DRIFTING LEFT ON TAKE OFF - OB UPDATE 6

[Rlaxoxo]

Shouldn't you pitch down on initial take off roll, generally speaking?

 

There there now we don't want to take off into the ground : D

[OldE24]

every time i have pitched down on landing it's lead to the grass....

[The Legman]

When I pitch down on landing i smash the plane into the ground.

 

I flare gently, apply airbrakes and let it bleed speed and then i let it touch down at about 100kt to apply brakes. If the RWY is "short" or i landed a bit far, i apply the chute.

For me i only had this problem with Rudder Pedals.

 

Ive had the Mirage 2000 since the Dec 25 Release.

 

And ive never had this problem except for when i plugged it to the Rudder pedals i bought (CH Pedals that i returned later as they were to narrow for me)

 

With Those rudder Pedals i had the same problem as you guys seem to Experience (As soon as you start gathering speed the aircraft Pulls hard to the side Left in my case and is pretty much impossible to stop the turn)

and i only had that problem with the rudders for the mirage all other aircraft worked fine.

 

But as soon as i went back to the Joystick Twist rudder the problem vanished.

I dont have Rudder Pedals, just the HOTAS X. On my side it is first (around 50kts) to the left and then (around 90-100kts) hard to the right.

I have exactly the same problem with fuel tanks. D:

Even if it is not right, pulling the stick slightly up during the entire takeoff roll makes it much better and doesn't drift that much.

At least that's what they teach Airbus pilots and Boeing pilots on the new generations, you apply constant down pitch until ~ 80 kts.

We were talking about take offs.

I was replying to the post before mine.

 

And to sum up on this: pulling the stick on the takeoff roll helps a lot with the drift.

makes sense, that locks the tailwheel. Pilots have been doing this since WWII :pilotfly:

[Manuel_108]

Tailwheel!? The Mirage doesn't have a tailwheel. Could the devs shed some light on this, maybe? People here are certainly confused.

99.999% sure that was a joke. Although now I kind of want a tailwheel on my Mirage.

 

Anyway, earlier in the thread:

 

[...], I was watching him try to takeoff and I see exactly the issue all of you are talking about. Us on the team must be conditioned to counter for it or something but it was enlightening watching him try to takeoff.

 

So today I did a component analysis breaking down every force and moment to build up exactly what is happening. Basically we found a couple issues with the gear collision model complicating the ground reaction behavior as well as some issue with the gear physics configuration.

 

I don't have it solved completely but it's on the right track and I'm excited to get it fixed.

 

So it's known and it's being worked on, and will be fixed when it's fixed. But the forums being what they are, people will continue to 'report' this until it's actually fixed (and then for a week or so after that).

 

It seems that pulling back lightens the load on the gear and reduces the effect of these 'issues'. Also, anticipating the behaviour helps a lot. If you correct the drift and centre your pedals once you're going straight again, you'll keep turning and wind up oscillating back and forth until you lose control.

I've noticed that it's easier to control the plane during takeoff with the nose wheel steering engaged. It's not correct from the reality standpoint but at the current state of implementation it can be considered as a temporary workaround. As son as the nose wheel steering is disabled the plane starts to drift a lot which required heavy rudder input to counter. Also the rudder seems to take an affect with a significant delay which easily can lead to an oscillation like movement - drift left - counter - drift right even more - counter more - drift left out of the runway.

I can confirm this.

There is a big problem at 100 kts when rolling on the runway. This problem is for take off and landing. When you 're taking off the aircraft steer left at 100 kts and when you're landing at 100 kts the aircraft is falling to his tail and when you're are trying to let the nosewheel touching the ground smoothly an alarm of nosewheel system is warning.

[Gliptal]

The alarm is just telling your trim isn't neutral.
