Autoland performance....

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 :-/

terrible videoquality. I saw a stuttering mess.

But yeah, the Fenix A320 autoland plowed the field on the upwind side. Little unexpected it was soundly "beaten" by FBW A320 autoland. The author mentions it is due to poor ProSim autoflight, not sure if that is the whole reason?

That's a way of framing what he said in a completely different light. He said no such thing about "poor ProSim autoflight".

He says: "Does this mean that FBW created a better Autoland System than Prosim? Or does it just mean that the FBW's flightdynamics are less realistic than the Fenix?"

To come to the conclusion that he mentioned that Prosim's Autoflight System is poor, is quite a stretch.

You are correct. Poor choice of words from me.

But the Fenix did not impress in this scenario, nonetheless.

Not enough information to make a full comparison here.

The PMDG 737 ND was displaying windspeed of mostly between 34 and 45 kts, the Fenix A320 was mostly between 41 and 52 knots. Is that an issue with the Fenix's windspeed gauge on the ND reading higher, or was the crosswind not equal across both tests?
The PC was a stutterfest for the A320 compared to the 737. Does PC lag create an issue with the A320 being unable to maintain the ILS?

"The FBW 320 landed perfectly", yet no video of it doing so.

Per this video, the 737 looked good until it departed the runway tarmac. The A320 never looked comfortable.

Too many questions, not enough answers to judge fairly.

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.

FBW's A320 and Fenix A320 autolands worked perfectly for me, even with a whole lot of crosswinds.

I assume the bad performance of that individual setup is what throws the flightdynamics off. Many FBW aircraft of the past stop functioning as designed below 18FPS. Maybe that is still the case here.

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.

I love the FBW A320 experimental, never failed an autoland, for this reason I was asking myself if it is realistic, but your message is clear.

Regarding the PMDG 737 I can get good and full autolands with Fail Operational and not with Fail Passive, also che crosswind landings have their limits, it shouldn't be above 25/30kts. Is it correct?

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;

This being said:

.) I did run a few tests with the PMDG 737, within certified wind limits, and it performed acceptably.

.) I do not have the Fenix A320.

.) All of the "stress" tests I ran with the FBW A32N had excellent performance, even near the higher x-wind limits and with variable / gusting winds.

Exactly, you cannot fly an autoland with wind conditions like that in a real aircraft and then claim that one aircraft is better in handling these unrealistic conditions than an other. The whole thing is a waste of time.

I sincerely do not care about the autoland capability, it takes away all the fun.

Everyone find his own fun, but regarding the autoland in the real world it seems that a pilot has to be certified to do it.

[Maxis 1,864]

When you find yourself unable to look past 50 feet infront of you to barely meet minimums ask yourself again if you don't care about autoland. (That is .. if you cared about meeting landing requirements in the first place).

I presume one uses the sim how they please but considering i actively search for inclement wx to fly in these features and the reliability of them are important. Over time I will be able to test the 737 and the Fenix but i can attest that the FBW is rock solid in my experience using it for these type of conditions.
