777 FMC and other issues

[guy 24]

Have flown round the world now with the pss 777.Some FMC and other issues I have seen:1) When you introduce a direct in the FMC to a point that is part of a Star arrival , or to the final approach point (e.g. CF35R) or to the destination runway itself (RW35R) the fmc seems to loose orientation. The heading becomes "000" and the magenta line starts no more from the aircraft but from a point far away. 2) When you do a direct to a point (in my case it was a normal waypoint, not a Star-arrival point) situated behind the TOD(Top of descent), the TOD disappears on the ND and is replaced on the progress page by the ED(End of descent) and Vnav passes immediatly in the descent mode (even if you are 150 miles away from the Tod). You must gess then the TOD by using the descent profile on the ND for example.Otherwise Vnav functions very well3) in the 2d panel the sign of the VS (Vertical sped) is inversed.(in the VC it's ok) "-" increases and "=" decreases.4) there is a light stuttering when using the zoom panel especially on the ground. 5) Have had the CDU-freeze also, but fortunately only twice.Hope those issues will not be forgotten in the next patch.Guy
