A Commission proposal for a Council Directive on common frequency bands to be designated for the coordinated introduction of the terrestrial flight telecommunications system (TFTS) in the Community (COM(92) 314) notes that the European Telecommunications Standards Institute (ETSI) is currently developing the European Telecommunications Standard for the terrestrial flight telecommunications system and that this is expected to be approved during 1992. The European implementation of TFTS will provide a unique opportunity to establish European aeronautical public correspondence (a public telecommunications service in aircraft during flight). An early decision on TFTS frequency bands is hence essential to avoid a delay in the development of the standard in Europe, and to maintain the momentum currently achieved. It is proposed that Member States shall designate common frequency bands for TFTS by 1 January 1993. These shall be 1670-1675 MHz for the ground to air direction and 1800-1805 MHz for the air to ground direction and will become available as follows: The frequency spectrum allocated shall be 2x1 MHz with effect from 1993, 2x3 MHz with effect from 1994, 2x5 MHz with effect from 1998.
