VNAV

Recommended Posts

I've got a question on proper vnav use. I've read the tutorial and forum entries that state that vnav and lvl change are more utilized than vs. That works fine on climb out but on descent and approach with atc I find vs a more efficient flow. Also when on vnav somehow I descended right through the altitude entered in the cdu at a particular waypoint. Any best practices advice with vnav?ThanksDoug Wilson

From what I've read, pilots use VS and LVL CHG much more than VNAV on arrivals. It is great having a VNAV that works so well, but you can't ignore ATC instructions, and that is what you are dealing with most all of the time.Even if you are using VNAV, you are supposed to place your target altitude in the MCP each time.I've seen this done on the Justplanes videos and read posts by airline pilots that confirmed it too.Descending all the way to the glide slope using VNAV would be a rare occurance.
