Can I do an RNAV / RNP / LNAV / VNAV / LPV approach in the CSS 737 Classic?
The 737 Classic is not equipped with GPS so it cannot do some of the more modern approaches.

All of these approaches require GPS, which the CSS 737 Classic is not equipped with. Additionally, the FMC software does not allow for VNAV approaches.
Your best substitute is using V/S mode and manually calculating the vertical speed to maintain the proper glidepath angle!
