Many thanks for your answer. I’ll be monitoring that ! In the meantime I wish you all the best for your C525 release. Charles

Hi, Just a quick question. Will the G500 be compatible with the future TDSim GTN when it is released ? By compatible, I mean will it be able to display approaches ? I do not own the G500 but this limitation is what refrained me from buying it (the only option was RXP but database cannot be updated). As I saw that the new C525 will be compatible (and by the way that is where I discovered that TDSsim was developing an X Plane version !) and I think that the dev team is partially the same, it made me wonder. Best regards Charles MOULIN

Thanks !

Hi, Owner of the TBM, probably very soon owner of the Challenger, looking for a discord invite if possible. Best regards. Charles MOULIN

Sorry guys, I missed that ! I am still rather new to the xplane world (compared to my 25 years with esp...). I am still fiddling with settings and I am still tuning my sim. Now that I read this, I also moved the reflection slider. I also touched VSync and Threaded optimization in my drivers but I could not reproduce the issue and figured it was not this. I totally forgot I touched this slider. Anyway, many thanks to Ghislain. And not related, but thanks to the dev team, first for this awesome plane (which I clearly think is a game changer in the Xplane world) and second for the support in this forum. Charles

Freaking strange, it seems the issue disappeared after a computer reboot. I'm trying to see if something else could explain it but I can't find anything. Running drivers 419.35 for info. Charles

+1 here same issue. If AOA is up, the issue appears. AOA down, no issue. Best regards. Charles

Thanks a lot to both of you. It may indeed have something to do with tyre friction and the fact that engine failure seems a bit sudden in XPLANE. Because the issue I have is really with the initial reaction. Once airborne the 737 is a bit tricky with an engine out especially at high gross weight, but it does seem realistic (here I have difficulties also, but because of my lack of skills !). Anyway, I really appreciate your help. Charles

Well, that's what I call fast support ! Thanks a lot for your help. Just a small confirmation: as I do not know a good take off performance calculator for that plane, I usually use FMC computed V Speeds. I guess the V1 it provides should be OK as long as I am not limited by the runway length or obstacle clearances. Could you confirm that assumption is right with regards to that specific issue ? What I might do is trigger the engine failure 2 or 3 knots above V1 just to be on the safe side regarding Vmcg. Charles

Hi IXEG team, My question is especially directed to Jan. First of all all what I will say below is with X-Plane 11.05 and IXEG 1.2 Here is my issue: I want to practice some engine failures at V1. I am using default XPlane failure (engine failure at a specific speed which I arm for V1). I tried it at different weights. My problem is that I have the feeling that the initial reaction of the aircraft is way too abrupt and rudder not efficient enough. I don't have enough rudder authority to counter it, and for example if I fail Eng1 the aircraft veers to the left EXTREMELY fast and I can't even stay on the runway almost every time. (Sorry I can't be more precise). It's as if the engine goes from full power to zero power instantaneously Now, I don't pretend to be an awesome pilot of course ! The reason I have the feeling there is something strange is that I am consistently able to counter such a failure on other sims known for their quality flight models like Aerowinx PSX and Majestic Q400. Jan, I'd be interested to get your take on it or point me to a specific technique for this aircraft. All the best. Charles MOULIN

Thanks a lot ! I don't know who you are (did not find any contact on your website) but know that your work is greatly appreciated ! Congratulations for that website. Charles

First, thanks to both of you for your help. I am actually using the profile you just mentioned ( Boeing 737-300 CFM56-3 20k.txt ). But it does not include advanced performance like cost index. No big deal, though. It's just that I recently discovered this website I mentioned and got their q400 profile which seems much more detailed than the default one (more climb/descent options for example). And I read on this very forum about the existence of a B733 profile from this website tailored to the IXEG version. But the link is incorrect (all the other links I tried on this website were correct, the IXEG one is unfortunately the only broken one I could find; to be more precise, it is not broken, but pointing to the wrong profile). Charles

Hi Guys, I am looking for a PFPX profile for the IXEG 737. Apparently, there is a very good one discussed elsewhere in this forum supposed to be here: http://airlinerperformance.net/2016/04/boeing-737-300/ The problem is that the link is pointing to a B737-600 profile. And I can't seem to find anyway to contact the author of this website. If anyone knows how to contact the owner of the site, or if one of you guys has the file in question, I'd really appreciate if you could share it somehow. I hope I am posting this request in the right forum. Thanks in advance for any help. Charles

Thanks a lot for Chiming in Tchou ! Charles

I think you might have nailed it ! I am rather new to the X-Plane world and still fiddling with things. I'm using SkymaxxPro, RealWXConnector and XPNOAA weather and I think I forgot to check the wind on that specific test where I had the issue. And as an added factor, I am more used to the 737NG/747/777 screen layout and so I might not have paid attention to it on the ND. I just ran another quick and dirty test with almost no wind this time, and did not see the issue ! But once on the runway, the aircraft did not properly track centerline. But I did notice that there was no "rollout" mode on the FMA. Sorry to bother you again (promise, I'll start working on my FCOM !) but on the 737 classic, when performing an autoland, are you supposed to disengage the AP as soon as you are or the ground ? On the 747 for example, where only ailerons and elevators are controlled by AP in normal modes, when going to LAND3, rudder becomes active too, and on the runway, aircraft does follow the centerline. But once again it is not the same aircraft so this might be a 737 classic specificity. Many thanks for your very kind support. Charles

