ATFCM

PRE-TACTICAL PHASE

Pre-Tactical Flow Management is applied during six days prior to the day of operation and consists of planning and coordination activities

This phase analyses and decides on the best way to manage the available capacity resources and on the need for the implementation of flow measures (regulations or routings). The output is the ATFCM Daily Plan (ADP) published via ATFCM Notification Message (ANM) and

Network News

TACTICAL PHASE

Day of flights

There are organizational and operational actions for ATFCM

This phase is mostly performed in real-time mode. Tactical phase focused on solution of current problems, revealing of overloaded areas and undertaking measures

CFMU may monitor TACT system for reveling of capacity excess (not identified at pre-tactical phase) and for revealing of capacity reserves, which may be used to decrease number of ACFT in overloaded areas

TACTICAL PHASE

Tactical Flow Management is applied on the day of the operation. This phase updates the daily plan according to the actual traffic and capacity

The management of the traffic is made through slot allocation and/or ad-hoc rerouteings

CASA

CASA – fully automated system, whish is created to distribute SLOTs. This system never prefers some AO

FMD takes decision to activate regulation in certain airspace areas after consultations with appropriate FMP.

Then the TACT sets defined area, beginning and end of regulation, flow entry parameters, etc.

System regulates all flight, which are intended to enter this airspace, their sequence and other parameters
