[KNOWN ISSUE WIP] Idle speed should be enough for taxi

[viper2097]

Regarding NATOPS (NAVAIR 01-F14AAP-1 - 7-22 7.4.5) throttle idle should be fine to sustain taxi speeds.

At the moment, you need definitely more then idle to sustain speed.

Unfortunately the DCS suspension system is incredibly tricky to get this right. We're aware of a bunch of suspension type issues and we're waiting for some more documentation before tweaking

[bell_rj]

Does this relate to the 'sticky' carrier handling?

[viper2097]

Thx Cobra for that fast reply and clarification.

So, as the F-16 is very good known for taxing already way too fast with idle, I hope that ED will do there something when they will release it "in two weeks" xD.

 

@bell_jr, no is this related in general.

Personaly, I believe that ED made the sticky carrier handling around the cat for a better and easier handling in the game... Same with the F-18.

The Mig-29 actually has a pretty good suspension model. So does your Viggen to be honest.

yeah, indeed, the mig-29 behaves incredible realistic on hte ground, particulary good is the suspension where you can see the plane bouncing a LOT as it would in real life when braking for instance. The F-14 right now as well as other modules (probably all) feel way too "stiff" regarding suspension. Hope the Tomcat can feel more like hte mig-29 some day, even more when it is a bigger plane.

The F14 taxiis like an old buckboard. Very stiff and rough. The taxi behavior at idle is being tweaked.

 

Have you noticed the power of stabilizer braking?

I actually saw you I think mention this in another thread and just started doing it during my field landings, and yes wow what a difference it makes.

[Galf]

Biggest thing I've noticed missing is that in all videos of the F-14 taxiing on land, it bounces up and down quite regularly, it's a regular up-down movement even on straight pavement.

Oh yeah noticed it as well. Also wobbled back and forth with brake application. Again, kinda like the 29 and 27 do right now in DCS.

Oh yes! Full aft stick after the nose is down and steer it with the stabilators/elevons.

Are you saying that you have real life flying hours in both models to be able to compare that to the sim or am I seeing things here?

Great to have this confirmed. ED doesn't really like to talk about shenaningans of their product, but I think it's important, done in good manners. The Hornet also has the problem that it doesn't behave like the real thing. Hornet drivers have been telling it'd be enough to advance the throttle slightly which first would just close the nozzles, but not change RPM or FF. This would be enough to start moving. In DCS, that nozzle closure isn't even modelled in that airframe, as opposed to the F-14B that has it, with an increase of RPM and FF though, but well, it's another example and very much probably is jsut different IRL as well.

Horizontal or Vertical?

 

Using Rudder inputs at least with NWS brakes a lot (Haven't tried with NWS off). I see this in other modules in DCS as well, but not as much as in the Tomcat.

 

I always pull back on the ground after touchdown, trying to keep the nose up a while for more induced drag (haven't found the sweet spot yet though), but even when it doesn't stay up, the 14 comes to halt a lot earlier than the 18. Never had problems with the runway being too short in the 'cat, except for once when I tried something I wasn't supposed to do, i.e. landing with the wings swept aft for coolness. I mean, this is a simulator after all and I like to do such things if I've got the option, simply out of curiosity.

Just look at videos and, honestly, DCS is known to have pretty damn bad ground modeling.

Ever had your wheel stick to the grass and suddenly not even full afterburner gets you out of it? :lol:

Full afterburner and full aft stick usually works. Don't ask why or how I know this. DCS bruh...

The issue is not fixing some of the issues reported, but rather doing so without breaking other things. E.g.; (not an exact example, I can't recall now) - but if we make the tires less sticky, the rollout becomes too long, or the aircraft slides around the carrier, etc.

 

We'll tweak this asap :)

[Victory205]

Exactly. This should be lower priority.

[Baz000]

The F-14 NATOPS does mention shutting off the right engine if at low gross weights to prevent the plane from building up too much speed on taxi.

 

So far I have not needed to and I suppose it is because of this issue, so the inclination would be that the jet with 2 engines running and low gross weight = enough thrust at idle to move the plane so that the only work around was to shut the right engine off on taxi.

What I'm wondering is why do you (and other modules also) have to use this "dirty trick" of sticky wheels in order to have a normal landing distance?

Shouldn't aerodynamic drag take care of this?

I felt the same thing and made a bug report as i didn't find a thread for this behavior:

Exactly. This should be lower priority.

 

For me landing is the most important part in a flight. For me it is much more important than some very indepht technically quirks in the systems- or weaponsmodelling.

How can the rollout becoming too long? When i touch down on a normal landing i don't have to touch the wheelbrakes and i still come to a full stop on a normal airport like Sochi. I think this is too short rollout or am i wrong. The problem with Idle not giving enough thrust plays a big role here

I really would like to know more about this too. How can it be that the FC3 Planes all have a good suspensionmodel and the newer released F/A-18, F-16 and F-14 are bit off in this regard. Is it possible to give some information what the problem is, as the SU-33 has such a good suspension model and also works on the carrier.

Must be the spoilers.

We will try to improve it as much as we can, as we promised. Afterall we want this part to be as realistic and immersive as everything else, too. Thank you for your kind patience in the meantime.
