After going through the CDU setup, there are no speed/Altitude readings in ACT RTE.Am I doing something wrong?Thanks!Mark

IRS's aligned?

You mean the LEGS information? Maybe there is a discontinuity in the flightplan that prevents it from completing the calcs, check this by putting the ND in the PLN mode and stepping through each LEG.

What Dan said above..Basically any error in the plan will not allow proper calculation of the VNAV profile. I think it flags it on the warning panel as FLT CONT (or is that for something else? - man this learning curve is steeep!)Had it yesterday evening..had a stupid flight plan with impossible ascents, descents and discontinuities..Also check that your legs have the proper waypoint from T/O (SID or not) and the correct runway on the takeoff ref page

Thanks a bunch guys! ILS needed to be aligned and POS in the CDU.That's why I love the virtual aviation community. Everyone helping each other...Have a great weekend!Mark
