Vertical Situation Display (VSD)
The VSD presents a profile view of the airplane and its environment. Information
shown within the cyan dashed lines (enroute corridor) on the ND is shown in
profile on the VSD. The pilot selects the VSD display from the map information
selections on the MAP mode drop-down menu.
The VSD depicts terrain and waypoint information that is within the enroute
corridor on the ND. The VSD range is a function of the ND range and is depicted
on the horizontal reference scale. The normal-display VSD has the same range as
the ND except when the ND range is less than 5 NM. The full-display VSD has
twice the range of the ND – from 10 NM to 2560 NM.
The altitude reference scale is linked to the VSD range and is not independently
adjustable. This ensures that a consistent 3º glidepath is depicted up to an 80NM
range. The selected altitude shown on the VSD is the same as the selected altitude
shown on the on-side PFD.
Failure Flags and Messages
Failure flags are displayed for system failures or invalid information. Indications
are removed or replaced by dashes when source system information is not
available.
The message EXCESS DATA is displayed if the amount of information sent to the
ND exceeds the display capability. When this occurs, the primary display system
removes information from the center of the display outward; information near the
outer selected range area is still displayed. The message can be removed by:
• reducing the amount of map information
• reducing range, or
• deselecting one or more of the map information selections (STA, WPT,
APT, DATA, POS)
