Mirage STILL Pulls to the Left

[SixthFall]

Huh, unless there is a monster crosswind, the mirage behaves normally for me. In the cold start instant action, there is iirc a 9m/s crosswind at 90 degrees to the runway (50-60 km/h), then I have the issue.

[Marcus7715]

I have exactly the same issue...... fine in 1.5.3 OpenBeta, but trying to take off cold start from Runway 3L in 2.0.2 pulls violently to the left, and no amount of correction to rudder avoids a sorry end in the dirt off the runway

 

M2000C was great to fly (and still is), but without a definitive answer, I'm avoiding flying it in Nevada...

Open the mission in the mission editor and have a look at the wind direction.

There is a right to left 90 degree crosswind.

 

I changed that to line up with the runway and there is no pull to the left on takeoff.

9m/s is 32km/h or 18kt.

 

60km/h is 17m/s or 32kt...:smartass:

Thanks for the tip to use the ME to fix the crosswind. The Mirage still needs to be sorted as it should not need max rudder all the way down the runway to correct this little bit of crosswind.

Thanks for your answer, did as you suggested and decided to alter the wind in ME to a headwind, and was able to take off fine.....

 

What baffles me is because the Quick-Start missions are the obvious first port of call when you buy a new mod, the mission designer decided to make the cold-start first take-off such a challenging one ;-)

 

Thanks for your help :thumbup:

Anytime.

 

The questions I have - the quick-start missions need reviewing re: wind issues.

 

And . . . . there should not be a need for aggressive rudder with the type of wind-speed even with the 90 degree crosswind. Some rudder yes, but not to the degree that you can't stop the nose from being pushed off the runway. Needs some work methinks on the flight model. (Rudder affects.)

[Dragonares76]

I experience the same problem with landing gear binded not functionnal ...

The force that pulls to the left the Mirage is less present when i cut the AftBurner and take off with only conventionnal power. 2.0.2, Nellis AFB, quick start cold start mission.

 

Related to gyroscopic force from the engine badly calibrated, and over expressing itself ? Never happened to me before.

 

Using Warthog joystick, X55 throttle, Saitek combat pro flight rudder.

 

Can someone make an abstract of what have been said and if a possible solution have been found ?

This is interesting but we shouldn't have to do that.

Indeed operational procedures for the M-2000 mandate AftBurner use for each and every take-off. No exception. Safety rule.

good to know

I always take off without afterburner - even when fully loaded with bombs

[Harke]

I did some testing and what I have seen, ruder has almost no effect from 0 to 80 knot. When there is no wind it is sufficient to stay align, but if it blows a little, until the ruder have a true effect the plane take a too high angular velocity on the left or the right to keep on the runway

 

I think the ruder need to have more effect from 30 to 80 knot

 

 

about the AB, it only build more faster the angular velocity

Wut???? :huh:

I agree, it is not a normal behaviour of the plane. To be more concrete, the effect still present without AB, and it is really hard to keep it running straight. It occurs all along the runway until I take off. I tried to land and there was no deviation of trajectory during the braking phase.

 

Still, some have spoken about a "funky" behaviour in the final approach phase. I experiencenced a wavy trajectory up and down during the final, hard to keep the plane on a constant angle of attack.

 

Do you know if this is going to be treated as a bug by razbam or by ED ? (I know the special situation of Razbam at this time, i'm not quering for fast solve, just knowing the roadmap ^^)

 

I think Harke says that the AftBurner only let you to take off faster ... Am I right ? (au pire on parle français les gars !! :lol: )

en gros tu accélères plus vite donc tu vas plus vite dans le décor et pas le temps de rattraper sauf si très anticipé, du coup oui en buster (meme si il ne faut pas) c'est plus facile à contrôler qu'en gate :p oui j'ai un anglais de merde je sais

 

oups yes, not AF but AB

Edited April 22, 2016 by Harke

[Azrayen]

OK then AB (afterburner) not AF (not meaningful in English+means airbrakes in French)

Yes! Same experience here on both issues.

 

I didn't see other posts on the final approach phase so I thought it was correct behaviour - it does have a wavy approach and hard to keep stable within the brackets. Very sensitive to any slight pitch changes.

 

My understanding of FBW is that if you place the VVI in a particular pitch, then the aircraft will try to maintain that pitch regardless of throttle changes unless it exceeds the limitations of the flight envelope? In my observation, this is not happening either on approach or level normal flight (needs continual trim input)

[Harke]

buster and gate

 

[Fab]

Well it seem like, we bought a plane with a frame thats been damaged. When they had F-104 in Denmark, one of the planes had same problem, and they never found the problem.

[Azrayen]

Nope, that's Airbus FBW.

Different aircraft, different rules.

To get this in the M-2000C, you need AP On (which is the standard way of flying the aircraft, by the way).

With AP Off, you will get a need to trim. Possibly less than what we have in the sim for now.

Azrayen,

 

Thanks for the info good to know. Especially the standard use of AP. Curious how the approach AP will work. :)

[jojo]

Use DIRAV (NWS) to stay aligned during take off run. :smilewink:

[Deezle]

Can confirm this issue is still present with crosswind. Several updates have had notes regarding this issue yet I've never seen any difference. No other plane in DCS is this susceptible to crosswind.

[ScottyBS]

I am having the same issue - cannot get airborne.

Around 50kts aircraft will pull hard left and be unstoppable.

 

Basic user created mission 0 wind.

0 wind? :huh:

 

Would you post the mission or, even better, the track?

[clanitho]

Just an idea, Could it be a braking of the left wheel compared with the right wheel?
