ZAON PCAS XRX - Example 1: a Single Aircraft

UNDERSTANDING PCAS 27
Example 1: A Single Aircraft
In this example, there is only one
aircraft in the detection window.
If the aircraft is 1.9 NM away and
300 feet above and descending,
this is what the XRX screen will
show. This is an alert situation. An
attempt should be made to
visually identify this aircraft as
soon as possible.
Use the information XRX is giving
you to alter your course if the
situation warrants.
The ascent/descent indicator is
based on the target aircraft’s
actual climb or descend trend,
not the relative difference in
altitude between you and the
target. Because of this, you may
see the down arrow, meaning
the aircraft is descending, even if
you are also descending.
