  1. Thank you for your dissertation about the Mach number and the IAS, but if you my posts carefully my doubt is regarding the engine envelope (see power variation with altitude), and how the Ifly sim plane V/S is varying close to the max altitude. The IFly is just the one that behaves in that way, and Stearmandriver told me that the other devs/airplanes are wrong and that I'm a "little too accustomed sim aircraft". In my opinion Ifly is wrong on this aspect, not the other devs.
  2. Maybe we are talking about different things, fortunately the dev gave me less elusive answers than yours and they will give a look on this "strange" V/S behavior.
  3. I'm not satisfied with your explanation because I think that you are not assuming the lack of power of the engines at higher altitudes, the mach number you are talking about is varying with the altitude: more altitude, more higher the mach number because the air density, temperature, etc. But this has nothing to do with the vertical speed, where you can see a very strange climbing jump where the engines are struggling to push the mass of a full loaded airplane when closing to the max planned altitude. Secondly, but not least important, this Ifly 737 is just the only one sim airplane behaving in this way, maybe the other devs are all wildly wrong on this aspect?
  4. I'm accustomed to sim aircraft because I'm just an old engineer and not a real pilot, so I can just observe the sim aircrafts and the YT real ones (if lucky). My question is regarding the engine envelope exclusively: all the jet engines drop their power with altitude, I can't understand how can a liner at full load and near to the max altitude with its engines breathing almost 40% less is "jumping" from 1.000 ft/min to 1600 ft/min and more.
  5. This B737max has a very good potential, but I'm 70% satisfied because the flight and the engine modeling. It's very good at ils autoland, I don't like the wobbling in turbulence, it seems a glider, not a liner flying at 250/280kts. The engine envelope has something wrong as I saw in FS20: after 30.000ft, normally a turbofan jet engine decrease the power progressively as you can see with all other simulated airplanes, but this B737max is going from a normal 1200ft/min to about 1600/1800 ft/min at fl340 and above. I think that 2 normal turbofan engines pushing a full loaded liner doesn't have all that power near the max altitude/ceiling. The devs told me that this is due to the passage to mach, but I think that this has not nothing to do with the engine envelope, where near at max altitude the power drops drastically. In FS20 the green arc/banana was behaving strange because it was very far from the TOC, while the airplane was near TOC. Now in FS24 the TOC point oscillates to adapt to the green arc/banana, but the engine envelope is the same as before, probably wrong in my opinion.
  6. The same happens with the default TBM and many not so complex default liners in FS24.
  7. In MSFS 2024 catastrophic fps drop at TO and landing, today with the default TBM, unusable (but it happens with the liners too). Almost all the Inibuilds/Asobo Airbuses and the B737max have the wing flex asymmetry syndrome. The question should be what's missing from MSFS 2020.
  8. Driver change doesn't solve anything, and the bug was there episodically, unsolved for the last 2 years at least, Asobo was unable to reproduce it.
  9. Let asobo fix the issue, at the moment there is no way to solve anything for us.

  11. Not in my case, I tried those "channels" and ended with my account suspended. Anyway, yesterday I didn't find anything wrong with live weather in Italy flying the PMDG DC6.
  12. I tried to share my feedback in the official forum, but I got my account suspended. Yes, I'm in the most recent Beta and I'm trying to see how this thing is working. Already reported the wing flex animation bug, and I can add that flying the TBM is a stutter nightmare, it is unflyable and the my 12GB VRAM is full. But the PMDG DC-6 seems working good now.
  13. The wrong wing flex animation is still there for almost all default liners, it seems that nobody cares about this ugly bug.
  14. The difference is when you are on the ground, with all that displacement mapping, the complex trees, complex meshes and lights, etc. It makes the PG still more difficult to render it properly in my opinion.
