User Input
Sustain voice communications in VHF Band as long as possible
Make optimum use of current equipage 8.33 kHz channel spacing is the preferred first
alternative only when current 25- kHz spectrum no longer meets operational needs
New technical solutions should be pursued only after all non-equipment solutions have been exhausted
Spectrum allocation Policies and procedures
Aeronautical Data Link System (ADLS) is important Use existing VHF capabilities / equipment
(VDM2, 1090 MHz, UAT) to provide ADLS until Future Communications Study decisions and milestones are set
Commit to a data link technology, schedule, and funding by 2007.
AOC should remain separate from ATS communication
Sustain voice communications in VHF Band as long as possible
Sustain future operation of voice communications in the VHF band
by expanding 8.33 services (vertical expansion and potentially into the upper VOR band)
Foresee a change in paradigm in the 2020 timeframe where additional capacity is provided by making data the primary mode of communications
Given this short timescale to develop and implement new technologies, a decision has to be made soon.
Target a global solution, but one that focuses on the requirements of the high-density core areas
Demonstrate a solid business case for the introduction of future systems
In the case of Satellite communications, consider options of having a dedicated ATM system vs. sharing the infrastructure with other services.
Facilitate the transition to a new system by considering the introduction of a digital voice service. This is a desirable step but not critical.
•Use VHF band and existing technologies and equipment as long as possible
• Prepare for digital communications to support anticipated shift in operational paradigm
•Ensure timely technology decisions
• Ensure solid business case for new technologies
• Ensure solutions resolve local issues, and are globally applicable
