Who wants Blade Element Theory Aerodynamics?

Hey guys,

I’d like to know if you guys agree that **a different aerodynamics model would be appreciated **
throughout the community. Right now, the athmosphere-simulation (at least, coming from
somebody with 2800 hours in X-Plane) gives the aircraft too much lift in high altitudes.

I could easily reach FL390 in the A320 or the 747 while being FULLY LOADED and
thats simply not realistic. Those aircraft cruise at FL310-360 max. with a high payload
and as they get lighter with less fuel, they increase the CRZ ALT step by step, because
they’re simply too heavy to economically sustain CRZ LVL in those heights.

Also, ground effect simply isn’t a thing right now. Also, STALLS are simply unrealistic,
in many aircraft, they just don’t happen. Heavy rudder usage also feels weird, theres lots
of room for improvement.

Please feel free to discuss below on wether or not this should be implemented as an OPTION
to choose between the current flight model and Blade Element Theory.

You mean like having a setting that says “Modern” which is the default?

Did you know that X-Plane has been around forever and still adding new features to their flight model to make it realistic? Yeah, it would be nice if MSFS BET was as good and bug free as X-Planes right now but that is simply unrealistic. A small company can’t catch up 15 years of development in a 1.0 release.

Anyway, you are talking about two different things. You are largly mixing default aircraft performance with flight physics as if tweaking physics formulas is the way to get an aircraft to fly properly. That would be an odd thing to do.

2,800 hours in X-Plane means little, especially to someone that fly’s for real. It makes an assumption that:

  1. X-Plane is completely realistic. It is good, but that isn’t true.
  2. That you know how to compare aircraft properly. Any real pilot or decent simmer will know that aircraft performance varies with model, wear and tear, equipment loaded, etc, and that they can perform differently in different atmospheric conditions including weather.
  3. That you are probably comparing a payware aircraft that has had many revisions in X-Plane with a default aircraft in a new sim.
  4. The current issues aren’t because of bugs. They most definitely are.

brother, there is NO way of comparing planes and how they feel. The planes we have are all broken, performances are not correct, weather and winds and everything are constantly been fixed and corrected. There is no way of comparing them yet.

If you want blade element theory why not just stick with x-plane?

I fly GA aircraft IRL and neither sim flies like the real aircraft anyway. Both do a decent enough job of it for simulation. Both platforms will continue to get updates so I’m sure they’ll both get improvements over time.

Just 2 hours ago you posted this:

lots of people including me use a gamepad and I with one modifier button (L1 on my PS4 controller)
theres everything you need for flying, works like a charm and saves desk space!

Pardon me if I don’t take your desire for realism too seriously :joy:

No… please no. If you like Blade Element use X-Plane. I have tried X-Plane off and on (mostly off) since the days of running it on a Mac. It feels like balancing a spinning plate on a chopstick.

Maybe good for helicopters? :wink:

Can I cast a negative note? As in minus one? :smiley:

I get your points guys, this is why I’ve asked a question in the first place instead of trying to convince anybody with an assumption. I’m using the PS4 controller because a) it works, b) the result is the same as with a stick or yoke - it just saves desk space and is quick / easy to use, so don’t judge me by that.

I’m not expecting a 1.0 sim to beat 15 or any number of years from Ausins experience with his flight model, neither am I saying one is better or worse than the other.

I’ve just compiled my personal experience between both sims and asked if (and optionally why)
you guys would wish for a new flight model or a different one.

If anybody needs an opinion from IRL pilots, there are quite a few reporting back on that topic in YouTube and so far, most of what I stated in the thread post above, is similar to what most of those guys said along my research. Thats not a gut feeling, I’ve actually looked at different sources and opinions around the web before posting.

Say what you wanna say but keep it friendly, this is a discussion, not a fight…

No fighting no biting (what book was that from?) :slight_smile:

I’ve been flying single engine GA aircraft since 1978, both Pipers and Cessnas. (And a Citabria on occasion back in the day.) Flight Simulators do an admirable job at simulating the dynamics of powered flight. They have gotten better and better as hardware has improved as well.

The flight model in X-Plane is my least favorite, and I’ve felt that way for years. Maybe I should give it another go, just for fun and for the sake of learning. Back when I last had X-Plane running (six years ago?) I nearly always opted to “fly” in FSX instead. I know X-Plane has quite a following, and has become quite a bit more refined over the years.

I suppose it is a Ford vs. Chevy or a Piper vs. Cessna type debate. For me, it comes down to what I feel most comfortable with. The new Flight Sim feels pretty good. But it is, after all, still a simulation.

a) agreed

b) I definitely disagree. I’m using a T16000M on my PC, a gamepad on my laptop and regardless of the sensitivity settings, with the short gamepad sticks, precise and/or small control inputs are very difficult to achieve.

A joystick makes aircraft control noticeable easier and more realistic IMO.

The T16000M is - pardon the pun - a joy to use. It is a far departure from older technology. I can’t imagine “flying” with anything but a good joystick, and the T16000M is a really good joystick. The HOTAS that comes as a “bundle” is not as good, but I’d still give it a “B-” if for no other reason than the plethora of programmable buttons.

Sorry… didn’t mean to get off-topic here…

If I have to compare X-plane and MSFS based on the default 172 (analog) in ISA conditions I’d say the X-plane one feels a bit (only a bit) more realistic, especially on the ground roll. Flying the two isn’t that much difference, but again slightly in favor of X-plane.

Having said that: the visuals and weather of MSFS and the fact I don’t have to download 60GB of orthoXP tiles make up the difference by a whole lot :slight_smile:

(IMHO)

nah, I don’t want an extra aero model, I just want some improvements to the current one.
This is a next gen sim, using next gen technology. It just needs some iterations (like like X-plane has had over the years).

Before I add a comment on having the blade element theory aerodynamics has an option in FS2020rc2 or later version, I would like to know if that is now possible because Laminar Research is up for sale. Did I miss some news?
I can already have it as an option on my PC if I reinstall x-plane.
:innocent:

I can perfectly manage your b) point. Sensitivity to -75% + I’m just used to it.
Its all a matter of practise.

I was under the impression this was already used.

TBH I haven’t noticed much difference between flying in X-Plane and MSFS with GA, the atmospheric effects certainly feel better in MSFS.

Where did you get that text from? I haven’t seen any info on exactly how MFS models the aerodynamics but I’m I didn’t think it uses blade element theory, I thought that was mentioned early on by the dev team that it doesn’t?

Here it mentions that MFS doesn’t use BET - How X-Plane Works | X-Plane

If you haven’t tried XP for 6 years or so I would try it again since from just a couple of years ago the FM has changed a lot.

I would have said that this person has misunderstood what BET is but since he’s got letters after his name and he’s writing for the RAS he probably knows what he’s talking about, so maybe he has just misunderstood how MS are actually modelling things? Because if MS/Asobo and LR don’t think it’s BET I would love to know what he thinks makes it so.
