RNAV approach - level of service VS vertical mode
 

Hi,

I was always taught not to use VNAV vertical mode when the Level of Service only shows LNAV. I’ m myself a sim instructor on Global 6000 and we teach it this way. I flew the 737 and the Embraer 175....same story.

Now I’m working in the corporate on a Lear 45 and all guys are using VNAV no matter what the LOS is. I would like to show them book references but I can’ find anything with the Lear.

would you have anything to refer me to?

thanks

I don't know what you are reffering to with Level of Service, but at my airline (737) we can use VNAV for all approaches, regardless whether it's a normal NPA, RNAV to LNAV minima or APV (LNAV/VNAV).

I don't see a reason why you wouldn't be able to use VNAV on any approach, if the procedure is coded correctly and VNAV is available...

737 here as well and we use VNAV, however, I heard on our 757 fleet they use V/S.
