hello,I red some post about some strange things about vnav, I didn't find an official position about that, so I was wondering is I

Tommy,- What is your cruize alt ?- Did you start your descent late ?- did you setup a FAF with VREF + 5 speed constraint and correct alt constraint ?A few pictures would help (last page of LEGS, PFD + ND + CDU on DES page when the disconnect happens...)thanksanthonyAnthony MertonPrecision Manuals Developmenthttp://www.precisionmanuals.com

cruise level is 350 ( THE TRIP IS ABOUT 200Nm)i reset mcp before plained todi setup a vref + 5 in approach page, i didn't set up any costrain ( except the atccompany limitation of 25010000) but i let calculate the fms all altitudes. i let it free also for the FAF altitude, the descent path is ok becouse i managed to be 1 dot below during final segment, but i got this using speedbrakes...i'm going to send some pics...tkstommyknocker

sorry my fault everthing works perfectly...;-)tkstk
