[Auto Throttle on SP2b]

Hi Adrián,

I've spent hours and hours searching for a solution but in my opinion the problem is related with the way some wx engines set the wind conditions.

It looks like they fluctuate the winds very quickly and frequently, probably too quickly for FS to notice it but fast enough for my auto-throttle controller code to go crazy (and not only mine, I've seen that other add-ons also have issues with this).

Basically the auto-throttle code is a so called PID controller that constantly compares the actual airspeed to the set airspeed. Based on the difference between the two but also based on the rate at which the airspeed changes, it will command the throttle input. Very fast, small changes can have the same or even a bigger impact on the throttle output that slow but large changes. And I think that this is exactly what happens with these add-ons, very fast changes will signal to the controller that you are experiencing moderate to severe wind shearing and the auto-throttle will react likely by big inputs.

Hi Björn,

Yep, I see... Well, there is not problem, it's the price I have to pay for flying this aweosme bus (I don't know if this sentence is well said )

I'll continue flying the A300 even without a real WX engine hahaha.

Thank you for your support Björn!

Cheers,

Adrián

Hi Bjorn,

It flies perfect without Active Sky. Just smooth as it should fly. The question is in the air ... Will be a fix or something like that to be able to fly with these weather engines without problems?

Thanks for your great support

Cheers,

Yes, of course. I will give it a try and I'll tell you if that solves the issue

Cheers,

Adrián

Hi Adrián,

Can you disable your REX or Active Sky completely if that solves the issue?

Björn

[Auto Throttle on SP2b]

Hi Bjorn, thanks for your quick answer.

Yes, I have REX installed, but only textures. The REX weather engine is deactivated, and I use Active Sky Evolution.

Cheers,

Adrián

Hi Adrián,

We have seen this behavior when the aircraft is used in combination with REX.

Can you confirm if you have REX installed?

[Auto Throttle on SP2b]

Hi guys,

Well, I installed a few days ago the SP2b, wich I downloaded from the "Updates" section on the web. I started the simulator, and loaded the flight with the Airbus. I took-off, and everything was fine... until I switched on the auto throttle. I set 220knots on the MCP, and the plane just accelerated until 260, and then, speed fell to 180, and then to 230... and finally on 220. Then, when the airplane wants, he just goes crazy and decelerates, or accelerates "at his own discretion". That's a bit annoying because I can't maintain very well a speed, and things comes worse when trying to maintain a speed flying online, within a controlled airspace. Is this problem something common on the SP2b, or is it just on my PC?

Thanks for your great support

Cheers,

Adrián

[Annoying Problems With The A300]

Well, I have made all you said. I checked the FSUIPC.log, and all you said is done. I opened the FSUIPC.ini and the SimConnectStallTime was on 2. I wrote 3 and i saved.

I launched FSX... and it still doesn't working properly.... I don't know what more can I do... definetly my Sim Check is very crazy...

I also have to say that, the pitch sometimes goes crazy. For example, if i set on the vertical speed 3000 fpm when taking off, after 10 seconds in the air, it goes to 7000 fpm, and i have to disengaged the A/P

Adrian.

Hi Adrian,

OK I see what you mean, please check my remarks about the FSUIPC.log file and the change in the FSUIPC.ini file.

The FSUIPC.ini file is also located in the "Modules" folder.

Open it with Notepad and in the first section:

"[General]"

Add this line:

"SimConnectStallTime=3"

and see if that changes things for you.

I write to FSUIPC offsets for the autothrottle and to set the flight surfaces for the lateral navigation. When anything is wrong with FSUIPC or the communication with FSUIPC the system will stop working. As the FD bars are moving correctly it looks like the A/P code is calculating the settings correctly but these are not communicated to FSUIPC or FSUIPC (which is talking to SimConnect) has lost the connection to SimConnect and is not sending any commands to FS.

Björn

Ok, I will try it, and I will tell you in a few minutes if it works

Thank you so much!

Adrian

There is the problem

If you don't see anything due to the quality of the video, tell me

Hmm, now I really hvae no idea what may be happening. You don't have any entries in the FSUIPC log about SimConnect disconnects right?

There is no reason that I know of why the A/P would stop working altogether, same for the A/T. We only ever saw the problems when there was an FSUIPC disconnect. The big question is why it worked before and it doesn't work now! Something must have changed between the "before" and "after" moments, but what ? Can yous end me screenshot of your panel when the A/T and and A/P don't work so I can see your settings ?

This is what I have on FSUIPC4.log about SimConnect:

Hi Bjorn,

The lateral mode NEVER works. At first flights, it was working fine, but in one flight, when I was arriving, it just stopped working, and since that flight, the lateral mode has not returned to work.

I also tried what you have said in your last post yesterday before write this post today. It doesn't work. I don't know what's happening... I can turn the airplane via the number keypad, also when the A/P is engaged, but i can't do this with the joystick (with A/P engaged)... I can't understand that...

Concerning to the N1 mode... I have tried to set the thrust at 70% (and more) before engage N1 mode. It still doesn't work. And also, when airborne, setting the SPD mode, it doesn't maintain the speed. It just maintain the last N1 adjust and he continues accelerating until 400KIAS. I have to manage the speed manually with the Saitek's throttle.

Regards,

Adrian.

Hi Bjorn,

Yes I do, I have the latest FSUIPC (4.60) registered, and I didn't touch anything about axis, controls, or something like that in the FSUIPC settings.

Concerning to the HDG.... the same as the NAV.... if I set (for example) HDG 140, the autopilot won't follow that heading. It's like the airplane couldn't follow the lateral navigation.

Adrian.

[Annoying Problems With The A300]

Hi all,

I bought two weeks ago the boxed Simcheck A300, and at first, all was working properly. A day, I decided to make another flight with the 'bus, and all was fine until I had to make the arrival to the airport, which I had to make manually because the autopilot was unable to follow the INS route. The FD seems to want to follow the route, but the airplane doesn't turn. I decided to uninstall the airplane, and make a fresh install. My surprise was that the airplane was worst than first time. The autopilot can't follow the route, the autothrottle doesn't work properly (I can't make a "N1" take off, because I set the thrust at 40% and then I push the N1 button, and the thrust doesn't increase, he just stays at 40%, and when I try to set the thrust at 100% with the Saitek's throttle with N1 activated, the thrust doesn't rise). I have to say that when the autopilot is engaged, and he doesn't follow the route with the NAV activated, I can't turn the airplane with the joystick, but I can turn it with the keypad, something strange.

Any idea?

Regards,

Adrian.
