December 6, 200322 yr Hey guys I am having a strange problem on the ILS of some airports including EGSS. When capturing the LOC and GS everything is fine but the AP does not align me correctly with the runway and i end up about 30 meters to the left or right of the runway..this has happened at a few airports....EGKK and SS more recently..am i doing something wrong?..the PFD shows i am misaligned too with the the LOC pink diamond thing to the left or right..the AP does nothing to correct this.Sorry if this has already been asked..i could not find what i wanted on the search.Thanks
December 7, 200322 yr Gidday,Possibly 1 of 2 things:1. Are you sure you are in VOR/LOC and GS and have both autopilots engaged? The logic for a Cat3 approach (autoland) is both NAV recievers tuned to same (and correct) station and both APs engaged.2. If 1 above is not the prob then it sounds like you are not coming out of LNAV...this is a known realworld problem and some companies insist that all LOC intercepts are done from HDG mode only.. otherwise you risk the LNAV 'paralleling' the final approach track and it never actually captures the LOC.As with all things to do with the AFDS the answer will ALWAYS be there right in front of you in the FMAs.Hope this helps,Brad
December 7, 200322 yr I think it maybe the latter, i can't remember if i still had LNAV engaged or not..will try it next time..thanks for the help! :)
