Hello,Just a quick note, in reference to another thread, but in the other way.Flying from KMIA to KPHL, I was steady in cruise, using AS2004 as external weather prog. All was quiete and perfect upto the time where I set up the FMC for the arrival and approach.After that, for any given reason, suddenly the AP goes from VNAV LNAV to MACH and start to descent, with the CWS in amber in the right side of the PFD. Using the yoke to regain control with out disconecting the AP does work fine, and after reingaging the VNAV, it goes back to the selectedc alt.This did happen 4 times in 15 minutes, upto the time it did happened when I was away from the desk.I have no idea where it comes from, but if any one of you has an idea, I would buy it.Thanks for your input and comments.Cpt Cyrille de Lattrewww.corporateaviationservices.comAsus P4P800/P4 2.4 giga/1.5 giga DDR/Ati 9700 pro 128 meg
