Hey chaps,

My company provides info whether the airport uses DCL or PDC. But what are precisely the differences. Jepp text gives little info.

Same thing. Departure Clearance (DCL) over most of the World, Pre-Departure Clearance (PDC) in America.

DCL is a clearance direct from ATC sent to your ACARS and does not require a read back on clearance delivery.
PDC comes from a different source and requires a PDC read back on clearance delivery.

oz in dxb, disagreed. Never read back a PDC unless specifically instructed to do so, mostly in China. There's an acceptance function with confirmation.

Applicable to Operators affected by the European Data Link Services Implementing Rule

on this accord I wonder how some operators intent to accomplish read backs for:
Some Operators may have received an email signed by Eurocontrol and DFS Deutsche Flugsicherung in mid July 2012 (Refer to Eurocontrol e-mail) about changes in CPDLC operations over Maastricht and Karlsruhe Upper Airspace Controls (UACs). These changes are:

The discontinuation of the Voice Read Back (VRB) procedures from November 15, 2012. This requires Protected Mode CPDLC (PM-CPDLC) capable avionics. Aircraft without PM-CPDLC (Refer to Note 2 below) will not be able to log on to ATC centers via datalink.
The requirement to fill in the 24-bit address in the Filed Flight Plan (FPLN) from September 27, 2012. The 24-bit address is also called the Mode S address, aircraft address, or aircraft ICAO code.
Interesting times no more chit chat with the boys on the ground, nor everywhere yet but it's coming.
