[NO BUG]After carrier landing No turn despite nose wheel is (fully) turned

[jetsimace]

Hi all,

 

I can see that the nose wheel is turned to the side (confirmed in external / F2 view) - also turns even further with NWS HI engaged - but sometimes the plane only moves straight ahead with no turn.

Anti skid switch is on (yes, I forgot to turn it off...), both brakes are off.

You are probably taxiing too fast. You should be taxiing VERY SLOWLY. Try to only use one engine and be easy on the throttle.

Take an external look and you’ll see that at full left or right, the front wheel is pointed 90 degrees from where you’re trying to taxi. The solution is to not steer more than say 45 degrees

Strikeeagle345 has hit the nail in the head.

 

 

You should always try to go forward first before turning left or right, even if you only go forward 2-3cm first, it always helps.

Hi guys, thanks for your replies!

I am starting out of a standstill and when moving, then quite slow. Nose wheel e.g. is turned to the right side for about 75° (NWS HI), so the plane if moving should go to the right but not elsewhere. Instead, it was even moving slightly to the left.

Hi

 

Please add a short track replay showing the issue and we will take a look.

 

You can save a track replay when you exit a mission during the debrief screen.

 

Thanks

The best results in getting is first starting to roll and then turn nosewheel. It never works if I turn wheel max left or right and try to roll.

Also no matter what I do, if I am close to a catapult shuttle it always skids into different directions...I work around this by aligning dead on and then crawling towards the shuttle and dropping launch bar when in position.

@BIGNEWY: Here you go - e.g. please go to the end of the (attached) track when the plane goes to the left while the nose wheel is fully turned to the right.

 

This issue only seems to happen when starting to roll with too much power applied (some guys in this thread already mentioned that), but it seems to me that pushing over the nose wheel should not happen at those (low) speeds.

Anti skid has still been on.

 

(And yes, I know - it wasn't my best landing as I'm still working on my landing skills )

 

Many thanks!

Thanks for the track,

 

I would say you are using to much power, to initiate the roll when the wheel is at the high angle.

Try with minimal power it should be fine, and then turn the nose wheel.

@BIGNEWY Welcome and thanks for your quick reply!

 

 

Sure I know we don't have a race car, but I still think rolling direction is a bit too sensitive to power. Someone already proposed to use only one engine, others to first go straight and then enter the turn - seems to be very delicate to handle.

 

And why should the plane go to the left when the wheel is turned to the right?

NWS HI is very delicate, it isnt designed for high speed taxiing, only for sharp LOW speed turns like on the boat.

 

The reason it turns left when you are turning right too far is that the nose wheel will begin to skid. As it loses traction the aircraft is affected more by the drag of the rubber on the deck than by the wheel direction. When the NWS is to the right the actual wheel assembly will be shifted slightly to the left, increasing the drag on the left side and producing a turning effect to the left.

[Tholozor]

Yea, as others have said already, start the roll before turning. You have to remember that there's literally tons of weight pressing down on those tiny little wheels, therefore the friction between them and the deck is fairly significant. If the wheel doesn't start rolling before turning, it's going to just skid.

[Razi]

Also, I've understood that it is SOP (standard operating procedure) to be at idle any time you're turning on the boat to avoid blasting the whole deck during the turn. Therefore you need a little linear momentum before you begin the turn.

 

If you're into the real SOP you could taxi this way and doing so will also alleviate the wheel skidding problem at the same time.

 

Here is a good video of taxiing after a trap on the boat. You get a good view of the pilot putting the throttle to idle just before he begins to turn because his GoPro falls forward. He fixes it shortly after, but you get the idea from the first turn. (It is also this pilot that informed me of this SOP)

The behavior in game is somewhat unrealistic in that the nose wheel starts to skid at X speed no matter what.

 

Generally, unless you are on ice, nose wheel skid doesn't happen if the nose wheel is deflected while rolling (at reasonable taxi speeds)

 

The technique of rolling straight a bit before deflecting the nose wheel should alleviate most skidding but right now if you exceed the speed the skid happens no matter what.
