GPSV OPTION FOR THE PRO PILOT AUTOPILOT

GPSV Steering features use the ARINC 429 data stream provided by some GPS receivers and EFIS systems. When a WAAS enabled GPS receiver (such as the Garmin 400W or 500W series) is used, the autopilot will follow the roll commands to the extent that it will fly complete lateral flight plans, including procedure turns and RNAV GPS approaches. The GPSV function allows vertical tracking of RNAV LPV, LNAV/VNAV and LNAV +V descents into approved airports.

As the aircraft approaches the waypoint prior to the Final Approach Fix, it is in the Altitude Hold mode. Once inside the initial waypoint, the GPSV LED will begin to flash, indicating that the descent signal is present. The bottom right side of the display changes to indicate that the descent line is above the aircraft. The distance to the descent line is displayed in feet.

Just prior to intercepting the descent line, the Pro Pilot will command a "bend over" to initiate the intercept without overshoot. The GPSV LED then glows steadily, indicating the descent profile is active. As the aircraft tracks the vertical descent, the display continues to show vertical tracking accuracy.
