ADS - Defined
• Automatic Dependent Surveillance (ADS) is a method of
surveillance that relies on automatic downlink reports from the
aircraft's avionics
– Aircraft position is determined by onboard avionics (e.g., FMS position)
– This position is reported to ATC via ADS
– ATC can ‘see’ aircraft in a similar fashion like radar
• ADS-“C” provides accurate surveillance reports in remote and
oceanic areas
– ATC establishes “contract” with aircraft for automatic position reporting thru
automatic downlink messages
– FANS 1/A
• ADS-”B” provides surveillance reports in continental airspace
– No crew action required, automatic connection
– Ground based station receivers
• Provides ATC enhanced situational awareness
– ADS provides frequent and accurate position reports

necessary info
• (ADS-C) Ground-initiated contract(s) are
established with the aircraft
– Contract specifies information and frequency of
downlinks from aircraft
– 3 different types of contracts
• (CPDLC) Clearances/Requests may be sent
and responded via FMS CDU
– Both standard messages sets and free text are
available

ATS Facilities Notification Logon
• The purpose of the AFN logon
is to:
– Allows the aircraft to logon to
ATC and transfer control
– Provide the ATSU with
information such as the flight
identification, registration and the
aircraft address
– This information allows the ATSU
to correlate the AFN logon
information with its corresponding
current flight plan
Honeywell Proprietary
C&PS Flight Technical Services
24
 Honeywell.com
The Initial AFN Logon
• An initial AFN logon is needed when the aircraft does not already
have an ADS-C or CPDLC connection, such as when:
– The aircraft is preparing to depart; or
– The aircraft will enter an area where data link services are available from an
area where data link services are not available; or
– Instructed by ATC (e.g., following a failed data link transfer)
Honeywell Proprietary
C&PS Flight Technical Services
25
 Honeywell.com
ATS Facilities Notification Logon
• When initiating the logon, the flight
crew should verify the following:
– The aircraft identification provided when
initiating the logon exactly matches the
aircraft identification (Item 7) of the filed
flight plan;
– The aircraft registration provided when
initiating the logon exactly matches the
aircraft placard, when the flight crew
manually enters the aircraft registration
– The flight crew enters the four character
ICAO identifier of the ATSU to which the
AFN logon is to be sent

ATS Facilities Notification Logon
• Following the AFN logon, the ATSU sends a system level message to
the aircraft avionics. This message is known as the Connection Request
message
• ATSU establishes themselves as the Controlling data authority (CDA)
• Flight crew will receive a message indicating communication is
established

Data Link Connection Management
• When transferring CPDLC and ADSC services between FIRs, the flight
crew should not need to reinitiate a
logon
• Under normal circumstances, the
current and next ATSUs
automatically transfer CPDLC and
ADS-C services
• The transfer is seamless to the
flight crew
• The flight crew should promptly
respond to CPDLC uplinks to
minimize the risk of an open CPDLC
uplink message when transferring
to the next ATSU

How It Works – ADS-C
•
Once log on is established, the ATSU
establishes one or more contracts
with the aircraft:
–
–
–
Periodic contract
Event contract
Demand contract
ADS REVIEW
CONTRACT
ADDRESS
PERIODIC 576s
MSG CONTENT:
FLIGHT ID PRED ROUTE
EARTH REF

DDLCAXA
AIR REF
METEOROLOG A/C INTENT
ATC INDEX
•
Each contract may contain various
information regarding the aircraft
position, route, meteorological
conditions, etc.
•
Although the setting of these contracts
requires no crew action, they can be
viewed by the crew on the FMS CDU
Honeywell Proprietary
C&PS Flight Technical Services
32
 Honeywell.com
Periodic Contract
• A periodic contract allows an ATSU to specify:
– The interval at which the avionics sends an ADS-C report
– The optional ADS-C groups that are to be included in the periodic report
• The ground system may permit the controller to alter the periodic
reporting interval to allow for situations where the controller desires a
longer or shorter reporting interval
• An ATSU can establish only one periodic contract with an aircraft at
any one time.
• Up to 4 ATSUs can each establish their own periodic contract and
specify their own conditions for the report with the same aircraft at the
same time
Honeywell Proprietary
C&PS Flight Technical Services
33
 Honeywell.com
Event Contract
• An event contract allows an ATSU to request the avionics to transmit
an ADS-C report whenever a specific event occurs. The event
contract can contain multiple event types. These types of optional
events include:
–
–
–
–
Level/altitude range change event
Lateral deviation event
Vertical rate change event
Waypoint change event
• An event contract remains in place until either the ATSU cancels it or
all the specific events in it have been fulfilled
Honeywell Proprietary
C&PS Flight Technical Services
34
 Honeywell.com
Demand Contract
• A demand contract is simply a request sent by the ATSU
requesting position information from the aircraft
• The demand contract uses the existing periodic contract for
reporting criteria by the aircraft
Honeywell Proprietary
C&PS Flight Technical Services
35
 Honeywell.com
Contracts – MCDU Commands
• The FMS provides the crew with information on the
current requested ADS contracts.
Honeywell Proprietary
C&PS Flight Technical Services
36
 Honeywell.com
Cancelling ADS Contracts
• The ATSU either automatically or manually cancels an ADS
contract when it no longer needs ADS-C reports to avoid situations
leading to congestion
• The ground system cancels ADS contracts when:
– The aircraft has crossed the FIR exit position and has passed beyond the
normal “back coordination” parameter
– The ATSU has cancelled or finished the ATS flight plan for the aircraft
– The previous ATSU, the controlling authority or an adjacent ATSU needs no
further surveillance or monitoring information for the flight
Honeywell Proprietary
C&PS Flight Technical Services
37

