Check FINAL APP

GO AROUND ALTITUDE SETTING A/THR..………………………CHECK SPEED MODE POSITION/FLIGHT PATH……………………MONITOR

Monitor VDEV , FPV on PFD and XTK error (on the ND).

Use altitude indication versus distance to the runway to monitor the vertical navigation.

XTK

If the vertical guidance is unsatisfactory, revert to FPA FPA NAV or consider the go-around. If the lateral guidance is unsatisfactory, perform a go-around.
