I would make sure that you check-mark the box beside Disable turbulence and thermal effects on aircraft found in ALT > Options > Settings > Display > Weather . This might be the cause of the problems with the autopilot.

Use SHIFT+7 to bring up the CDU. Then press the RAD NAV button. Look at the entry level with LSK 4L (Line Select Key 4 Left), and you should see something like 110.10/335PARK. The 110.10/335 is the ILS frequency and RWY heading. This should activate when you are between 20 and 10 nm from the airport, but sometimes it doesn't. All you need to do is click on LSK 4L (copy the ILS/HDG into the scratchpad), then click it a second time to "paste" the ILS/HDG back into there. It is then appears like this: 110.10/335M, which means it is ready to capture the ILS/HDG.

I hope this helps.

Anybody any idea at all?

Hi,

It is turning right and then left and starting to stall after every takeoff (when I push the CMD A).

Read some topic about this then I controlled the CG and flapsettings. And I guess settings are true. (3,6 trim - 5 Flap setting) (And Thrust Mode is To/GA)

I am really not finding out the problem...

Thanks for your help,

Last night I completed a flight from La Guardia, NY, to Cleveland, OH, (KLGA to KCLE), flying the US Air 757, and did an auto landing on RWY 24L, which was successful.  I had to go around on the first try because I had selected the wrong ILS frequency on the NAV radio, but the second attempt worked.  I set up the IRS, which took quite awhile to respond correctly.  Whether this is necessary I am not sure.  There is good documentation in the CS-757 manual, Part 2, on using the IRS to allow the normal operational mode of the NAV mode, which may be helpful.  There are also two tutorial flights for the 757.  The CS-757 is a great aircraft, and I hope you can get the autopilot issue resolved.