Cancelling ADS Contracts
• The flight crew can terminate contracts on the aircraft by disabling
ADS from the ATC LOGON/STATUS page

CPDLC Connection Management
• The purpose of a CPDLC connection is to allow the exchange of
CPDLC messages between an aircraft and an ATSU
• FANS-1/A aircraft can have two CPDLC connections established
concurrently, each with a different ATSU
• Only one of these connections can be active at any given time
Honeywell Proprietary
C&PS Flight Technical Services
40
 Honeywell.com
How It Works - CPDLC
•
When a clearance uplink is received, the
crew will have to respond with ACCEPT,
REJECT, or STANDBY
•
If the ACCEPT response is selected, a
WILCO message is inserted that will be
downlinked to the ATSU
Honeywell Proprietary
C&PS Flight Technical Services
41
 Honeywell.com
How It Works - CPDLC
•
The crew may send a request via the
CDU for altitude, speed, offset and flight
plan changes.
Honeywell Proprietary
C&PS Flight Technical Services
42
 Honeywell.com
CPDLC Message Sets
• The CPDLC message set consists of a set of message elements
most of which correspond to a radiotelephony phraseology
• CPDLC message elements are referred to either as:
– “Uplinks” (message elements that are sent to an aircraft), or
– “Downlinks” (message elements that are sent by the aircraft)
• Each message element has a number of attributes associated to it,
including:
– A message number that uniquely identifies each type of message element.
Uplink message elements are prefixed “UM” and downlink messages prefixed
with “DM”
– A response attribute that defines whether or not a response is required for a
message element, and if so, what type of response is required

Multi-Element CPDLC Messages
• A CPDLC message consists of either a single message element, or a
combination of up to five message elements. A CPDLC message that
consists of more than one message element is a multi-element
message.
• However, only one response is required for a multi-element message

Cancelling CPDLC Connections
• The flight crew can cancel CPDLC by logging off of the system
Honeywell Proprietary
C&PS Flight Technical Services
50
 Honeywell.com
CPDLC Communications
• In addition to the benefits of the direct communications link, other
advantages associated with CPDLC include:
– Allowing messages to be stored and reviewed as needed
– Reducing flight crew-input errors by allowing the loading of specific
uplink messages into the FMS
– Reducing workload by supporting automatically transmitted reports
when a specific event occurs, such as crossing a waypoint
– Automatic updating of the ATS flight plan when a specific downlink
message is received (Aircraft Specific)
Honeywell Proprietary
C&PS Flight Technical Services
51
 Honeywell.com
When to Use Voice & When to Use CPDLC
• When operating within airspace where CPDLC is available and
local ATC procedures do not state otherwise, CPDLC should be
the primary means of communication
• While CPDLC provides for ATC communications, voice may be a
more appropriate means depending on the circumstances
• During an emergency, the flight crew would normally revert to
voice communications
– However, the flight crew may use CPDLC for emergency
communications if it is either more expedient or if they are unable to
establish voice contact
Honeywell Proprietary
C&PS Flight Technical Services
52
 Honeywell.com
Displays and Alerts
• ATC Comm Message Alerting (Gulfstream example)
– The crew is alerted to an incoming uplink message through a combination of
CAS messages and unique aural tones
Uplink Type
Aural Alert
CAS Message
Standard
Single Tone
ATC MESSAGE (Flashes in
cyan reverse video for 5
seconds, then remains steady
Urgent
Double Chime
ATC MESSAGE (Flashes in
amber reverse video until the
master caution button is
pressed, then remains steady)
• A new aural alert is generated each time a new uplink
message is received
• CAS message is extinguished when the crew has viewed the
MCDU message
