Can anyone taxi on the grass/off-taxiway?

[uboats]

After f15 engine startup, I tried to taxi to runway, but due to wrong operation, f15 taxi to grass ground/ off-taxiway. Then the f15 cannot move anymore.

 

Even I made full throttle and AB, f15 stayed and didn't move. In the cockpit, just big shake.

Then I switch to another one, and AI took control of the prev f15. The amazing thing happened that AI f15 taxi on grass just as smooth as on taxiway.

 

How can I taxi f15 back to taxiway if on grass by mistake?

Eject xD

Jets and grass do not mix very well (in the sim especially). But, it is possible to taxi across the grass. You need to keep the speed up just a bit (not sure the exact mph but probably around 20 mph or so). You also have to be careful not to go to fast or that will wreck you as well. So, the best bet is to stay on the hardened surfaces.

LoL.. But no. Please don't eject. The explosion after respawn can cause other nearby planes to get damaged or leave FOD on the taxi/runway. Just go to spectate and choose your original plane again.

To me it looks like there are seperate areas for concrete and terrain, so if just roll off the taxiway you'll behave as if you were on grass, but effectively you're still on the concrete basement. When you get to the border of the two, which is a bit further out, you get stuck, absolutely nothing you can do about it because the border is invisible. This is just my theory though, I'd have to see how the terrain is modeled to prove it - that said, everything I've seen related leads to what I believe. Better just keep off the grass at all cost.

Does it mean that Ai has completely different theories of taxiing? It seems that nothing can block AI's taxiing.

[esb77]

The grass seems to have some sort of "roughness" or drag coefficient, and even planes that should do well on grass such P-51s and Su-25s tend to get stuck. They'll even get stuck on some types of roads, railbeds, and other surfaces that should be hard enough for most planes to taxi on.

 

While the value of stickiness is clearly a bit off, it is some sort of crude physics model I believe. Things like cycling the throttle and yawing the nose wheel steering can break you free in much the same way you would break a car free from snow, mud or sand. Unfortunately it can also break the landing gear.

 

If you don't want the AI to get you free try rocking the plane, hope the gear doesn't snap, and once it's moving head for the nearest tarmac never letting your speed go below about 20 kts if possible. Don't go much faster either or you might snap it off. Often this will break the steering, but if you can get to a runway most of the time you can shut down and repair.

AI controlled planes use a simplified flight model, which includes simpler ground handling physics.

Some aircraft may be able to operate from grass fields, but does fields still have to be able to hold the weight of that aircraft. Seen in many times where aircraft sink in asphalt, and supposedly hard grass. Seen most in Oshkosh EAA (98 and 99) Also saw it in Osan AB when they re-work some of our taxiway and they did not pack the asphalt correctly and F-16 made tracks as they taxi.

I think you mean ASPHALT.:megalol:

How can I taxi f15 back to taxiway if on grass by mistake?

 

You cannot do this sir, you must go back to Spectators and select another aircraft... or eject (preferably the first option)

 

You must make sure you have your Nose Wheel Steering set up as really you should never be going anywhere near the grass.

 

The F-15 is very heavy and its front wheel is tiny so it doesn't play very nicely with grass, despite the AIs performance.

 

Best thing to do is make sure you have your NWS sorted like I said, your aircraft will turn much better with this engaged and you wont have to go near the grass at all ;)

Yesterday on 104th phoenix server i saw somebody who were trying to taxi to runway doing tight turn finally finished on the gras with his f-15, tail number 044. I checked that tail number and on the list it said it was Maverick xD then he went full AB and went to spectators.

 

Was it you Mav ? :D:D:D

[TAW_Blaze]

If he didn't wear the 104th tag it was just an impostor. :D

lol, I did. thanks.

Me????..... Hell no! :D

Decided to do a little testing:

I see. I have NWS setup, but that experience was due to AFK during taxiing .....

thanks for the answer. Spectator seems to be the best solution.

but if you stop on grass, can you move forward again?

[Shahdoh]

I have couple times, though quite rarely, wiggled out by full afterburner and turning left/right, but does not really seem to work recently, at least for me, so, as I said in the video, if you stop, your done, swap to another aircraft..

NO SHIT xD

[Matis]

STUCK ON GRASS still present .... generally i am avoiding taxing on grass since i got stuck with every plane every time, but this is a huge problem when it comes to completing campaigns. Specifically with Viggen in the Wrath of Thunder, where we have to land next to airport and taxi on grass.

 

Please ED, can you remove this frustrating feature? or at least make it an option to turn on / off.

@Matis 1. Don't taxi on grass. It's not prepared for F-15 nor the Eagle is prepared for this.

2. If you reeeally have to just get to speed and keep it with throttle until you're safe to stop.

1. will do, but once in a lifetime it just happens

2. this does not work for 90 percent of the time for me not even with afterburner

 

The issue is as i have mentioned in campaign with Viggen, because of that i cannot pass to the next mission 

 

I do not own F-15, but it does not matter since every plane gets stuck on grass.

Despite that real Viggen was build to be able to land not only on concrete airstrips.

 

Though i wish the taxing in slow speeds would not be an issue for any aircraft (no breaking speed records on grass).

I know jets are not supposed to be on grass but why not to allow slow taxiing (cannot move not even with full afterburner because of grass?? come on !!!  )

 

 

[draconus]

Yes, it happens, but when you're stuck (like IRL wheels dip into the mud/soil on unprepared grass), that's it, consider it mission over, Esc > Quit. Not a pilot job to get out the aircraft.

 

You should've asked on Viggen forum. Like here, from this year:

https://forums.eagle.ru/topic/271585-stuck-in-off-road/

instead of digging in the forum graveyard.

 

Somehow I doubt it's a requirement to finish a mission.

Good luck taxiing out of there (this is obviously a much lighter aircraft than an F-15):
