DA62 needs a bit of power until TD to make it smoother. Pulling power to 0 would make it sink rapidly even with proper approach speeds and you may not have enough time to compensate it with AOE.
Check the DA62 documents attached to the mod, they’re well prepared, containing a lot of info about performance too (in the checklist).
AoE in cruise is a complex topic (speed, pressure altitude, CG and other factors are affecting it) but keeping CG in the limits should not let the AC to have too much deviation. In low speed regime or close to the top operational altitude pitching up is a normal phenomena in every plane. Close to the top of the green tape on most altitudes and even with heavy load the AC should be around 0 degree nose pitch, or a bit lower - depending on the design speed for wing dihedral angle.
This might be interesting reading for you:
Hey yes, of course it makes sense: I had already seen this document inside the package BUT I didn’t think it was referring to propellers for TWO reasons:
1 - the curve described is indeed consistent with the behavior I found BUT the values of the lower peak occur in my case at 40% of the power and not at 20 as shown in the figure.
2 - I was convinced that these were engine revolutions because they correspond to the engine revolutions detected immediately after starting when the checklist asks to verify that with the accelerator lever in idle the revolutions are around 700/710. And in fact that value, reported where I go to read it, in that situation corresponds exactly to the required engine revolutions …So now I’m a little confused about the matter.
Many thanks for your explanations.
1: hmm not sure about that, maybe the curve varies with elevation, not sure. What was the airport elevation?
2: engine and prop revs are in principle the same (not completely true because there is a gearbox in-between in this aircraft, but this has a fixed ratio). Idle rpm on ground while not moving is lower. The engine itself has not enough power on idle to generate more than this 700rpm. In flight, as you pointed out, rpm on idle is higher. This means that the prop is actually driven by the airstream (and thus it decelerates your aircraft). The FADEC keeps the rpm at the desired value (with a higher rpm, you could even “brake” more) but when yourl land and come to a stop, there is just no source of power to uphold the 2100 rpm so it will drop to the 700rpm on idle eventually.
1 : KSEZ - 4830 FT.
2 - Thanks again for your expalanatiom (very interesting)
KSEZ - 4830 ft.
For 5000ft AMSL your ambient pressure can be well below 850mbar if your QNH is under 1013hpa. As it’s stated above (see Tommy’s link) below 850mbar the low power output is increased.
Game of the year…
Ive been trying to get the MD302 to work without the mod. I can get it to work, but there is a massive problem.
You should have a link on the mod download site to check/vote these issues. It’d possibly ramp up the votes and get the attention.
Would be nice if we could have the dirt and water spray effects from the default DA62 introduced in SU5 to also appear on the DA62X.

Here is an unfinished version with the de-icing fluid weight. Can you guys check how it works (or doesn’t) with your career plugins? NXi users can see the deice fluid quantity below the aux tanks
Also the broken backup battery stuff is also included.
Anyone having issues starting the aircraft? I use WT g1000. When i goto crank the engines they barely move and the mfd and standby altimeter are flashing.
Not sure if bug or feature. If it’s a feature, this could be a spoiler, so read or skip the following wall of text at your discretion.
Using the latest version from flightsim.to, v0.4.5.1, I just experienced a gear indication failure: I extended the gear to slow down because I was cleared for a shortcut and ended up being behind on my descent (I was well below Vloe). I retracted the gear when I caught up to expedite my approach (well below Vlor). When I tried to extend the gear on final (well below Vloe), I could hear that something was wrong (I really believe it was a distinctly different sound effect than usual), the “CHECK GEAR” CAS message did not disappear, the red “UNSAFE” light stayed on, I did not get three green. I retracted the gear and extended it a few times, each time with same result as before, then I roleplayed visual confirmation from ATC by switching to the outside view, and the gear appeared fully extended in spite of the “UNSAFE” indication. I landed and the gear didn’t collapse. I didn’t have failures set up in the sim and I don’t use a failure mod.
I had the same experience when I flew it last week but I had serious winds close to Vloe so I thought that’s what caused it. But nevertheless I had safe landing after tried to retract/lower it several times with the same results.
I just checked the damage speeds for the gear and its 165 knots. should be 205 iirc
I never operated the gear outside the green arc, I don’t think I was even close to 160 kts at any point during the approach. And the gear wasn’t damaged, it just didn’t indicate three green, and the sim played the wrong sound effect, but the gear was in fact fully extended and it worked on the ground – is that the expected behaviour upon overspeed damage to the gear?
Do we file this under “another SU5 weirdness”?
