Bumpy runways and bouncing discussion

[AndreiTomescu]

See? See? With a 109 with gunpods it takes luck and skill to bring one of those babies down..

With a hill or a runway, it's much simpler!

Gentlemen, to be successful, we have to change our weapons. 🙂 

 

[Aapje]

Instead of regular cannon rounds, we should have rounds with pieces of runway asphalt.

The bumpy runaways are a nice addition. However, the underlaying mesh is way to coarse, thous the the jump-ski-effect. That needs to be toned to a level where it is more realistic. The shockabsorbers are still too stiff overall imho. In the P51 when I do a perfect three-pointer @ 120 knots I still bounce 1-2 meters back in the air. Thats is not the case in DCS where such a landing is butter-smooth.

120 for touchdown? 120 for a Mustang is definitely too much if you are after a mission, without loadout with some fuel, so it's no wonder you're bouncing. Land around 100 or even slightly less (90), with flaps, of course. If you even compare it to DCS, then it's too fast there too. No any problem now with F-51D in IL-2 Korea.

If you do it with the wrong technique, this is exactly what will happen to you:

As a group, most of us land at too high a speed, myself included.  I guess it has become a self defense mechanism from being chased back to base by a flock of angry AI, or the experience in past Sims of the aircraft not matching the low speed performance as written in the real world pilot's notes. Or it's just simple impatience.  Whatever the reason, we need to train ourselves out of this.

I saw an interesting take from a youtube regular. I think it was the guy who is a ,acrobatic real-lifepilot. His take was that IL-2 modeling of the wheel shock was either non-existant (doubt it) or is way way too stiff.

I wonder what IL2 programers would have to say to this?IL-2 programmers?

Go back to page 1 here and look for Gavrick's reply. 🙂

Well, I do since years between 120/100 Knots and it worked most of the time well, in BOX, DCS or even msfs. But then again, Im not a pilot and certainly no laminar flow wing expert. With 90 kn I usually stall. I will try hard to get better, I promise 😉. Still I think suspension is a bit to stiff.

[YoYo]

I'll try to record a video, although I'm flying in VR and it's not that easy. 

btw. from Chuck's guide.

 

[Dash,Polder]

I like doing much steeper approaches, it's easier to fly the lower speeds when you have some altitude to trade, one can accelerate much easier if necessary very quickly, can't do that in a flat approach.   Throw a curve in the approach and the control is even easier to manage.  You just have to learn them, and that's where VR with its depth and distance perceptions really shines.

My standard approach is the mid field break, maximum speed right across the runway cutting the hedges, cut power and turn and climb either prop lever back or speed brake out, when rpm drops at the top of the curve at 250mph, drop gear and throw prop forward 100% and she will help air brake for you.  Than flaps down, canopy open, trim elevator back and glide her down no power required.  It also allows you to clear yourself onto the airfield with full visual pass over it. 

It's an actual USAF style combat environment approach, 270 degrees of rising idle power turn burns off speed nicely to throw things out.  And your combat ready with speed right up to tight final.

I went back and checked, but the only thing I got out of it was he didn't really know how it should work. I did see prehaps it was fixed with version 2b? 

Well above my pay grade. I'll shut up now. 🙂

It is quite challenging to find sources describing the behavior of shock absorber struts.

A few thoughts and questions:

- why some & the YouTube-er pilot consider DCS as the reference point in all this ???? It's just another sim.

- if Mr Gavrick (and he's an engineer specific on the matter) says as stated above that data is scarce, I tend to believe him, and assume the other sim's devs had similar scarcity in finding data, so they used their aprox and...imagination.

- if something is more pleasant in a specific sim, it doesn't necessarily mean it's the truth. 

I would find it disappointing for the devs to change the specific aircraft behaviour to unproven specifics just to please the players.

Again, just my thoughts, don't throw rocks/eggs/tomatoes please.....

Well I want the sim to be as realistic as possible, within the limitations of 'flying' on a computer. What we are doing is not real, but if real pilots say it feels a bit 'off' I will tend to believe them, and hope that the devs can tune things a bit if necessary.

[SYN_Ricky]

I remember that in the early days of Il-2 BOS, some planes were also very bouncy on landing, even when putting them down gently, and it was later corrected.

The issue is that we are dealing with period planes with period fuels, period armaments and period - well - everything.
I'm a private pilot IRL, but it would be ludicrous of me to base my analysis of the aircraft in-sim, on my flying of Cessnas and Pipers. 

I am always very skeptical of channels which throw authority around on simulators via real life contemporary experience - A Christen Eagle is nothing like a P-51, even a modern P-51 is not necessarily an ideal comparison. The most convincing sources are primary sources.

I don't disagree, hopefully some primary sources will surface.

[BlitzPig_EL]

I do hope some real info is found before we get the aircraft carrier and Navy aircraft.  putting down on a carrier deck will be a real interesting time with the way things are now.

Our pilots will have life jackets so they should be ok ish.

[AndreiTomescu]

Well, i dunno what to say, Uther.... if the life jackets will have same efficiency as the G-suites, we'll have drowning issues! 🙂 

But they could throw a net on the aircraft, to settle it down. Besides the arresting hook.

The landing gear system is too "hard" in game, without very less toughness

[Dash,Polder]

The runways we are given are rough as a cob, that's a given, but is that wrong?  This started as a war of rapid movements and the build up of many airfields were needed rather fast.  I think it adds to the challenge of the game, the flavor of the period, suspension of disbelief, and I like it.  Perhaps some of the more established concrete runway main airfields could be tuned and maybe smoothed out just a bit. 

But please leave us some primitive ones in abundance, the challenge is most satisfying.  Consider them combat repaired a few times after the artillery duels passed through back and forth a time or two, or the bombers worked them over previously and your now rolling over hastily filled in craters.

[Kemnilov]

It is possible to make landing on Yak-9P without bounce, if you do it as in real life. You have to set three-point landing position at altitude 4-5 m, and make three-point landing at speed like 155-160 km/h. So suspension in this plane works as it should. I think that people who have bounce on landing do it because of too high speed, altitude and so on.

[YoYo]

I finally recorded a video showing that everything is fine. This isn't a paved airport (asphalt or concrete slabs), but a more difficult, unpaved one. No issue for F-51D. 

 

[Avimimus]

I do wonder if it was patched in the last patch? It does seem possible for me to land without bouncing now (at least when I don't obviously significantly screw up).

At least in the F-51D (which has gotten all the attention) - In the Yak-9P I remain a menace.

In my opinion, things improved in (hot fix) 002b where there was no changelog.
