SimWorks Studios announced GA8 Airvan

The landing problems I am having are in normal flat runways with minimal winds.

And I think stall is related to airspeed which would take into account headwinds or tailwinds - only the ground speed will be different.

Yeah, so I don’t think your plane is stalling, it just doesn’t glide well, and cutting power is leading to a large change in VS. I haven’t flown this in a while. When I was, the biggest issue I had was collapsing landing gear with even the gentlest of landings.

I believe it’s been updated at least once since then so I should check it out. If it were cited somewhere IRL we could use the SDK to compare its lift to drag ratio or L/D.

I’m inclined to agree on the suspension front. It doesn’t look like it compresses at all, and just skips along.

Even under heavy breaking, simulating a rejected takeoff, the nose doesn’t appear to dip then either. Maybe the real plane has no nose wheel suspension, for all I know.

That’s actually pretty tame for a grass strip. Try it in a random field somewhere (not crazy bumpy but not a strip).

But according to this it should be capable of that kind of terrain and that is what I was expecting. It just doesn’t make sense in the sim :frowning:

I think two important values for the contact points in light of this are:

https://docs.flightsimulator.com/msfs2024/html/5_Content_Configuration/CFG_Files/flight_model_cfg.htm?rhhlterm=contact%20point%20points&rhsearch=contact%20points

“set_max_compression” is set to 1, so parameter 9 is setting the max compression, in feet.

Parameter 8, and 9 are set to 0.01, and 0.18, respectively.

point.0 = Name:wheel_c#Properties:1,4.6,0,-4.19,1500,0,1.302,40,0.01,0.18 ,0.5,2,2,0,0,0,0,1 ; EV_033

0.01 is pretty close to 0, or rigid. 0.18 feet is 2.16 inches, so very little compression at all.

I went looking through my Community planes to find any others with “set_max_compression=1” so I am comparing Apples with Apples.

Only the BBS Islander, and the Airvan, have adopted this approach. All others are using the ratio method.

The Islander has 0.2, and 1 respectively, or 1 foot of travel.

Problem solved, we have an update in testing that should fix it.

We have news for the Airvan users:

We are currently testing a fix for the landing gear collapsing on rough terrain, affecting both MSFS 2020 and 2024. We will give our testers time to work through it and release when we are back from the Easter break.

On the SystemsPulse side for MSFS 2024, electrical failures are working again and we are now pushing to restore the missing engine failures before release. We are targeting completion around the time SU5 drops, as that update is expected to fix the broken persistence system in MSFS 2024.

Gear collapse seemed inconsistent to me. It didn’t always do it, but when it did I was very gentle in lowering the nose.

If it it’s a tricky one, it’s a feature I would completely disable until it works perfectly in testing.
