Controls and Indicators
Other Trafc Symbol
On alternate displays the Other Trafc (OT) symbol represents an
intruder aircraft that has been detected within the selected display
range and vertical display mode, but which has not generated a TA or
a PA. The symbol is white or cyan on color alternate displays.
On some alternate displays, OT symbols disappear when a TA occurs,
and reappear (if still in range) once the TA goes away. Some alternate
displays can also have options set to lter out all OT symbols.
Proximity Advisory Symbol
The Proximity Advisory (PA) represents an intruder aircraft that has
not generated a TA, but which is within a horizontal range of 4 nmi and
a relative altitude of ±1200 ft. The symbol is white or cyan on color
alternate displays.
Ownship Symbol
This symbol (cyan or white on color alternate displays) represents the
aircraft’s relative position and heading.
Off-Scale Trafc Advisory (TA)
This function is limited to Lynx NGT-9000 with TAS or ATAS enabled.
The Off-Scale Trafc Advisory symbol (amber on color alternate
displays) represents a TA that has been detected beyond the current
display range. The symbol is displayed at a position along the outer
range ring that indicates the relative bearing of the intruder aircraft.
On an alternate display, a text message such as “OS” or “OFFSCALE”
may be used to indicate the presence of an off-scale TA.
