Section 15. Automated Radar Terminal
Systems (ARTS)- Terminal
ARTS/STARS may be used for identifying aircraft
assigned a discrete beacon code, maintaining identity
of targets, and performing handoffs of these targets
USAF/USN. Where PIDP/DAIR equipment is capable of
performing the functions described in this section, it may
be used accordingly.
This equipment does not relieve the controller of the
responsibility to ensure proper identification, maintenance of identity, handoff of the correct target
associated with the alphanumeric data, and separation of aircraft.
5-15-3. FUNCTIONAL USE
In addition to other uses specified herein, terminal
automation may be used for the following functions:
d. Altitude information.
FAAO JO 7110.65, Para 5-2-23, Altitude Filters.
f. Ground speed.
5-15-4. SYSTEM REQUIREMENTS
Use terminal automation systems as follows:
Locally developed procedures, operating instructions, and
training material are required because of differences in
equipment capability. Such locally developed procedures
must be supplemental to those contained in this section and
must be designed to make maximum use of the ARTS
a. Inform all appropriate positions before terminating or reinstating use of the terminal automation
system at a control position. When terminating the
use of terminal automation systems, all pertinent
flight data of that position must be transferred or
b. Inform other interfaced facilities of scheduled
and unscheduled shutdowns.
c. Initiate a track/tag on all aircraft to the
maximum extent possible. As a minimum, aircraft
identification should be entered, and automated
handoff functions should be used.
d. Assigned altitude, if displayed, must be kept
current at all times. Climb and descent arrows, where
available, must be used to indicate other than level
When operating in FUSION mode, the assigned
or pilot reported altitude must be displayed and kept
current when the aircraft is in level flight.
f. The automatic altitude readout of an aircraft
under another controller's jurisdiction may be used
for vertical separation purposes without verbal
1. Operation is conducted using singlesite
radar coverage or when operating in FUSION mode.
2. Prearranged coordination procedures are
contained in a facility directive in accordance with
para 5-4-10, Prearranged Coordination,
and FAAO 7210.3, para 3-7-7, Prearranged Coordination.
3. Do not use Mode C to effect vertical
separation within a Mosaic radar configuration.
5-15-5. INFORMATION DISPLAYED
a. Two-letter ICAO designators or three-letter
designators, as appropriate, must be used unless
program limitations dictate the use of a single letter
b. Use of the inhibit/select functions to remove
displayed information no longer required must be in
accordance with local directives, which should
ensure maximum required use of the equipment.
c. Information displayed must be in accordance
with national orders and specified in local directives.
a. When a CA or MCI alert is displayed, evaluate
the reason for the alert without delay and take
FAAO JO 7110.65, Para 2-1-6, Safety Alert.
b. If another controller is involved in the alert,
initiate coordination to ensure an effective course of
action. Coordination is not required when immediate
action is dictated.
c. Suppressing/Inhibiting CA/MCI alert.
1. The suppress function may be used to
suppress the display of a specific CA/MCI alert.
2. The inhibit function must only be used to
inhibit the display of CA for aircraft routinely
engaged in operations where standard separation
criteria do not apply.
Examples of operations where standard separation criteria
do not apply are ADC practice intercept operations and air
3. Computer entry of a message suppressing a
CA/MCI alert constitutes acknowledgment for the
alert and signifies that appropriate action has or will
4. CA/MCI alert may not be suppressed or
inhibited at or for another control position without
5-15-7. INHIBITING MINIMUM SAFE
ALTITUDE WARNING (MSAW)
a. Inhibit MSAW processing of VFR aircraft and
aircraft that cancel instrument flight rules (IFR) flight
plans unless the pilot specifically requests otherwise.
FAAO JO 7110.65, Para 10-2-7, VFR Aircraft in Weather
FAAO JO 7110.65, Para 10-2-8, Radar Assistance to VFR
Aircraft in Weather Difficulty.
b. A low altitude alert may be suppressed from the
control position. Computer entry of the suppress
message constitutes an acknowledgment for the alert
and indicates that appropriate action has or will be
5-15-8. TRACK SUSPEND FUNCTION
Use the track suspend function only when data block
overlap in holding patterns or in proximity of the final
approach create an unworkable situation. If necessary
to suspend tracks, those which are not displaying
automatic altitude readouts must be suspended. If the
condition still exists, those displaying automatic
altitude readouts may then be suspended.
