GUID:  {EBCD2F4F-3447-48a6-893A-68EE01D32172}

Assigns beacon codes to flights either automatically or through controller input.  Provides to Departure Clearance and Taxi functions.

2.4.13 [S2] Generate ATIS
Type:  Object   
Status:  Proposed.  Version 1.0.  Phase 1.0.
Package: 2.0 Ground Data Processing (GDP)     Keywords:  
Detail:  Created on 5/30/2007.  Last modified on.6/1/2007.
GUID:  {56EB4429-08E1-4b3f-947B-BB5E0C618300}

a) Create D-ATIS Reports for local airport/airspace, Manage adaptation information (altimeter settings, runway, frequencies) for inclusion in D-ATIS report.  Allow specialist to review and edit D-ATIS reports.

b)   Provides interface between ATIS voice radio and D-ATIS creation.  Provides voice synthesis and review of voice synthesis to ensure accuracy and “hearability” of information

c) Establishes connection with National Data Comm Function, which delivers the D-ATIS report.

c) Establishes connection with other systems that provide the airport or airspace status input data, e.g., ASOS, weather, altimeter settings, as needed.

2.4.8 [S2] Process CPDC Messages
Type:  Object   
Status:  Proposed.  Version 1.0.  Phase 1.0.
Package: 2.0 Ground Data Processing (GDP)     Keywords:  
Detail:  Created on 5/30/2007.  Last modified on.6/1/2007.
GUID:  {36E37754-C8B4-45b0-BC6B-B9CA206101C2}

The Controller Pilot Data Communications (CPDC) is the overall CPDC message generation function It formats messages based on protocol structures supported by ground users and aircraft avionics and enforces inter-process rules. 

This function manages data comm connections for Eligible Users.  Eligible users are ground users can be eligible users and only a SINGLE user is granted eligible access at a time.  Communication Eligibility is used to send clearances and instructions to aircraft.  Eligibility verification is handled by identifying/confirming the 'eligible' user with the correct FDP.
