Mirage STILL Pulls to the Left

[IceGryphon]

Just checking but do you line up and roll forward to bring the nose wheel straight before disengaging the NWS? I've found that that helps and haven't had issues for the past few updates. Also putting a slight amount of back pressure on the stick once you hit 110 kts or so helps to unweight that nose gear.

 

The last time I couldn't stay straight I remembered that I had forgotten to straighten up and it seems that when you disengage the NWS it wants to hold a bit of whatever direction is was pointing when you turned it off.

 

I tried this on cold-start still seems to be pulling left after awhile in flight.

It will go straight until I start making turns and then it just pulls left into circles. I do have that stupid Decol light on so maybe I am missing something.

[hypomaniac]

DECOL means that your take-off configuration was incorrect. Probably because you didn't test you FBW system. That's usually the case in my experience.

Have just flown instant action cold start and take-off missions in 2.0.3 and have noticed that the severe drift to the left is still there. Mirage feels and seems to fly differently than in 1.5.4. Anyone else observed this ?

No I don't feel anything differently tho I'm flying in my own Mission

 

try to Rearm the aircraft and then try to take off

[haffende]

Tried re-arming and and makes no difference it still wants to go left around 50 Knots down the runway. This was pretty much corrected on 1.5.4.

[Xenovia]

i just yaw it a little to the right and im good

[Goldsmack]

I have the same issue some times and other times its fine

 

I noticed that correcting with rudder input on the RWY after landing or before take-off seems to be overly accumulative in terms of the aircraft's responses: one has to constantly correct, but each correction leads to an increasingly amplified response from the aircraft. When adding brakes to the mix, the aircraft is almost impossible to control on the ground.

 

I know its irreverent and probably not the same issue but your description reminds me of an episode of Jetstream...Great Canadian show btw...where a student pilot was landing a CF-18 and the aircraft started pulling left but she countered with to much right rudder then over correct again to the left. She was literally 1.5 sec away from rolling the aircraft luckily the instructor in the back seat took over. I'm trying to remember the technical term for it but it escapes me.

Check your axis' in controls, I had a problem where it was binding my left toe break to the roll function which caused me to roll to the left constantly.

[firmek]

It's not a binding problem.

Just noticed it recently also though after coming back to Mirage after a break. The problem seems to be more apparent on the MP servers than in SP.

After applying a small correction on the rudder during the takeoff it almost feels like the rudder inputs are lagging and exaggerating. What I mean by that is that after applying an initial rudder and centering it back it feels like the rudder is not disengaged at that moment and continues to be applied and even increase to be disengaged quite after the pilot did it. Maybe but this is just an unsupported guessing the problem is related to the FBW system.

 

I have a decent rudder pedals, have no issues with taking off in any other aircraft as also flying choppers a lot which makes me believe that it's rather not a problem of a pilots doing something wrong.

[haffende]

Has Capt.Smiley got anything to say on this.....he spent a lot of time and effort resolving this in 1.5......does the relevant 1.5 code transfer directly over to 2.0.3 ?....at this point I would think it does not because they are very different beasts(for me) heading down the runway at the moment. As mentioned previously this problem could once be cured by simply changing to a clean configuration or changing wind direction and then it went straight as a die. would be nice to get this fixed to 1.5.4 standard.

[firmek]

Hi, I'll do my best to replicate the problem and post a track later today. Just to clarify I was refering to latest 1.5.4 (obviously before todays update).

[Davee]

Hey guys, the code is completely identical so not sure what's going on and I have been unable to recreate, could you guys get a recording or track to help me recreate what you are seeing.

 

+1 for me as well. I'll see if I can get a track tomorrow.

[IceGryphon]

Check your axis' in controls, I had a problem where it was binding my left toe break to the roll function which caused me to roll to the left constantly.

 

Even with a keyboard it will start to do this.:joystick:

Once in the Air you turn to the left and suddenly it keeps pulling left.

It slowly increases over time the amount of pull, fast or slow. Never right.

The only way to fix it is to jerk it right for a long time with the rudder and stick. Then the hud appears off center. but it will slow the effect of the pull to the left.

 

Update: Just took off and it seems to be fine this version. v1.5.4.55584.141

Pulled left and right it will recenter just fine and follow the heading.

Update

Hi !

 

I thought the problem was resolved for me until tonight but it come back on 2.0.3....

 

This afternoon I did a flight in heavy payload conf with wind and no problem to take off.

 

Tonight I did an other flight, this time in clean payload conf and still a bit of wind; but my plane was out of control during take off and I crashed. After a second crazy take off without afterburner I flew to a "secret" runway in the north east of Nellis. I landed with some difficulties but ok I was find (my friend not...). I try to took off from this runway (with afterburner) and again my plane was out of control and I crashed.

Looks like there is not enough tires ground friction in lateral motion and the plane slide on the runway same on ice....

 

This random problem is very frustrating ! :mad: Especially when you have to do a new full 8min INS alignement or in some case can't succeed to take off at all and ruins your planned flight with your friends....

 

I attach the tonight mission and track files:

[diditopgun]

I tested again my mission in solo and in MP (alone and with my friend) and this time no problem for take off...

This random bug is very strange... :huh:

Sorry but track file is too heavy (even compressed in zip....) to be attached...

 

When you clic on my link download don't start automatically ? :huh: (web site is my internet provider, no specific risk to download from it)

I upload it on my ftp, should be more easy:

I can resolve this problem in the default 2.0.3 take off mission in the mission editor by changing the 10m crosswind to a direct head wind...but in reality I suspect the real plane would not be so sensitive to a mild cross wind. In the early 1.5 releases changing the load out to clean also had an effect.

10m/s crosswind is roughly 20kt.

 

Max crosswind is 25kt.

 

Just saying...

[diditopgun]

I did a 13mps crosswind right now without issue too. The issue don't seems to be directly linked to the wind and come randomly.

[diditopgun]

Really ? OMG..... I will check immediately ! Shame on me....

[diditopgun]

Ok........ It's the parking brake and I forgot it two times.... :crazy: I am really sorry and big shame on me ! :chair:

 

I just tested and I reproduced it. Every time you take off with parking brake you finish in the grass (or sand).

 

At least it's good to finally put a finger on it and it will be more easy to check new people who will maybe still come with this "issue report" in the futur.

 

And for sure I will check this f***ing parking brake at each take off now !!! :smartass:

[Dahlbeck]

Parking brake set at runway start. Is that normal? Unless setting the parking brake is SOP at lineup before takeoff, maybe it should default to off?

[TheSnark]

The plane has enough static trust to start rolling if no brake mechanism is applied. It is only fair to put on the parking brake at the runway if someone is jumping in a hot aircraft.
