MAINTENANCE MANUAL
CAS-100 COLLISION AVOIDANCE SYSTEM
The ABOVE/BELOW pushbutton is used to set relative altitude
display limits for nonthreat category aircraft on the traffic display.
(NOTE 4.)
The RANGE pushbutton is used to set the nautical mile range
scale for the TCA display. Each operation of the RANGE
pushbutton toggles through a pre-specified set of mile ranges.
When the RANGE pushbutton is operated, the CTA-100A will
toggle to the subsequent highest range value.
(NOTE 4.)
The function of the FCN pushbutton is to set the function modes
that use the CTA-100A display. When the FCN pushbutton is
pushed, the CTA-100A sets and shows the subsequent available
function mode.
The RIGHT pushbutton shows current Flight identification when
Flight ID mode is set on the display. The pushbutton is also used
to set to the subsequent character position for Flight ID data entry
before the timeout period.
The LEFT pushbutton shows the current Flight identification when
The Flight ID mode is set in the display. The selection will
backspace over previous character in ATC data entry mode and
backspace over previous character in The Flight ID mode. The
LEFT pushbutton starts the data entry mode for Flight ID when the
current Flight ID value is on the display -- backspaces over all but
the first two characters.
