Altitudes associated with arrival and approach procedures are “auto-designated”.
This means the system will automatically use the altitudes loaded with the arrival or
approach for giving vertical flight path guidance outside the FAF. Note that these alti-
tudes will be displayed as small light blue text.
Altitudes that have been designated for use in vertical navigation may also be made
“non-designated” by placing the cursor over the desired altitude and pressing the CLR
Key. The altitude is now displayed only as a reference. It will not be used to give flight
path vertical guidance. Other displayed altitudes may change due to re-calculations
or rendered invalid as a result of manually changing an altitude to a non-designated
altitude.
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.