Very good news, thanks ! Regarding the approach, I'm not sure this is the explanation. (But I'm not sure it is not either...) I remember it was an ILS at LFPG but can't remember which one. I just checked on the local map as you suggested and could not spot any visible misalignment (I'm using default scenery at LFPG). What I do remember for sure was that initial LOC capture was spot on. And when closing to the runway (from 4/3 Nm onwards I would say), I saw that my plane was slightly drifting to the left, AND the LOC signal was showing just this ! What I mean is that what I saw in the outside view through the windshield matched the LOC signal I was receiving. It's just that the airplane let itself slowly drift to the left. (This was a coupled A/P approach, very stable, slowed to approach speed before glide intercept). Anyway, I'll try and see if I can reproduce it or not. If it was a one time accident, my bad, perhaps I did something wrong. And if I am able to reproduce it consistently, I'll open a new topic in the support section if that is OK. Charles

Many thanks Jan ! This is precisely the answer I was looking for. And regarding the quality of your simulation, here is what i like the most. It is not perfect yet of course, and some features are missing altogeher. But your team is 100% honest about it, stating in a list what it DOES NOT simulate. It is one of the first times I saw this and was hugely appreciated on my part. You can't imagine how many hours I lost on competing products trying to understand a behavior, just to figure out after many research that this was not simulated... Very frustrating ! And I told myself: okay, if these guys are crazy enough to publish such a list, they must have some confidence in their product ! Regarding the bugs, after browsing the forum and reading a few posts, I really once again appreciated your constructive attitude, and the fact that you are not denying anythig and working hard to improve it. By the way, I think I have an issue where the autopilot does not follow correctly the LLZ signal on autoland (initial capture is perfect, and when closing to the runway, it slowly drifts and had me land outside the runway). But I'll have to run some more tests when I have time and will make another post if needed. And regarding the product itself, although i am not an airline pilot, I do love harcdore simulations. I have all PMDG products, and made the move to Aerowinx PSX a bit less than 2 years ago. What seems to make your product stand apart in quality is the feeling of "being there". Your virtual cockpit is beautiful, the sounds are the best i've ever heard, and those small "vibrations and shakes" are the first time i see such an effect to be convincing and not just annoying. Flight model "seems" (I insist on that as I can only judge by my feeling, and readings, and so on) really good, and general smothness is much better than with PREPAR3D (even with the same FPS). For the moment, apart from the choice of aircraft (I would like to see the same quality on more "modern" liners), I don't miss PREPAR3D. The only product which is really in a league of its own is Aerowinx PSX (honestly, I'd say without a doubt that this is the best ailiner sim avaible to the general public), but you don't have this "immersion" factor that many simmers appreciate and that you got just right as it is a standalone sim with 2D panels. After some more flying I'll try to post a small review on X-Aviation, but i really wanted to let you know that you can count one more happy customer ! Keep up the good work and see you on the forums for some more questions ! Charles

By the way, I think that this capability to reduce speed "automatically " when extending the flaps is a 737 specificity due to their Smith FMS as opposed to the big Boeing which are equipped by Honeywell and don't behave that way. (or at least I think but I might be wrong) So to sum up the question would be : Without SPD intervention option, am I legally allowed to fly an RNAV approach with LNAV/VNAV minima (and using these autopilots modes), with the limitation that you mentioned (the pilot not being able to control his speed precisely). Or am I restricted to flying them with LNAV minima and using V/S for vertical guidance. And thanks for your help Eddie ! Charles

I do think that it behaves that way, but it looks more like a "default" behavior rather than a certified use. Because that would mean that once established on the approach, the pilot can not precisely maintain a speed. I had the PMDG MD11 many years ago so I don't remember precisely but I think it was more like the Airbus managed speed (meaning the pilots controls the airspeed and at some point during the final approach will tell the aircraft to reduce to its approach speed. I know it is not the full story, I am willingly oversimplifying for the purpose of this post). The problem I mention is especially true for long final segment where you are established on the final approach, but are still under assigned speed by ATC. (I do work as an ATC at LFPG where we just validated new RNAV approaches as a backup for the ILSs and I can guarantee you that if an aircraft starts slowing to final app speed at 5000 more than 12 miles away, he is going to hear from me !)

Hi everyone, This is my first post here, so let me just start by saying that even though this product is still clearly not perfect, I am absolutely amazed at what you have achieved. This aircraft alone made me decide to make the move to XPlane and so far, I am extremely pleased with what I am seeing. So really, first of all congratulations to the dev team for an amazing job, and keep up the good work. Here is my question: I read in this forum that SPD intervention was not modelled because it was not very common on the 737 Classic. So I assume it is only possible to fly an RNAV approach using LNAV minima only, or am I missing something and it is somehow possible to fly it in LNAV/VNAV with the associated minima ? I just wanted a clarification here. All the best. Charles MOULIN
