Xavier, Thank you for your prompt assistance. I have viewed all 4Vids and will review again as it's obvious my retention level needs improvement. I hope you don't mind if I contact you again with a question or two as i've already read a few of your responses in the forum and it's clear to me you know your 75.  Sincerely, Chuck D.

Xavier, On startup I switch the 3 IRS Knobs to Align and they light up, I then start turning on other switches from the OH view, the Align lights go out in approx. 30 sec. I then switch the 3 knobs to NAV and the 3 Align lights  start blinking the word Align. They never stop blinking throughout the flight. Is this normal? Thanks

Here I've a problem: when dessending in FLCH mode with throttles in idle  if I decrese speed in the mcp the airplane attitude changes taking up the nose and decreasing the -V/S value and that's correct. The problem is that the Auto pilot should maintain a descend attitude even if decreased in order to permit the speed to fit the input given to the mcp; the 757 of captain sim decrease the descend attitude while slowing down but then it starts to climb!
I guess this is an incorrect behave of the CS bird... I belive that the real 757 keep on descending in FLCH mode even if the pilot decide to decrease the speed in the mcp!

Hi all,

This is my very first post on a flight simulator forum although I am not new to FSX. I have been flying for nearly two years with at least 2 hours or flight per day using other famous aircrafts such as 767, 747 and MD11 to name a few. I usually read as much as I can the procedures manual before flying an aircraft for the first time or I use video tutorials when available. So I really try to find a solution to any issue. But this time I have no answer so I decided to post a query on this forum hoping that somebody would help me. My problem is simple : I have recently bought the CS 757 pro pack and 757-300 package but the AP does not work at all. I have followed all the before take off procedures (IRS alignment, engine start, FMS programming, etc) but after take off, the aircraft just keeps on flying on manual although I pressed the CMD, LNAV and VNAV buttons. Just as if no buttons were activated... This is very frustrating... What am I doing wrong. Many thanks for your help. Luis  

Hi RichardH,

Thank you for your answer. I always engage AP after gear is retracted generally well above 100ft.

I have followed step by step this tutorial but i still get the same problem. Actually everything is fine until I press the TO/GA button to accelerate on the runway for take-off. I gently push the thrust lever to 1.10, then i press the EPR button but the plane does not accelerate (just moves slowly forward). I have to manually push the thrust levers to max thrust in order to reach v1, vr and v2 speeds. Once airborne, I retract the gear and press LNAV, VNAV, CMD as mentionned in the tutorial but nothing happens. The plane stays on his initial path and I can notice that the AP is not on because I can easily steer the wheel or reduce/increase power with the trust levers... Any other idea ? 

audiohavoc, I have reinstalled CS several times but the problem remains. Yes, I have armed both FD and A/T switched.
Everything looks fine visually (all buttons highlighted) but nothing works...

Hi Bobby,

I have tried your suggestion but with no success. Still the same problem with EPR not working during takeoff and no AP once airborne. Don't know what to do... 40 euros lost... That's sad. The aircraft seemed to be pretty cool...

Hi Bobby,

Guess what, I finally have my AP fully functional.
Well to tell the truth, I have installed CS 757 on a spare computer freshly formatted with Windows 7. Now everything is fine. What a pleasure to watch my aircraft smootly turning and crusing along its path

Probably my problems were not related directly to CS 757 but to my FSX config (lots of sceneries and other aircrafts add-ons installed). As I did not manage to isolate the problem I cannot give any piece of advice to those who are experiencing the same AP issues. Formating the whole drive and reinstalling from scratch was obviously the last option in my possession...

Anyway, I wish to thank all of you who tried to help me on this. Much appreciated. Have a safe flight with the AP on or not !
