Why does the plane drag to the right on takeoff

[Darren]

Every time i take off my plane drags to the right even the hud symbology is not centred when im airborne .its ofsett to the right is this normal.how can it be fixed if it is not normal i am totally lost even with a symetric load out it does it .any help would be greatly appreciated

[159th_Viper]

Wind.

[Mugenjin]

Trim to 'fix' it (not that there's something to fix to begin with :P ).

[Essah]

Correct with Rudder, Don't use Nose wheel stear as you can mess it up.

[Demongornot]

Wind, problem with your yaw axis with your game controler who rudder stay on the right or with the channel who control the right engine and who have less power than then left.

[Darren]

So its wind and not a bug im no expert guys so why does my hud symbology ofset to the right is this a way of telling the pilot of direction of a crosswind if so why is it centred on the ground cheers for the replys.

[Fish]

Assymetric load out will have an impact, but wont affect the HUD.

 

Wind always 'blows' the FPM symbology 'downwind', so to stay on course you point the nose 'upwind' For assymetric loadout, apply roll trim to keep aircraft level. (All only after rotation).

Because the flightpath marker and therefore the pitch ladder show your flightpath, and your flightpath is affected by the wind. If you are on the ground your landing gear's friction with the ground prevents the wind from causing you to drift.

Eddie your a dimond makes total sence now m8 cheers ,i still find it bloody hard to go down the centre line but that is a skill i will have to master i guess it makes it harder if the yaw is on the joystick not a pedal well thats my excuse lol.

Actually, there are times you will want to apply roll input (I guess not trim) during your takeoff roll prior to actual takeoff. A heavy cross wind will have the tendancy to life the upwind wing. As the aircraft get's lighter on it's wheels with increasing speed this can actually roll the aircraft. Then, immediately after life off you can have a snap roll from the wind lifting this wing.

 

This is actually particularly important in light GA aircraft. In strong crosswinds in such an aircraft, you'll actually start your takeoff roll with significant aileron input to put the upwind wind down (sometimes in line with what would be needed to make a 30-40 degree bank). As you pick up speed and the control surfaces become more active you ease out this aileron input to just a small bit of upwind wing down so that you takeoff in a wings level attitude.

check your inclinometer (slip indicator) and see if you are slipping. trim the rudder if you are. re-center rudder peddles.

[Depth]

Also keep in mind that the nosewheel is off-centre. It will always jitter and turn on its own.

[LcSummers]

Hi folks,

 

as we talking about wind, what is light, what are heavy winds in M/S (meter per second if i am right)?

 

Thanks

This is interresting. How do you trim the rudder please ? I was looking in control options for some "Trim Rudder Left / Right" shortcuts the other day but I didn't find any. I didn't check the manual yet TBH 'cause I haven't been playing now for a while but this interrests me now when I see you mention it.

[Waxi]

There is a yaw trim knob on the forward left console, which should allow trimming the rudder. (I don't know if it works since I have never used it so far.)

[Eddie]

Rudder trim in the A-10 is for emergencies only (engine failure or other battle damage). SAS takes care of turn coordination.

[july865]

eddie is correct

if you do notice that you are not "on the ball" in level flight, it could possibly be that your rudders are commanding unwanted input. check their centering ability.

[lanmancz]

Right. It's not the input problem by the way. I was thinking of trimming the rudder during landing in crosswinds or once during an energency - I got pretty damaged in the mission and my plane was constantly drifting right (my right engine was gone + some other damage) so I had to apply strong left rudder input to counter that and during that time I was thinking if I can trim the rudder somehow. But I didn't have time to play with buttons in cockpit during that emergency. I focused on landing on nearest airport ... and I crashed by the way :-) But thanks, I will look more into it in the manual.

Actually, this is not wind. I noticed this in my testing long ago. I created a wind free mission and found the same thing. To test it:

- Create a mission with no wind

- Take off and set Path AP with +5 pitch

- Increase speed to +10 and watch the fade

(note: more weapons/fuel load increases effect)

 

I wrote this up, but the dev replied that this is an intended effect from the airframe physics.

could it be that you had a asymmetrical load ? - having the sidewinders on board is enough to trigger this "drift" (IIRC) even when there is no wind.

Darren, my Saitek combat pedals had sticky brake inputs to DCS A-10, during takeoff roll caused a left or right drag.

 

Fixed with 50% dead zone on both brake axis.

 

If you have problems with the toe brakes of the combat pedals, take a look at this post: http://forums.eagle.ru/showpost.php?p=1398683&postcount=8

 

It solved the problem of stuck brakes for me.

Sorry for OT..

....again, again and again,... :P

 

no need to manually edit the registry! -> there is a tool for this task:

 

Second:Clear Calibration Utility

 

This tool clears/erases the stored calibration of a controller out of the registry from windows - so it calibrates again after you used the "one click" tool and reconnected your controller.

This helps especially if you have a "missing range" in your axis or it is not centered properly.

>>corrupt calibration? crazy joystick response? Use this tools Fix it:

 

 

Just make sure after you have used this tool every controller is in center/normal state when you plug it in and you will move them to all min/max and hold them there - so windows have enough time to recognize it and store a new calibration.

I have a related question - why does the A-10 itself always need to be trimmed LWD? Even if I'm flying slick I always have to roll to the left to get stable flight. It's really nothing, just curious. The -1 should have the CG graph in it and offer some explanation.

 

On another note, I'm going to try to convince our pilots to get me a copy of the 1F-15E-1 and maybe even the 1F-15E-34-1-1... it'd actually be very useful for my job, on top of simply being fun to have.

[Depth]

Even with no loadout?

[Frostiken]

From what I remember yeah. Even with all manner of loadouts I've always, always had to trim LWD once I'm in the air.
