MOBILE COMMUNICATIONS

Short-term trend is to extend VHF coverage by deploying remote VHF stations (Algeria, Egypt, ASECNA, etc.).

HF is still maintained in some areas, though it offers poor quality communications, as it is considered:

better than nothing outside VHF coverage areas,

cheap back-up to VHF in VHF coverage areas.

Provisions should however been considered for Satcom Voice services for non-routine COM in medium to long-term

REVENUES FROM COCKPIT (MOBILE) COMMUNICATIONS

DEFINITION OF HIGH REVENUES AREAS AND ROUTE SEGMENTS

Satellite-based ATS datalink services in AFI : should be mainly used along routes segments

with medium/high traffic and located in oceanic areas or in remote areas, where there are no or

limited radar / VHF coverage should include CPDLC and FIS services, plus ADS-C services where

no radar/ADS-B deployment has been implemented or is planned

Satellite-based ATS datalink services in MID: should be deployed and used all over Egypt and the Arabic

peninsula, should include only FIS and CPDLC services as the Radar coverage

will be almost complete in this area

Satellite-based AOC services in AFI/MID: are assumed to be used mainly over the routes segments and

areas where Satellite-based ATSC services are provided and used
