The present document is designed to ensure that equipment certified to it will be compatible with the relevant ICAOVDL SARPs [i.2] and ICAO VDL4 Technical Manual [i.1].

NOTE: In clause 5.1.4, Tertiary time, as described by the ICAO VDL4 Technical Manual [i.1], has not beenincluded as a requirement in the present document due to the opinion of the ETSI Working Group thatinsufficient evidence was available to be able to verify correct operation of a "floating network" ofstations operating on tertiary time.

Manufacturers should note that in future the tuning range for the transmitter and the receiver may cover any 25 kHzchannel from 108,000 MHz to 111,975 MHz.

The present document applies to "aeronautical mobile (airborne and in some cases ground vehicles)" equipment whichwill hereinafter be referred to as "mobile" equipment.
