NOTE: Making course changes greater than 90° during a descent with vertical
guidance may cause excessive and rapid movement of the vertical deviation
indicator, and SVS Pathways.
The system updates vertical path guidance continuously using ground speed and
the calculated distance to the Bottom of Descent (BOD). Due to turn anticipation
guidance (turn-smoothing), distance to the BOD can be affected by course changes
greater than approximately 5 degrees. Ground speed can be affected by factors such as
shifts in wind direction, aircraft power management, pitch angle, and course changes.
Abrupt and/or substantial changes to either the distance to the BOD, ground speed, or
both can cause similarly abrupt/substantial changes in vertical path guidance.
Because of turn-smoothing, changes to both distance to the BOD and ground speed
tend to be more extreme when the BOD is also a waypoint that marks a large course
change. These speed and distance changes will be accounted for in the computed
required vertical path and reflected in the vertical guidance indications.
