1.1 The purpose of this AIP Supplement is to inform aircraft operators about the operation of the Departure Clearance (DCL) service using datalink at the following airport, effective from 12 MAY 2026:

2.1 The Departure clearance DCL using datalink is a digital messaging system used as mean of communication between ATC and Pilots for Clearance delivery. It is used as an alternative or backup to VHF voice communication for non-urgent or time-critic a communication. It is expected that the DCL will enhance the current clearance delivery service at Dammam, Abha, Jeddah, Riyadh, Gassim and Madinah Towers. 2.2 The Departure clearance (DCL) function is integrated into the ATM/EFIS system deployed at ATC Towers and has the capabilities to exchange datalink messages with FANS 1/A+ equipped aircraft. The processing of messages is achieved by the Air-Ground datalink processing (AGDLP) and the Flight data processing (FDP) function. The DCL function is compliant with ED-85A specification (ED-85A-datalink Application system document (DLASD) for DCL datalink service).

3.1 The DCL service will be available from the moment the datalink communication is established (LOGON) for clearance delivery until the time the aircraft starts taxiing. When the aircraft is taxing, ATC clearance revision will only be using VHF communication. 3.2 The DCL service will be initiated on Pilot DCL request, preferably before the Estimated off block time (EOBT).

4.1 To access DCL service, the following AFTN LOGON addresses should be used depending on the Airport of departure:

5.1 DCL services will be operational at Abha, Jeddah, Riyadh, Dammam, Gassim, and Madinah from 12th May, and will continue until the publication of GEN 3.4 (Communication Services) and AD 2.22 sections.

This AIP Supplement will remain valid until the information is superseded or incorporated into the AIP KSA.
