DA62X Improvement Mod (v0.4.2, Jun 22)

This mod aims to improve the default DA62 in as many aspects as possible.
Also included is a modified checklist that takes into account missing features and a quick rundown of the added systems (G1000, FADEC and Anti-Ice)

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. Compatibile with the Working Title G1000 mod
  • Fixed Load, RPM indications
  • Added systems and fuel page with funtional fuel totaliser (G1000 mod)
  • Correct Engine and Ammeter indication behaviour
  • Added Aux tank fuel indication
  • CAS messages added for Engine, Anti ice, Gear, 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
  • Increased flap lift and drag
  • Increased gear drag
  • Tighter turn radius on the ground
  1. Systems
  • Completely redone Anti-Ice systems with modes/endurance and functional Ice-Light
  • Functional windshield defrost
  • ECU Tests, functional ECU voters and feathering*
  • Simulated fuel/gearbox temperature
  • Adjustable standby instrument brightness (linked to G1000)
  • Improved autopilot PIDs with correct lateral and vertical limitations
  1. Visuals
  • Improved Internal cockpit lighting and ambience
  • Added white Navlight
  • Strobes behave like LED strobes
  • Added metal leading edge and MT logo to static prop
  • I Recommend these liveries from BilingualHarp7. They are specifically made to be compatible with the DA62X
  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
  • Deice fluid can be reset (must be fully shutdown on the ground with the parking brake on)
  • Added Debugging CAS messages to help figuring out mod compatibility


  • Add/fix feathering animations (im not capable of this)
  • VMC and spin behavior (when tail stalling is added)

Thanks for the help:

Thanks for trying to improve this AC.

Not a massive fan of the stock version and hardly ever fly in it. Looking forward to trying your version.

Thanks and also looking forward to have you guys make an improvement mod - sadly this first iteration crashes the sim before you even get to flight planning. Crashed 4 times in a row in the menu screens - removed it and all was normal. In case it was conflicting with modifications I had already made to engines.cfg, target performance.cfg, ai.cfg, aircraft.cfg and systems.cfg - I deleted the DA62 in official and redownloaded it and tried your mod with a completely fresh install - it still CTD’d.

oh ■■■■, really?

it worked for me, i just zipped the folder i had in my Community folder.


I will take a look tomorrow. Sorry bout that

Crashing for me too. Idk if this matter but the plane select by the last time i flyied is da62. Crash 3 times after load the sim. Deleted the mod folder worked

Yep crash in menu for me too. No need to apologise. It is a Beta after all :slight_smile:
Going to try changing a/c before loading it up then switch to it. See if this is causing the issue.

Ok so selected another AC then put the folder back in and could load main menu. Went to my hangar and the DA62 Beta was selected automatically.

so worked if you close the game with other aircraft in hangar?

I can get to main menu by selecting a different aircraft before closing and then putting the files in the community folder. Select the aircraft and start a flight. I now have an issue where the throttle will not move forward? It kind of just shakes and makes a horrible grinding noise. Using a Saitek X52 if that has any difference.
That was trying from cold and dark. Just going to try from runway RTG.
Same issue with throttle moving back and forth.

I think you have to use f2 and f3 for the different throttle gates. I had to give it up for now as I have easy access to a throttle flying, but no easy access to a keyboard. For testing, I loaded it and it crashed before I could get to the menu when it was the last plane I flew. The sim started, then crashed when selecting it when it wasn’t the last plane I flew.

Not a problem at all - just happy people are looking at the Da62 for an improvement mod - it’s by far my favourite plane. Best looking GA in the stable too :slight_smile:

Sorry for the janky start. :grimacing:

ill take look and add some documentation.

I only fly 2 aircraft exclusively atm which is the Mooney M20 and the DA62. That was why when I saw this thread I was super excited! Stayed up too late last night trying the mod out.

@ MrTommymxr

Every time very appreciated Community work,

but on other side I don’t know if it brings something what we really need. We need improvement of all default planes and with change of sim, you’ll need also do maybe big changes again so it’s very possible go to some problems with sim functionality. Good luck and maybe I’ll try your addon because very like stock DA62 as my now preferable aircraft for IFR flights.

I certainly appreciate what @MrTommymxr is doing and yes all default a/c need work but I dont know how long it will take Asobo to fix these due to them needing to fix more critical “bugs” with the whole program first, so really appreciate the speed at which these community fixes are coming out.


personally im worried that they will have their own official fixes right after we have ours. rendering all the time spent useless

You could see it as them integrating your hard work into the base code, or being inspired by it. You are pushing the sim forward.:+1:t3:

Agree. I am pretty sure that Asobo “use” community fixes in their updates. It feels like some of them have anyway. I dont think its useless the time you spend.
And “their” fixes I highly doubt will be in “Right after” aka soon™ you have done them :stuck_out_tongue_winking_eye:

Updated download. the Layout.json was broken.

Sorry for the inconvenience.

Still same issue with CTD if aircraft (DA62) already selected when last exiting MSFS.

EDIT - Ok now it CTD even without a/c previously selected

gonna remove everything and redownload it
