Thank you for answering... But you said "hold" and not lock... is there a difference ? What's the difference between alt lock and alt hold (07D0 and 07D8)? Regards...

hi, I worked on a program witch needed to use the autopilot of flight simulator 2004. But i got some troubles and i hope that someone can help me... First the heading order : I send an heading order throught the offsets 07C8 (Autopilot heading lock) 07CC (Autopilot heading value, as degrees*65536/360) and the plane displayed the good heading on FCU but the trueHeding (and magHeading) have some degree of difference. The track seems to be more realistic. So do the the heading autopilot is a track autopilot or do i miss something ? The altitude order : When i wnt to managed aircraft in altitude, i use offsets 07D0 (Autopilot altitude lock) 07D4 (Autopilot altitude value, as metres*65536) and the plane never goes to the altitude order but just stay at current altitude. Do i something wrong ? Thanks for helping me....

Hi, I'm Frederic and i'm french... I use FS2004 and FSUIPC 3.411 for doing an airport graphical representation. In the document for programmers, these offsets are not declared as "ok" for FS2004. So I need to knox if I can use the value concerning as correct values or if i should do any calculus to get the real value ? Thank you for answering me ... Frederic
