Extended Audio Callouts
The Extended Audio Callouts is a conguration option that adds
relative bearing, relative altitude (when available) and range to the
intruder information announced as well as the normal alert (or relative
altitude, range, and vertical sense for Release 2.0 or greater) It is
available to both the TAS and ATAS functions.
• The relative bearing provides a clock bearing (e.g. “12 O’clock).
• The relative altitude (if available) announces either “High” if > 50 ft
or “Low” if < -50 ft or “Same Altitude” if > -50 ft and < 50 ft of own
altitude).
• The range in nautical miles (slant range if TA is not Non Attitude
Reporting (NAR) or Flat range if TA is NAR).
Release 2.0 or greater:
• The Vertical Sense (if available) announces either:
• “Climbing” if vertical rate is >= 500 fpm
• “Descending” if vertical rate is <= -500 fpm
• “Level” if vertical rate is > -500 fpm AND < 500 fpm
Some examples of extended audio alerts are:
• Release 1 “Trafc, Trafc, 10 O’clock high, 5 miles” This
aural announcement is for an intruder at a relative bearing of 300
degrees, at a higher altitude, 5 miles away.
• Release 2.0 or greater “Trafc, 6 O’clock same altitude, less
than a mile, level” This aural announcement is for an intruder at
a relative bearing of 180 degrees, at the same altitude, less than a
mile away, ying level.
AUDIO INHIBIT
Audio may be inhibited (canceled or suppressed) in the following
ways:
• The optional Audio Mute feature is used by an external CAWS
Alerting System to mute the Trafc Advisory system due to a
higher priority audio annunciation (i.e., stall warning > Terrain Alert
> Trafc Avoidance.)
• (Release 2.0 or greater) Press the external mounted Audio
Acknowledge Button (located on the yoke or panel) to cancel the
current aural announcement.
