Preventing NWS Automatically Being Enabled Upon Touchdown, Landing

[gary palmer]

when front wheel touches down on runway the NWS comes on automatically. I do not like this as it is tooo sensitive at touchdown where aircraft is still moving at a higher speed.

 

Is there anything I can do to ensure it does not come on automatically upon touchdown, so that I can enable it when aircraft is moving much slower manually?

 

Thx...Gary

I am unaware of any "auto" method . I do so manually immediately on touchdown and before takeoff . Not the Natops way , but it does fall within pilot's discretion .:)

[Eaglewings]

I am not sure there is a way to do this beside manually deactivating it

Increasing the deadzone for rudder axis does help considerably in reducing sensitivity.

How are you doing that? When you're on the ground you have NWS on your HUD. You can add Hi to it when going to high gain steering but you can't remove the NWS from your HUD until you lift off and it goes off automatically. It then comes back on when you touch down.

 

How are you turning it off on the ground?

You can assign that to your controller; it's a multifunction toggle, that disables the A/P while airborne, and NWS on the ground (forgot the name in DCS' settings, sorry).

When on the ground the Autopilot/Nose wheel steering Disengage(Paddle) switch mapped to 'A' on the keyboard toggles NWS On and Off.

 

In the air, this switch toggle Off the autopilot.

You're right. I just fooled with it and got this.

 

On the ground, the NWS is on.

 

Pushing the S key will give hi gain steering as long as you hold down the S key.

 

Pushing the A key will turn off the NWS. Pushing the A key more times will do nothing. To turn NWS back on you need to push the S key. Pushing the S key again and you get high gain steering again.

 

So, to turn the NWS steering off and on and also turn high gain steering too you need to program the A and S keys to buttons or just use the keyboard.

thx all for your input... I have adjusted rudder deadzone from a 4 to an 8 and is much less sensitive for NWS upon touchdown. No left right oscillation.

 

with HI NWS if you enable it; and even see the words HI NWS on HUD; it will not work at high rate of turn (which I believe is about 75 degrees of turn) unless aircraft is moving at a very low speed...needs to be below a specific minimum speed of aircraft travel before HI NWS happens.

hope that helps...Gary

Regular NWS should have a gain based on speed as well so it doesnt go crazy as you accelerate or just after touchdown, it probably disables itself past a certain speed, commercial aircraft do it so Im making an assumption the hornet has the same logic, might be wrong but would be nice

It can happen IRL;)

 

[gary palmer]

Thanks Raelis....with DCS F18 is no gain feature according to speed of travel ...is off, on normal rate or hi rate.

NWS will turn off automatically when taking off once front wheel comes off the tarmac....gary

Which commercial aircraft ? I'm not aware of e.g. any Boeing or Airbus which have this feature.

Usually steering angle is around 6deg (low gain) with the pedals and 60deg (high gain) with the steering tiller.

I don't have any problems with the NWS in the DCS Hornet nor IRL with other aircraft.

 

edit: just checked the NATOPS manual and in the F/A-18 low gain is 16° and high gain is 75°. There's apparently no automatic switch over.

You might have misunderstood, on the airbus a320 at least the pedals NWS (Low gain as you described) the reduces its gain and max angle as speed goes up until it totally disabled at certain speed

 

Like I said I would ASSUME the hornet you have something similar but it's just a guess, if it does't have this kind of feature it doesnt make any sense for it to come on even at low gain at touchdown, sounds like something very dangerous

Why should this be dangerous?

 

E.g. on the 747, 767, A300, A310 this is simply a mechanical connection which always turns the nosewheel by a fixed amount when using the pedals.

 

On the A320 it's a typical 'new' Airbus feature and it feels rather strange IRL.

 

On the A340 it feels even worse because it is acting different during landing than during takeoff!

Takeoff > no NWS above 150kts and full deflection up to 100kts but during landing you don't get any NWS above 100kts.

What do you mean it feels kind of strange IRL? No it doesn't it makes perfect sense you don't need steering imput if you have enough IAS on the rudder

[bbrz]

What do you mean it feels kind of strange IRL? No it doesn't...

Depends on the pilot, I and many other pilots simply don't like it.

I much preferred e.g. the straight 767 way since I (usually) know what I'm doing and I don't like a computer which continuously alters the behavior of the aircraft!

Feels as artificial and lifeless like the rest of the FBW system.

[raelias]

Well i would disagree, it feels very natural and doesnt change the behavior at all, on the contrary it makes it bahave the same regardless of speed, you dont even feel it doing it. Like you said tho some might disagree

 

We are getting off track tho, question is if the hornet as a fbw jet has this feature of not

[gary palmer]

F18 has no gain feature, NWS come on when front wheel touches down and turns off when front wheel comes off the ground upon take off ... is all automatic unless pilot turns off NWS upon touchdown manually...

[Goa]

I am also looking for this feature, expcially on take off

Good to know thanks

[Flamin_Squirrel]

If you're struggling with directional control the solution isn't (or shouldn't) be to turn off the NWS. It means something else is wrong, most likely controller settings. You could concentrate on fixing that IMO, otherwise you're treating a symptom rather than the cause of your difficulties.
