Haven't flown the A350 in a while and just reloaded it into 2024 and just going down the runway, trying to take off. It pitches up uncontrollably and crashes. Yes it's the latest version. Just curious if there's something I've missed since I've been away from the A350? I quit trying to fly it because the frame rates were so bad but now on my 3080 capped I'm getting 60 frames per second and it's smooth. It just seems incredibly odd that a pay-ware, and yes, expensive add-on, all of a sudden is just pitching up and crashing. Any ideas? Thanks.

Hi Chris:

I have flown the (iniBuilds) A350 a few times, including once a couple of weeks ago. Yes, I recall, the take-off was tricky. It took me a couple of attempts to get it right.

I don't recall the exact details, but you need to rotate gently and must engage the Autopilot (green light on) shortly after take-off on positive rate of climb, in about 400'-500', which is what I did.

Hope it works out for you; it may need a couple of attempts, though ...

Once you get it going, it can keep flying...seemingly forever...🙂...especially the -900ULR.

Good luck.

First thing that comes to mind is that the take-off pitch trim was incorrectly calculated or set. I don't own the Ini A350, so don't know if it's one of the aircraft that automatically sets the pitch trim, or whether the THS value needs to be set manually?

In either case, I'd try a take off with a neutral (or even 1.0DN) T/O pitch set.

The ini A350 sets TO trim automatically. I don't know if the actual one does so, but I guess it does (or at least you have to match the CG, like in the FBW A380).

Yes, the pitch trim should be set automatically in the iniBuilds A350, unless, for the OP, some (MSFS) Assistance setting is interfering with this function.

I never have excessive pitch-up issue on takeoff in the A350; however, occasionally I’ve had trouble engaging the Autopilot, on positive climb rate.

Just tested it on an LEBL - LPPT flight and I had no extreme pitch upmon takeoff either?

Have you properly set the W&B in the INIT page, either manually or by sync with simbrief so that the correct ZFWCG is set and the corresponding THS units are calculated and set based on the takeoff flaps?

Edited February 14Feb 14 by jcomm

Glad, @jcomm, you confirmed my own experience with the A350, from several flights. I’ve now flown all the three A350 variants a few times each. I have never encountered such extreme pitch-up.

Yes, it’s important to set your 3rd-party credentials properly on the EFB, and then sync the relevant SimBrief data into the FMS/MCDU, either manually or by import.

Indeed, just now making anotherrewarding LEBL - LPPT 🙂 

Added by the Magic that Active Sky in Passive mode and Real Turb CAT areas can offer too, and all simply AMAZING 🙂

As others have said, this sounds like a trim issue. Either MSFS auto trim or you setting a wrong trim value in the PERF page.
While it does rotate a bit quickly, I haven't found any instability on takeoff with the A350

Well, I shouldn't have talked too early... Right on final to LPPT 02, WASM Crash announced on all of my ini 350 ecams 😔😔😔

End of sunday sim slot for me... Some moons ago this would have meant - uninstall!!!

😜

Oh…that’s a real bummer @jcomm … on your dedicated (early?) Sunday SIM time slot…

For me too, before the sun is fully up on the Sunday, while it’s dark outside (in Chicago winter, that’s an eternity…🙂…), and before everyone, within the house (or outside) wakes up, I like to put in a few good hours of SIM.

This weekend was different though, because of my flight earlier with the newly acquired 737-900 (made a post in the Screenshots forum, if you’re interested).

Anyway, @JYW thinks (or more correctly might think) that I’m gloating a bit over my own good luck with the A350…🙂…but, no denying, that the -900ULR has now replaced my favorite 777, as the stalwart long-hauler, in my mind and heart, letting me just complete a ~9,500 miles flight (trouble-free, I might add), the longest ever in my virtual world. I’ve openly called the -ULR a good friend now…🙂…primarily because of its novelty, it avionics/MCDU etc. being different from what I know from A- and B- since decades, speaking from the SIM, of course. The A350 feels different. 

When you get back to it @jcomm remember to quit out of the Xbox App (if applicable), and restart, that usually does it for me. Do not un-install yet. One WASM crash here in the A340 and none in the A350 for me, in numerous flights with all the three -900 variants; on short, long-haul, and ultra-long-haul routes…

Have a good rest of Sunday. After all, there are things in life other than MSFS.

Cheers…!

@P_7878,

thx for sharing your experiences !

Long ago I used to do that, get up early, sometimes around 05:00 on sundays 🙂 and go to the "cockpit"...

After many moons, and even with sometimes a good oportunity to go flying for real in my LS1-D (glider) I opt for staying at home playing being an airline pilot :-)

Have had very very few WASM crashes with FS 2024. All of them in INIBUILDS aircraft, default or my purchases (A350 and A340). This one was particularly disapointing because I knew wife was waiting for me to do some gardening, and now going for the week shopping, so, if I get a chance to "vly" (virtually fly) again today it'll only be around 08:00 PM, and that means a short hop only.

Anyway, I fully agree that th A350 is a very nice addon.

Ah! there's a weird limitation when I select the -900 for a flight because while the ULR and the -1000 variants offer "no cabin" option, which is my preferred 3d model due to the fact that I simply couldn't care less if anything in the cabin past the cockpit door isn't modeled, the -900 doesn't, so I am forced to always pick either the -1000 no cabin or the -900 ULR :-/

Gardening is soothing to the mind…my better half says…🙂…To me, however, the A350 or/and the 739 is more soothing…Oh well…

I like the -900ULR because the SIA has been running, on record, the world’s longest flight (JFK->SIN) for years now. 

They use the -900ULR, with only about 150 pax; SimBrief suggested 140. I can imagine the comfort and space in the cabin, myself a consummate sardine class passenger of long-haul flights.

I just did the (ORD->SIN) fictitious flight in the SIA colors with the -900ULR (post in Screenshots Forum). I was puzzled that SimBrief sent me westward across the globe, while the SIA (JFK->SIN) flight went eastward. Apparently, the midwestern location of ORD a bit west, of about 700 miles, makes a difference.

Anyway, do fly the one that has features you like.

I’m waiting for iniBuilds’ 350-1000ULR. I hope they bring it out for me to replicate the Qantas Project Sunrise flight…to be an unprecedented milestone in commercial aviation…

So, for you, maybe some A350 is in the horizon today after the gardening…🙂…

As long as the THS has been set correct, no need to engage AP right away. I typically hand fly this one to 10k, even out of places like EDDF and EGLL. I find she is easy to follow the FD guidance on. I am using a higher end flight stick and base from Virpil though.

Yes, I think the rare occasions I do not get the immediate green indication on pressing the AP1, is because I should be actually flying up to some more height, under the Flight Director guidance.

I agree, it’s easy to do so, w/o Autopilot engagement. I’ll do that next time, I fly the A350.
