GTS 800 Interface
Altitude Display Mode
The GTS 8XX has four altitude display modes:
Normal (±2,700 feet, Above (-2,700 feet to +9,000
feet), Below (-9,000 feet to +2,700 feet), and Unre-
stricted (±9,900 feet). The GTS 8XX continues to track
up to 30 intruder aircraft within its maximum surveil-
lance range, regardless of the altitude display mode
selected.
The selected altitude display mode is displayed in
the upper left-hand corner of the Traffic page.
The name of the selected altitude display mode (ABV: look up,
NRM: normal, BLW: look down, or UNR: unrestricted) is displayed
in the upper left-hand corner of the Traffic Screen. The GTS 8XX
series continues to track up to 30 intruder aircraft within its
maximum surveillance range, regardless of the altitude display
mode selected.
To change the Altitude Display Mode:
1. From the Traffic Page, turn the
cursor
on,
highlight the current mode and turn the
small
right
knob to cycle through the options.
2. With each turn of the knob, the screen changes
to display the traffic detected within the selected
altitude display range. The 400W/500W Series
screen also displays unrestricted traffic (UNR)
having a range of maximum specified by the
GTS 8XX series unit Pilot’s Guide. Please refer
to the GTS 8XX series unit Pilot’s Guide for
information regarding altitude display ranges.
3. Note that confirmation is not required. The
mode is changed immediately when using the
