I’ve managed to reproduce the dead stick landing scenario: in that case the brakes seem to work fine. In other words, it might not be the brakes themselves, as @anon40588191 suggests, but the throttle at idle provides too much thrust, slowing down the brake efficiency.
I really had high-hopes for an SU5 solution. It really doesn’t seem like a very difficult fix.
Alas, it didn’t happen.
Airbus and Boeing seemed to get most of the “love” on this one. Our numbers are probably too few.
Yep…the ~95% of sim users are loud yelling Boebus fan boys, so this is what we get…
I just tried the DA40NG for curiosity and after I landed I couldn’t stop rolling. It was as if the brakes were barely being applied. So I switched to the TDI same thing. Then I switched to the Cirrus SR22, which had perfectly functional brakes when I shut down the simulator last night, and all of a sudden now its brakes don’t work properly anymore. The heck?
pls 
Half a year later and this issue is still present. How can an airliner have better braking performance than what’s essentially a glider with an engine.
Still not there in SU6 beta 
It has been logged, I’m sure they’ll get to it 
For this whole time there’s no way to finish landing challenge normally in Dune without overrunning the runway. (Unless you turn off engine, glide close to stall speed and set parking brake on to get full braking as soon as you touch the ground)
Like how people said in this thread, the braking force just isn’t enough, and more importantly, the engines fadec are also incorrectly represented, the rpm is too correlated to the airspeed, idle thrust on ground takes years for rpm to drop; idle in the air at 75 kt, the rpm shows more than 1600 rpm. Ridiculous. Therefore besides lacking braking power, the propeller/ engine is producing way too much thrust which in terms negatively add to the problem.
I’m hopeful. Often, plane updates don’t come until the final release. That’s been historically how most have been done.
They also announced there will be follow-up AAU updates, so that’s another possible landing spot.
There are a lot of “low hanging fruit” default plane fixes I’m waiting for.
So get on it already, it’s been an Issa on my ps5 since day one and still is now! Not to mention the rpm issue when you start from inside the running aircraft. That issue applies to the other model as well. If you insist on your customers reporting on quality control issues you should at least address the issue in a timely manner!!!
Sadly, I don’t believe that jummivanna is with this forum any longer.
If, quite understandably, you’ve grown impatient with this unresolved bug there is an add-on (if even possible with a Playstation?) that corrects the braking issue and other things on the default DA40 at Flightsim.to.

Been flying for a longtime and can fly and land most of the planes. Just wanted to try the Diamond DA-40NG. One of the best planes to fly but such a shame you can’t land it with flaps set. Brakes don’t work. I guess it has something to do with higher RPM’s . Just tried landing but this time I used no flaps and came in at 70 mph and it landed fine. Doesn’t like flaps.
I did a few minutes ago. Much improved! Wouldn’t say it’s perfect, compared to other similar aircraft, but it’s stoppable, now.
I wouldn’t say the brakes are really “fixed”. I mentioned this is another post, but DA40NG braking performance is severely affected by whether the flaps are still deployed at touchdown. This was the case before SU6, and still is the case after SU6. In my post-SU6 testing, with flaps retracted and touchdown speed of 60-65, I can completely stop the plane in as little as 14 seconds. With flaps extended, it can take 21-27 seconds – easily enough to run off a short runway even if the touchdown point is perfect.
Interesting. I guess I haven’t been paying much attention, but I’ve never really tried this. I’ve kind of avoided the default DA40 and have been flying my COWS version.
I’ll definitely try out the flaps-up approach later today and update with my results.
Same here – I bought the COWS variant too, but obviously you can’t fly that in Career mode, which is 75% of my flying in MSFS2024.
Here are the results of some landings I did a few hours ago. There are a couple outliers, but having flaps down definitely resulted in longer time to come to a complete stop.
Attempt 1:
Touchdown speed 60
Power cut 1s before touchdown
Flaps 40
Stop time: 21:31
Attempt 2:
Touchdown speed 71
Power 1s before touchdown
Flaps 40
Stop time: 22:43
Attempt 3:
Touchdown speed 70
Power cut 1s before touchdown
Flaps 0
Stop time: 14:06
Attempt 4:
Touchdown speed 66
Power cut 5s before touchdown
Flaps 0
Stop time: 17:50
Attempt 5:
Touchdown speed 70
Power cut 5s before touchdown
Flaps 0
Stop time: 17:70
Attempt 6:
Touchdown speed 60
Power cut 5s before touchdown
Flaps 0
Stop time: 16:19
Attempt 7:
Touchdown speed 65
Power cut 5s before touchdown
Flaps 40
Stop time: 27:08
Have you tried the TDI variant? I tested the brakes this morning and it seemed to work better. I didn’t time it just a rough feel. I noticed at altitude before landing the da40 will just float and not lose airspeed. But the TDI this morning seemed much improved with flaps down it bled off airspeed as expected. The braking performance in career mode makes it impossible because a lot of times you are landing at unfamiliar short field airports.
I did try the TDI variant yesterday, just to compare, and it stopped as I expected. But, it was my first time flying the TDI, so I have no point of reference pre-SU6 to compare it to, nor do I even know if the same braking problem existed for the TDI pre-SU6. (With that said, the more modern NG is more appealing to me. Now that I know how to safely land it, I just bought one for Career Mode and enjoyed doing some short sightseeing missions – first time in months – for some easy “S” ratings. What an amazing view out of this cockpit.)
The difference between the TDI and NG is the engine and avionics they share the same frame and general flight dynamics so they should be similarly weighted and have similar V speeds. The best view I have found for flight seeing is the JMB Aviation VL-3 it’s a bubble top two seater the diamond 20 is similar. But the JMB has great take off and landing characteristics as an ultralight two seater. Great for short field take offs and landings and does well enough on grass strips. Just remember to put the gear down on landing.
