Thanks for the correction guys and the liveries are beautiful.
Lemme just sayâŠthis mod is beautiful. Thanks for the good work.
Having a little issue though.
Did a landing with a left crosswind of 18 kts. Upon landing, there was not enough right rudder to keep the aircraft on the runway and hence i had an excursion off to the left. Same thing happened on takeoff, and on a second landing. Rudder just seemed not to be effective past a certain point.
Couldnt find any official documentation about a max crosswind for this aircraft type but a trusty google search revealed one source saying 35kts for landing.
Am I doing something wrong, or is this an issue that needs fixing/can be fixed?
Thanks
Max crosswind component is 15 knots for the 40 i believe.
but i will say that i have not tested crosswind landings on the mods
I found this in the Manual:
Max. demonstrated crosswind component : 25 kt

25! on a castering nosewheel?
Yep, page 5-10
Ok thanks for the info guys. I guess this proves that the behavior of the aircraft was not realistic. Can anything be done regarding this?
I donât have any time in the real aircraft, but the aircraft user manual does mention that some differential breaking is required both for landing and takeoff in high cross wind situations. I have managed to keep the aircraft centered in the sim this way, but I admit it becomes very tricky when the crosswind component is greater than 20kts.

Thank youâŠgoing to give that a try.
The word âdemonstratedâ, kinda means a test pilot was able to land and take-off/land in the DA40 under these conditions. As a low hour real time pilot, you should not fly in these conditions. You have to work your way up to the max. Itâs a recommendation 
At the place I rent - you canât fly with higher than 12kt-15kt x-wind, unless you are with an instructor.

Well for me with the Mod MSFS always crashes. Without no Problems
My understanding is this is a result of the âmodernâ aerodynamic design of the Diamond aircraft, where the area of the fuselage between the passenger area and the tail tapers down to a very narrow section. This reduces the net moment due to crosswind, allowing for a higher demonstrated crosswind capability.

Yesterday, when I ran out of fuel with the runway in sight . I noticed that there was still some fuel left but it wasnât used. I turns out that a tank is empty when thereâs still 3.78L left.
I know that you canât fully empty a tank and some other parts and that amount is defined as unusable fuel. I wasnât sure if this is correct so I looked it up in the manual and it states on page 7-33:
When the fuel quantity indicator reads zero, only the unusable fuel remains in the tank.
The useable capacity of each tank is 19.5 US gal, the maximum quantity that can be
indicated is 14 US gal. Up to an actual quantity of 14 US gal the indication is correct. At
an actual quantity above 14 US gal the indication remains at 14 US gal.
and on page 6-3
unusable fuel (2.0 US gal / approx. 7.6 liter).
If you set the fuel level to 100% you get 73.79L which exactly matches 19.5 US gal. So MSFS seems to substract the unusable fuel from the usable amount which is understandable. However, in the case of the DA40NG you end up with less fuel than is documented.
So if my assumptions are correct, the amount of fuel should be increased to 20.5 or the amount of unusable fuel should be reduced to 0 to get a more realistic simulation.
thanks!

thanks, i missed that.
Happy to make a little contribution to your fine mod 
I noticed some other data in the flight_model.cfg file which is different from the reference
In the cfg file
full_flaps_stall_speed = 60 ; Knots True (KTAS)
according to the reference specs
58 kts CAS
htail_incidence = 1.5 ; Horizontal tail incidence (DEGREES)
But the basic manual says: Angle of incidence : -3.0° relative to longitudinal axis of airplane
And the max flaps extented speed seems to be to low as the documentation mentions the following values: 98 LDG and T/O 110 but in the cfg file its set to 91. In 2.3 it mentions that the white arc has a range of 60 to 98 so I think that 98 is a more realistic value.
And I also didnât expect this value to be set to 1 for the NG version in engines.cfg:
diesel = 1 ; Is it diesel engine?
I noticed that your mod has changed max_rated_hp from 168 to 1 but there must have been a good reason for this.
A quick scan shows some other figures to be slightly off as well but I guess it doesnât make much sense to change them or maybe there will be undesirable side effects. For example:
In engine.cfg the max oil temperature set to: oil_temp_heating_constant = 750 ; max oil temperature degrees Rankine which converts to 143.51 degrees Celsius but the manual states that this should be 140 degrees Celcius.
The NG is a Diesel/Jet A engine. The TDI was the older Thielert engine, the NG has the Austro Engine AE300 (after Thielert went bancrupt). The DA40XLT is the new generation gasoline variant with a 180HP Lycoming.
Well spotted.
Im in the process of redoing the DA40 right now, but shes being a 
itch right now.
The tail incidence still needs turning. In combination with the flaps, this is giving me a hard time.
143c is the max temperature it CAN get. 140 is the redzone. Dont overheat and there wont be a problem.
the âdiesel_engine=1â allows for the whole glow plug system to, exist.
Max Hp 1 was set to fix the fuel pumps. its only a debugging value.

Thanks, I overlooked the diesel part, the manual doesnât directly state this although I should have known if I had read the address of Austro (which is printed in the documentation):
Austro Engine GmbH
Rudolf Diesel-Str. 11
A-2700 Wiener Neustadt
AUSTRIA
Sorry to hear that the modding is real hard atm. I really hope that youâll be able to fix the AP âcrashâ when selecting a different approach.
