CAO
PANS-OPS,
Doc
8168
states
that:
-
ANS-"Pilots
shall
not
manoeuvre
their
aircraft
in
response
to
traffic
advisories
(TAs)
only"
This
point
is
emphasized
in
the
ICAO
ACAS
II
Training
Guidelines
for
pilots:
"No
manoeuvres
are
made
based
solely
on
the
information
shown
on
the
ACAS
display"
ICAO
standards
only
include
phraseology
to
report
RAs.
Therefore,
pilots
should
not
report
"TCAS
contact"
or
"we
have
it
on
TCAS"
after
traffic
information
from
ATC.
Indeed,
such
a
report
provides
no
added
value
to
ATC.
