'After', and press the ENT key. This setting
designates whether the offset distance defines
a point before you reach the target reference

With the profile set, the vertical speed required (VSR)
is displayed. Expect the following to occur when using the
vertical navigation feature:
At one minute prior to reaching the initial descent
point, the message 'APPR VPROF - Approaching VNAV
Profile' is displayed as a PFD alert. The descent (or climb)
angle also locks to prevent changes in speed from altering
the profile. If selected, the vertical speed required (VSR)
readout on the default NAV and map pages shows the
desired vertical speed to maintain the proper descent (or
climb) angle. At 500 feet above (or below, for a climb) the
target altitude, an 'APPR TRG ALT' - Approaching Target
Altitude" message is provided. The VSR readout on the
Navigation Map Page is blanked out at this point.
