A video speeaks better than a thounsand words...

OFC autoland @ EGLC is not allowed AFAIK... yet the tests under gusting winds, withing the operational limits, also look strange 😕

jcomm the uninstaller.  Sounds like another XP user has made the switch.  Is X Plane dead?

Ehehe, Oh No!  Have been playing the Toliss and the Zibo there as much as time permits :-)

and looking fwd into XP12 ... :-)

Exactly right on.

I wished these guys educate themselves and understand the aircraft's limitations and requirements before making statements like that.

I don't understand why he would one expect any good performance in a scenario like that from PMDG or Fenix when x-win autoland limitations or even normal x-wind recommended are exceeded or maximum/minimum G/S angle is out of limits.

Thank goodness, a voice of sanity!

Indeed the video linked in the OP is misleading in that the tests are done under extreme or unplausible / unrealistic scenarios, namely:

- not supposed to take place at EGLC IRL for the first two tests;

- winds above max certified during the autoland tests under gusting winds;

Then the question beckons - why post it?

I've done 5 autolands in the Fenix and 50+ in the FBW, all within operational limits - no problems... Don't own the 737

Some just like to stir up some controversy, over almost anything. 😉

Say what? Operation limits of darwinland ?  LOL Those videos are horrific display of poor airmanship, overlying on automation, and complete violation of safety practices  LOL You may as well post videos of airliners land on aircraft carriers "within operational limits" LOL

 

FYI this is what autoland is designed for:

Well, I myself have completed a few successful autolands in the FBW and the PMDG 737, but regarding the linked videos, and you just like others in this thread, missed my point... I might as well have posted lot's of other examples of users "using" MFS, or other sims, based on the principle of demonstrating the necessary outcome of using a flight simulator for a completely different purpose of what it was meant for...

I believe I pointed out the fact that it is not supposed to execute autolands at EGLC, and the x-wind videos were both recorded with wind above the max demonstrated x-wind components for both aircraft IRL not to mention the use of incorrect control inputs for instance when landing the 737 without ROLLOUT mode under such strong x-winds...

So, when people watch these videos IF they do not pay attention to such details they may well fall into the temptation of wrongly evaluating the qualities of the underlying sim or addon.

Anyway, some posts bellow in the thread you'll find exactly mention to this.

This being said, I have also used the FBW A32N and the PMDG 737, and landed both within acceptable limits, and I can tell you that I was more satisfied with the FBW performance. I do not own the Fenix A320, but I'm on the fence... BTW, and because I mentioned XP11 some posts above in an answer for Greazer, the same applies for X-Plane 11, landing even it's best airlinber addons, such as the Toliss A319.

This is such a topsy-turvy thing to have posted! All else being equal, a higher-fidelity add-on aircraft will perform less well in out-of-spec conditions, than one which is less faithful to real-life performance in such conditions. The model which is indifferent to whether conditions are out-of-spec, is in no relevant way better than one which responds to them.

Short of seeing how the real aircraft behave attempting it in such conditions, it's a stretch to say which one is more accurate / high fidelity - certainly not a conclusion that can be drawn from this video. 

Just because it's out of spec doesn't mean it won't do it.

I would like to emphasize (sorry, I just have to) that the reason for the FBW A32NX performing these autolands way better, is not an unrealistic flightmodel, but the contrary. Our flightmodel and autoland just works as it should (in real life). Hence it does its job.

You have autoland data for a 38kt crosswind in an A320?

Not sure if this is the case for others, but the AP in any sim that I can remember including MSFS won’t work very well with very poor frame rates/performance, so it’s a pretty skewed comparison. 
Also wonder what’s going on with the performance in the video, i see a 2-5 fps difference between F-a320 and P-737

¯\_(ツ)_/¯ 

So wait... you took two complex aircrafts, and landed them in a non-authorized autoland maneuver, for which the airplane is not designed, at an airport with a 5.5 degree glideslope, and you're complaining about the landing rates?

What? If anything it's an indictment of the FBW A20N that it seems to be magically able to do this... the airplane is not designed to land on a nearly SIX DEGREE glidepath using the autopilot. The E190SR has steep approach approval for LCY, but I don't even think they modified that to be able to do an autoland.

Go do an actually meaningful test at a normal airport, then come back and list your complaints please.

If you see the whole picture and history it‘s quite „funny“.

When the A32NX in the past did not perform well in various conditions people complained. Things were improved.

Now the so much beloved study lever aircraft is not performing as it should and guess what? Even that is turned into „it‘s more realistic because it needs to fail“.

I‘ve done a over the limits crosswind landing in a A320 certified flight simulator with 40 kn of crosswind. It flared good and landed on the runway but then had some struggles holding the centerline, but it did not exit the runway at any time.

I‘m tired arguing this because I think it‘s anyhow totally ignored or even it‘s turned around that people that invested a lot of time and energy into a freeware plane are laughed at now while over 1.5 years many had a lot of fun with it.

I think I‘m done with this and I don‘t see why I should keep investing my lifetime into something that is being treated by people like this and a way where technical discussion are not made open minded.
