Hello @ll,

I'm in the opinion, that the autopilot turns to early by using the LNAV mode and following the entered FMC route. So it need nearly 1-1,5 min until the aircraft is on the magenta line again. Is it normal or can I change this anywhere, because other aircraft like another company 737NG and another company 767 following the magenta line strictly without any offset.

Kind regards

Johannes

Hi everyone,

I got the 757 3 weeks ago (directly here at CS) and i am trying to figure things out. But now i need help.

My problem is the AP as well as the A/T function. I read the manuals as well as tutorials on the net. I aligned and set the IRS switches, i can program the FMS `til the PRE-FLT COMPLET message - now it starts:

1. As mentioned in the manual nr. 3, page 22 (of course i completed the previos pages) - i set the thrust levers to 1.10 EPR (with AP and A/T activated as stated in the manual) and press EPR (in the manual picture the THR button) - nothing happens. Automated start with Vr set in the IAS/MACH indicator is not working for me. In fact - my thrusters NEVER work automated. I can activate all the switches (EPR(THR) or SPD) - the lights come on but thats it. I also followed the 757-200 FMC tutorial here at the forum - it is just not working as described there.

But it gets worse:

2. After manual takeoff i activate LNAV, VNAV and press CMD (L). The plane banks voilently and starts swinging right and left with bank-angles easily exceeding 40deg. That happens no matter what i set the bank limit selector to or which command button i choose. The only way to stop the rocking is disconnect the AP.

Additionally - a flight without FMC is impossible. The planes swings too when i activate the AP - even when HDG is on HOLD. Also the V/S is not working - the light is on and i can set the value - however the plane is not following and i end up swinging with a V/S of 6kf/min. The vertical speed selector itself is without function. Only in the display itself the V/S value can be changed.

Other things: The weather radar is just stuck with the test picture. A manual can not be found using the link in the manual.

The speed bugs can only been seen in the VC.

I own the 757-200 Captain Pro Pack v.2.1 incl. the -300 and Freighter addon. All are installed right now and the described probelm happens with the -200, -300 and -200F. I also checked this behaviour with and without FSUIPC.

I own several payware addons incl. the CS 727, C 130 and 707. All are flying as intended - for me indicating that my basic FS9 setup is ok. I know that there have been a couple of problems with this plane and i waited buying it - but now after reading several reviews after v. 2.1 and almost all were very positive (the ones not so positive could at least fly the plane and did report these bugs) i got it.

The swinging is mostly found on the FSX forum of the 757. I could not find a reference to the mentioned problems here using the search function. So hopefully somebody can help me with some suggestions?? Are you using FSUIPC and if yes which version?

Thanks!

I have not noticed such problems with my system and i have both the fs9 and fsx versions in Vista, however there are some things that move 2 units per click like the DH so maybe you can try clicking when you get near the desired limit rather than holding the button?

Iam new to the captain sim 757 fs9 , can some one tell me how to get the auto pilot to work, ive read all the manuals and still cant get it to work, id be very grateful for anyones help, thankyou,Marcus.

Thankyou very much for your help, the videos are wonderful,all the best.

Hello Guys,

I've got a problem with the 757, V2.1, FS2004 in Vista. When I takeoff the aircraft is fully ready and no problems, after takeoff I switch on the AP to LNAV and FLCH. But when the ATC vectors me I have a problem. For example: I want to fly heading 250 from heading 290. So I dial this heading and push the Heading Sel button but then he doesn't fly to heading 250 but to 246 or 247. But when I press shift-z in Flight Simulator, Flight sim says I am flying heading 250 but the CS 757 says I'm flying heading 246. Maybe something wrong with the IRS alingment?

Here is a Screenshot:



As you can see here, Flight sim says i'm flying heading 300, the 757 says i'm flying heading 303, and the heading must be 300.
