DA40-NGX Improvement Mod (v0.9.0.1, JUN 05)

This mod aims to improve the default DA40NG in as many aspects as possible.

Key Features.

  1. FADEC

The FADEC controls manifold pressure, injected fuel quantity and propeller speed according to the desired engine power preselected with the power lever. The RPM will follow the RPM set curve. (Further details in the included PDF)

  1. Engine changes
  • Accurate engine performance in relation to pressure altitude and temperature
  • More accurate fuel flows
  • More accurate Oil/Coolant temperature and pressure behaviour
  • Fixed Fuel Pumps (no fuel flow increase)
  1. Compatible with the Working Title G1000 mod
  • Added systems and fuel page with funtional fuel totaliser (G1000 mod)
  • Correct Engine and Ammeter indication behaviour
  • CAS messages added for Engine, Failures and other systems.
  1. Flightmodel
  • Cruise speeds and climb rates more closely match AFM numbers
  • Smoother less twitchy control compared to default
  • Improved Cl table and stall characteristics
  • Added nose wheel steering (Can be removed)
  • Increased flap lift and drag
  1. Systems
  • Increased Fuel capacity to 19.5 gal usable per side
  • ECU run-up
  • Functional windshield defrost (always on)
  • Simulated fuel/gearbox temperature
  • Improved autopilot PIDs with correct lateral and vertical limitations
  1. Visuals
  • Improved Internal cockpit lighting and ambience
  • Added white Navlight
  • Strobes behave like Quad Flash strobes
  • Prop Mod from @BilingualHarp7
  • I Recommend these liveries from BilingualHarp7. They are specifically made to be compatible with the DA40NGX
  1. Other
  • Engine will sputter and fail when pushed too hard
  • Oil and fuel starvation when flying inverted.
  • Fuel totaliser can be reset using the ELT
  • Added Debugging CAS messages to help figuring out mod compatibility


  • Make the Voter switches 3 positions(haven’t figured this out)

Great work! Your mods make the sim so much better! Thank you.


I still get the flashing 2300 RPM all the time in the non Fadec version. Is this a known issue? Otherwise it feels pretty good… although I would say being able to hold the same rate of climb up to 11000 feet I am not sure is super realistic. Cheers.

Thats how it’s supposed to be.
The FADEC controls the RPM. if you are not using it they you have to control the RPM yourself. The RPMs are in the readme.
Shift F2-F3 I think.

On a normal day the AE300 can make full power up to around 12-13K.

maybe im dumb i cant download the googledrive file

works by me :confused:

Thank you, finding myself spending MANY hours in the DA-40. :slightly_smiling_face: :clap:

Any thoughts on hosting this on Github like many others?

im a noob with github. But ill look into it

Just wonderfull. Waiting for da62 :sweat_smile:

Started the 62 thread.
Ill clean it up later


So happy someone is giving this plane the treatment it deserves. Can’t wait until the FADEC is good to go with throttle quadrants. Keep up the awesome work!

We might be able to steal some code from the A320. There is some logic inbetween the thrust levers and engines.


Please fix it so I and many more can enjoy what you and the others have given us! The plane is a joy to fly. The more realistic touches it has, the better. :smiley:
I’m really fond of the modified flightmodel as well, so shoutout to Philipe and Alexis for this! :slight_smile:

Added the high-altitude idle power correction combustion extinction thingy

Possible to put on google drive or whatever? Hate nexusmods because registration and slow download links

Thanks! Now works! =)

Hi, great work! On non-FADEC, I’m getting a really low engine load (39%) with my RPMs in the yellow. I also get the Vacuum low master caution. How do I fix please?

Also Engine, System and Fuel pages don’t appear (I have the latest WT mod)
