grass or dirt runway

Hi there,
Do the grass or dirt runways affect the landing distance as they do in real life?
Thanks in advance.
Best landings to all

As far as I know the type of pavement does not affect the distance to stop a plane.

Ok then, thanks! I use more and more GA short runways and wanted to be sure I 'd get the right landing distance estimate… to avoid crashing at the end!
It would be more realistic though if the surface material had an effect on roll.

I agree with @Mats; I never noticed a difference in IF between the different runway surfaces.

Thanks. Grass should help slowing down the plane, dirt also a bit but less. We might get that one day, together with weaker brakes, thay would help!
Best to all.

Wow…

I was actually curious about this. Doesn’t Ice affect the distance of stopping a plane? Doesn’t the plane like slide across the ice? Like the runways in Antarctica

Yes, it does. Normally a dirt/grass runway stops a plane faster since there are a lot of little bumps on it and a runway which has ice on it or a runway which is made of snow/ice prevents the plane from stopping.

In IF, the physics of a paved runway are the same as every other airport. ;)

Too bad though. I guess one more line of code! Devs surely hav better improvements to imagine and implement than grass, dirt and ice!

I got a funny picture about infinite flight and realism and nice planes and stuff. PM me for ot. It got removed last time.

It’s not really needed right now

Maybe add a feature request if you want this

Here’s a related topic request pertaining to weather affecting runway performance. Perhaps give this a peek :)

Not that i have experienced, no

Many thanks for the link. Reason why I was asking about that is that I made a spreadsheet to calculate appr. speed, TD GS, ground roll and landing distance given altitude, temperature, wind direction, speed and aircraft weight for the TBM.
It seems to give values that match well the Sim, but alas, the brakes are way to strong right now. I am sure this will be improved one day. One thing at a time!

Thanks but I think devs are aware of this and they surely have more essential things to work out. I was just asking as I did not have any idea if grass already helped with braking.

Not nessarly. It really depends. Grass can be pretty hard to get traction on. And dirt will wither stop you dead if it’s soft, or be medium when dry. Also generally they are harder to maintain traction because bumps and rocks are constantly bumping you around, and any time your wheels aren’t on the ground, they aren’t stopping you. Also if it’s muddy you’re going to sink down in, and you’re going to stop like a rock. Speaking of rocks those are also a big threat. Sucked into the engine the consequences are obvious, but they are also slippery, and bumpy. Grass is also super slippery when wet. Long story it’s complicated. That I would say is that main reason it is not in IF, too many factors affect it in to many ways. But no, it is not simulated…

Many thanks for your message. I actually read the TBM PIM again and I was wrong indeed! It says hard grass increases LD by 7%, high grass by 25%, short grass by 10%…
I got that the wrong way around when I first read that section…
Given all the uncertainties tied to dirt or grass landing, I’ll try my best to avoid them from now on! Don’t want to damage my nice TBM.
I understand from your message that you are a real pilot. It is kind of you to give bits of actual knowledge to the members of the community.

I’m actually not a pilot. I’m just a mountain biker so I know a thing or two about dirt, lol. 😂 🚵🏻‍♂️

Also thanks for the numbers, I’m just saying generalizations another dirt above, so pretty awesome to know that numbers! Thanks!

Wow! I can’t ride on roads…
Best of luck and keep safe!
