Maybe im reading this wrong but what are you trying to say here?

I think @Stoopy is saying that since MScenery have already released a Boeing B-52 that they have enough experience to take a crack at producing a correct 777.

All while his tongue is firmly in cheek.

Perhaps something intermittent in coding is creating those problems. I don't know, but for sure, something is amiss. 

It's likely the way the plane handles live weather. If you fly it in the clear weather preset, it is very stable. Using live weather, any sort of wind or gust seems to destabilize the plane.

I assume this is mostly an autothrottle issue. Blackbox did a stream recently where he hand flew the approach with autothrottle disengaged with a 12 knot cross wind and was happy with how the plane felt. But flying it with the AT engaged, like Boeing recommends, feels very strange in the sim.

ohh gotcha gotcha

 

Is it just me, or does the 777 (in my case, the F) do a bit of "thrust hunting" when slowing down to set speeds when on descent and final approach?

No, it's not you; the AT is not great at all.

I do not recall the P3D version of the 777F/LR suffering from the same problem, although I do remember that it struggled to flare properly at times.

I agree with you that there is also an issue regarding how the PMDG handles WX, which adds to the problem. Unfortunately, it's not just that; my testing was done without WX. After noticing how unrealistic it behaves in updrafts, downdrafts, and crosswinds exceeding 25 KTS, I gave up. 

Initially, Boeing recommended that while hand-flying with AT off, after they did the software update, the AT worked flawlessly, anticipating well ahead of time and adjusting very smoothly without causing any pitch changes, similar to how it does in the 744 and 748. 

For some reason, they don't get it; it must be someone’s interpretation with poor coding that is messing everything up, and they’re reluctant to acknowledge it. Additionally, there’s another issue: books aren’t what they used to be. Pilots with limited hours in the airplane aren’t quite up to speed, and those not exposed to the real airplane, who don’t understand the systems, begin to spread their own incorrect interpretations.

We brought this to their attention since P3D, MSFS2020, and now we have discovered the same issue with MSFS2024.

Maybe. I don't remember well what sample rate uses the actual aircraft for the FBW, but it should be in the order of kHz (yes, I mean tens of thousands of times per second). Please someone correct me if I'm wrong.

OTOH, in the sim, the displays are refreshed barely at 15-30 Hz. If lucky, it can get up to 120 or 144 Hz, but that is still too low. I guess the FBW sample rate is similar. May that explain why it reacts that way?

I don't know. Programming is beyond my knowledge. I also notice some delay in the elevator input/reaction, which none of their a/c have, also in real life, the airplane flight controls movement is there without any delay. Anyhow, as soon as they were quick to take our money, they should figure this one out, or return the money to the customer. 

PMDG, ENOUGH IS ENOUGH WITH SELLING UNFINISHED/BROKEN PRODUCTS AND EXPECTING TO BE PAID FOR THEM.

Has been wrong since it was released for FSX...

Is plain wrong in the FS 2020 773...

Not going to spend my good money on it just to find out it continues to be wrong as ever 😕

I had to quote this post of mine to amend it because, after having watched a few videos, and one in particular where A330 Driver talks about how the FBW is implemented already in the PMDG 773 released for FS 2020 I have to admit that even with it's limitations it looks better than what it was in P3D.

I'm referring to this particular video: The 777 Fly By Wire Explained | Real Airline Pilot

 

I would not expect this to get fixed. This unrealistic behavior is in every single 777 they have ever released. It is pretty clear at this point that they simply do not have the ability to develop a 777 that can at least somewhat match the real plane in terms of handling.

What we need is another developer to make a 777.

Is anyone using any of the 777s with SU3 beta? Does the thing work, namely the 777-200ER which is the only one i really want.

Thanks.

Apparently the 777s are generally having CTDs in SU3 beta right now.

The real life testing of the engines is done using a Precision Time Protocol over the network in the engine test bed with accuracy expected to be between Nano and Picosecond...  Crazy.

Actually, you are not fully wrong 🙂 Alex Bashkatov, who is now lead developer for 777, already developed 777 and 747 back in 2002-2003 for Phoenix Simulations (FS2000-FS2004).

Yes, I'm that old 🙂 

That explains a lot. The PSS 777 flew terribly. And when you have beta testers like Dan Downs saying it flies great, well, it’s never going to get better, just like the sounds which are still terrible (I’m referring to the non engine sounds which were already updated per their posts).
