Gpsv Mode - Honeywell BENDIXKing xCruze 110 Operating Handbook

6.4.5. GPSV Mode

The vertical GPS Steering mode or GPSV mode is engaged
automatically with GPSS mode if the vertical steering signal is
present and the autopilot is in altitude hold mode. This mode is
displayed with the addition of GPSV to the GPSS that appears in the
upper left of the autopilot display bar. If the autopilot is engaged
during a climb or descent, the autopilot must be put into altitude
hold mode (see section 6.4.2) to get GPSV. The only exception is if
the autopilot is engaged remotely from an EFIS. Figure 6.4.5a shows
the autopilot in GPSS and GPSV.
