3Definition of Program
- Mission
- Improve ATO efficiency Enhancing productivity of
controllers - Increase NAS capacity BY Enabling advanced
operations to reduce resource needs - Enhance air traffic safety Reducing
communications errors related to voice - Data Communications provides
- Two-way data between controllers, automation and
flight crews - Safety-of-flight air traffic control clearances,
instructions, traffic flow management, flight
crew requests and reports - Automation enhancements for ATC message
generation and exchange - Communications link carrying data between
aircraft and air traffic managers - NextGen requires Data Communications
- Necessary to transition Agency from voice based
ATC comm system to data centric NextGen

- FAA System Scope
- Program funds enhancements required to perform
data communications in - Ground User Interface (e.g. ERAM/DSR display
software) - Ground Data Processing (e.g. application software
to create clearances) - Ground Data Delivery (e.g. wide area networking
between ground facilities) - Ground components of A/G Message Delivery (e.g.
radio, ground antenna) - User System Scope
- Users fund enhancements required to perform data
communications in - Airborne components of A/G Message Delivery (e.g.
aircraft radio, antenna) - Airborne Message Delivery (e.g. aircraft
networking) - Airborne Data Processing (e.g. app s/w in comm
flight management units) - Airborne User Interface (e.g. cockpit displays
s/w)
8Program Assumptions - General
- Data comm is required to transition Agency to
NextGen Concept of Operations - Transition to NextGen required by 2025
- Large scope requires partition into phases
- Functions/services originated from Communications
Operating Concept and Requirements for the Future
Radio System, (COCR) due to international
coordination and buy-in - Not all COCR services implemented
- VDL Mode 2 is the subnetwork
9Segment 1 Functionality (2012 2017)
- Segment 1 Services will include
- Data link logon (DLL) service to provide a unique
digital identification of every aircraft - Air Traffic Control clearances (ACL),
instructions, and notifications provided in a
textual format (data messaging) between
controllers and pilots - Departure Clearances (DCL) including revisions
transmitted to the aircraft on the ground - Initial use of 4-D Trajectory clearances for
continuous descent approaches - Digital Automatic Terminal Information Service
(D-ATIS) up-links of airport weather, hazards,
and restrictions to the aircraft - Automatic ATC hand-off (ACM) data transmitted
to aircraft identifying the radio frequency in
use by the next air traffic control sector
10Segment 2 Functionality (2017 )
- Segment 2 Services will include
- Segment 1 services in TRACONS
- Segment 1 services in En Route, plus
- 4-D Trajectory Agreements in Performance Based
Airspace, providing conflict-free flight with
stable aircraft routing - Conformance Management to ensure aircraft comply
with 4-D agreements - Tailored Arrivals/Continuous Descent Approaches
and Time-based metering - Arrival Taxi Instructions (ACL, D-TAXI) prior to
landing, giving the aircraft detailed guidance
from touchdown to gate. - NAS Airport status, delays constraints,
hazardous wx uplinked to the aircrew - Taxi-in / Taxi-out service provides taxi routes
for aircraft to follow from the gate to the
runway

13WG-M Envisioned Activities in support of Data Comm
- 1. Data Comm Application level list of
anticipated standards modifications/additions - Application standards (i.e., CM, CPDLC, ADS-C)
may require changes in support of those services
specified within RTCA SC-214 Safety and
Performance Requirements, and Interoperability
requirements for Data Comm services. - PM-CPDLC message changes (as developed within
RTCA SC-214, like D-TAXI, etc.) Target Seg 1,
and Seg 2. - PM-FIS and PM-ADS-C (like the changes in DOC 9880
for PM-CPDLC) Target Seg 2 (note, the changes
for PM-FIS may be required for Seg 1) - It may also be necessary to introduce security
requirements within the Air / Ground
infrastructure in support of the Data Comm
program. Such modifications / additions to the
international standards would be accomplished
within ICAO ACP WG-M (DOC 9880), and/or RTCA
SC-214 SG-XX. Target Seg 2. - 2. Data Comm Subnetwork level list of
anticipated standards modifications/additions - Due to changes to the implementation
characteristics of VDL Mode 2 within AEEC 631, it
will be necessary to bring such changes forward
to ICAO ACP WG-M for incorporation and acceptance
in the ICAO VDL Mode 2 Technical Manual and VDL
Mode 2 SARPS. This harmonization of changes
support programs such as Link 2k and Data Comm.
Target Seg 1, and Seg 2 - VDL Mode 2 Autotune requirements/characteristics
updates - Target Seg 1, and Seg 2. - VDL Mode 2 Frequency Support List-based handoffs
- Target Seg 1, and Seg 2. - VDL Mode 2 Frequency Management for multiple
frequencies - Target Seg 1, and Seg 2. - VDL Mode 2 protocol cleanup related to above
changes - Target Seg 1, and Seg 2. - Overall harmonization of AEEC 631 implementation
characteristics with ICAO VDL Mode 2 Technical
Manual - Target Seg 1, and Seg 2.
