6 Eurocontrol Eurocontrol Software Tools for Frequency Planning and Management 3 - MANIF Functions: 3 - MANIF Functions: ICAO COM tables import functions, Assignment database management, Polygon database management, Frequency compatibility check, Frequency search, Including Shifting existing frequencies Graphic display of coverage and protection areas.

7 Eurocontrol Eurocontrol Software Tools for Frequency Planning and Management 3 - MANIF Planning & Compatibility criteria: 3 - MANIF Planning & Compatibility criteria: MANIF Planning & Compatibility criteria in line with the EUR Frequency Management Manual that takes into account of : Coverage (including max FL) of the services (circ/sectors), i.e. DOC Power of desired and undesired transmitters, Frequency gap between desired and undesired services, Pairing (double/triple pairing : VOR-DME, ILS-DME, MLS- ME,… Harmonic level (used for VOR/VOR adjacent channel separation), Problems due to existence of unpaired DME or TACAN in the line of sight of an unpaired VOR.

9 Eurocontrol Eurocontrol Software Tools for Frequency Planning and Management PLANIFs Optimization Strategy: 1. A weight is given to each existing assignment => equal to the number of available frequencies => each existing assignment get an EASY or NONEASY status 2. Each Need is processed => Available frequencies => Weight => EASY or NONEASY status 3. Needs are processed from the most NONEASY to the EASIest 4 - PLANIF for the VHF block planning meetings 4 - PLANIF for the VHF block planning meetings

10 Eurocontrol Eurocontrol Software Tools for Frequency Planning and Management PLANIFs Optimization Strategy: 4. The "best" solutions are those corresponding to frequencies : => already used by another need, => with a minimum number of remaining needs capable to use the frequency, => implying a minimum of shifts. 5. New frequencies are searched for requested shifts (No shift for them). 6. If all requested shifts can not be satisfied, a "Feed-back" is done : => Unsatisfied shifts are considered as non shiftable and the planning process restarts from step PLANIF for the VHF block planning meetings 4 - PLANIF for the VHF block planning meetings
