Hi there,after i have installed the SU1 full, i have difficulties in using the LNAv. for instance, when i enter the route say from YMML to NZAA and all the runways needed, and then pressing LNAV botton it said that NO ACTIVE ROUTEcan anyone help me out pls!!

oh i forgot to say that i am using MS9thanks

Did you activate the route (ACTIVATE> line selected on FMC route and/or LEGS page)? Entering the route is not enough. It has to be activated, and EXECed too if I recall correctly.Lee Hetherington (KBED)

Well put Lee ;)Then one goes into MAP mode on the ND, brings up the LEGS page, and steps through the actual plan to ensure that it is actually correct.Pilots and their process :D Ray

...and for the activate prompt to appear, you need at least one wpt !anthonyAnthony MertonPrecision Manuals Developmenthttp://www.precisionmanuals.com
