12
ETFMS - PROCESS (2)
●
Adaptations, if any, in ATC systems
● Purchase and installation by NM (CFMU) of EN
●
Validation of received data (CPRs) in NMOC (CFMU) test
system
●
Move of received data (CPRs) to NMOC (CFMU) operational
system
●
FAM activation (after agreement with ANSP)

ETFMS - PROCESS (3)
CPR Operational Evaluation
● Provide live data to ETFMS Shadow/test system.
● NMOC (CFMU) Evaluates and provides evaluation
report to
ANSP.
● Improvements may be required.
● Go-No-Go decision.
● Agree date to send CPRs to ETFMS Operational system.
