What is the FMG

A European Air Navigation Planning Group (EANPG) sub-group where frequency/spectrum management experts can:- Undertake Work related to European

frequency management Undertake Work related to ICAO spectrum

management Undertake other specific tasks as directed

by the EANPG

ACD A00000 00-01

What is the Role and Responsibilities of the FMG

The development of planning criteria for use within EuropeBased on ICAO Annex 10 guidance material with regional variations

The maintenance of a frequency assignment database for Europe

The co-ordination, against agreed criteria, of changes to the frequency assignment database

ICAO European spectrum management

ACD A00000 00-01

Why Does Europe Need an FMG

Complexity of Planning Issues Number of Large Airports

5 of the worlds top 20 within 600km of Luxembourg

Proximity of States11 States within same 600km radius of Luxembourg

Number of Assignments 12,000 VHF Comms 10,200 Nav Assignments(2100 NDB, 1200 Loc, 1500 ILS, 1000 VOR, 3400 DME, 1000 MLS)

Number of Co-ordinations2003 (488 VHF Comms, 68 NDB, 41 ILS, 3 GBAS,

41 VOR, 101 DME & 3 MLS)
