direction increments through the
TCAS ranges and conversely
counterclockwise rotation of the TCAS
Range Switch decrements through the
TCAS ranges. The TCAS range does
not roll over when the range is at its
minimum or maximum (i. e. stops at
“15”). The TCAS ranges are “3”, “5”,
“10”, “15”, “20” and “40”, and are
annunciated on the display.
Above/Norm/Below tells the
TCAS to display traffic Above(8700
feet above & 2700 feet below), Below
(2700 feet above & 8700 feet below)
or Normal (2700 feet above & below).
The TCAS Above/Norm/Below
selection is sequenced through by
pressing the ON/OFF Switch. The
TCAS Above/Norm/Below selection is
annunciated on the display as “ ˆ ” for
Above and “ ˇ ” for Below. If both the
up and down arrows are displayed the
mode is Norm.

transponder system and/or altitude
encoder should be performed if the
