E) EGLL WILL OPERATIONALISE AN AUTOMATIC DATA EXCHANGE WITH NETWORK
OPERATIONS TO BECOME AN ANI (ADVANCED NETWORK INTEGRATED) AIRPORT,
IN ADDITION TO THE EXISTING ACDM (AIRPORT  COLLABORATIVE DECISION
MAKING) MESSAGE EXCHANGE. AN ANI AIRPORT HAS FULLY ADOPTED THE
AIRPORT-CDM CONCEPT BY PROVIDING THE FULL SET OF DPI MESSAGES
(DEPARTURE PLANNING INFORMATION  P-DPI, E-DPI, T-DPI-T, T-DPI-S,
A-DPI AND C-DPI) AND ALSO PROVIDES G-API MESSAGES (GENERAL ARRIVAL
PLANNING INFORMATION) TO NETWORK MANAGEMENT OPS CENTRE (NMOC). WITH 
THE INTRODUCTION OF P-DPI AND G-API MESSAGE EXCHANGE WITH NM 
SYSTEMS, THE ATFM NETWORK MAY BE IMPACTED AS EARLY AS 48HR BEFORE 
EOBT. ACFT OPERATORS AND GROUND HANDLERS ARE REMINDED TO KEEP TARGET 
OFF BLOCK TIME (TOBT) AND EOBT UP TO DATE IN LINE WITH A-CDM 
PRINCIPLES. QUESTIONS MAY BE DIRECTED TO AOP(AT)HEATHROW.COM
