DA40NG - Beyond the 3D model, the plane needs a serious overhaul

[GUILLEWICK]

ISSUE DESCRIPTION

Description of the issue:

The DA40NG is a beautiful plane and a joy to fly in real life. It has so many characteristics that make it a great trainer and an awesome plane, so it’s a pity to experience how poorly modeled its flight characteristics are in MSFS.
While default aircraft are not expected to be at studio level, there are some basics that should be there, given the great quality of some of the included aircraft.

The list of items to be reported is quite extensive, but the most important points are summarized in this post:

• Climb, cruise, and descent speeds are incorrect.
• RPMs are also incorrect for every power setting.
• FADEC is not simulated/working properly. The RPMs will always go to the redline during takeoff, for instance; in real life, this will never happen unless there is a mechanical failure.
• Fuel flow is incorrect.

These issues are not exclusive to MSFS2024; they were also noted in MSFS2020 but were corrected, which makes it even stranger because it seems you’ve reintroduced old bugs in the new code.

I would strongly suggest contacting the COWS developer, who authored an amazing rendition of the DA42 and is currently working on the DA40. They really know what they’re talking about. Their planes fly accurately according to the numbers in the manual.

[MSFS2024] Diamond Aircraft DA40 NG

Hello folks, I fly the DA40 NG in real life, and I’m no expert, but there are several things worth mentioning. The plane flies around 125 KT with 75% load, but in the sim, it doesn’t. This plane has FADEC, and the RPMs will never go into the yellow/red arc unless something is going wrong (e.g., RPM overspeed due to a jammed prop governor). It’s a really stable plane, and when you push it out of its equilibrium state, it responds gently. Flying it in the sim feels like flying a kite. I could…

Do you have the same issue if you follow the OP’s steps to reproduce it?
• I have the same issues on the Xbox Series X.

Provide extra information to complete the original description of the issue:
• It is currently almost impossible to land the DA40NG because the plane will be way to fast and the brakes almost do not work. Currently the plane is not even beta quality please fix this.
