enjoyment and not complicated stuff. The users who enjoy complicated simulation use PC and have a aviation interest. How´s that for a trivia?! Wonder why you get 1 star reviews ..... it´s not rocket-science.
6 stars
I left a one star review because the physics model doesn't match GTA V.
Boy I hate to say this... because I can recognize Austin's mannerisms as enthusiasm. But I can also see how it can come off, to some if not many, as utterly flip dickishness. Please tone this down. Please. It's really counterproductive for Laminar. Some will see it as assholery. Others will see it as totally amateur. Either way, it's not the image you want.
It's far better to give presentations like this some aforethought. And do it right.. not with a couple of yutzes riffing. This is *precisely* why you made the right choice to yank your Q-A recently. Rightly so. This tone simply does not help.
Nice.
Austin, please quit nerding on trivials in flight dynamics and fix FPS issues.
Thanks
That is already a top priority. Beta hopefully soon.
Marco ten Haaf Please stop your annoying whataboutism crying and get a proper hardware. Thanks.
@@mowax74 Oops, I forgot to get proper hardware. Yeah, that's the problem. Thanks for pointing it out.
Or not!!
hi !!!!!!!!!!!!!!!!!!!!
I hate to say IPhone users are .... Well let's leave that there...
If you don’t wanna fly with realism and real effects, go to Microsoft flight simulator! Boom!
Another upset fan boy lol, and I don't even like FSX.
I really hope someone from infinite flight watches this lol!
We did watch ;) Just replied to this video.
Laura Laban your response was very well crafted and thought out. Kudos to you. I didn’t mean anything big by my comment, just making a joke! Keep on developing. The more competition the better in this market, even though different simulators serve different target audiences.
Austin: I do wish you wouldn't divert precious dev resource into mobiles. I'm sure that serious simmers and pilots are not using them - and you yourself have described x-plane as "not a game but an engineering tool". With the new MS sim on the horizon you should focus on the desktop as that's where the battle will be. We nbeed Vulkan!
