3. Background
VDL Mode 2 Multi-frequency enhancements support NextGen and SESAR programs implementations
RTCA SC-214 VDLSG / EUROCAE WG-92 / AEEC DLK collaborated to update the VDL Mode 2 Standards to include the “multi-frequency” operation as established within the AEEC 631 Supplement 6 characteristics
Such Standards include:
AEEC 631-6
DO-224C (RTCA Minimum Aviation System Performance Standard)
DO-281B (RTCA Minimum Operational Performance Standard)
ED-92B (EUROCAE MOPS)
ICAO Doc 9776 VDL2 Technical Manual

4. ICAO Doc 9776 Edition 2 History
ICAO Doc 9776 Amendment Proposal (AP #310) was initiated in WG-M/17 (Feb 2011)
EUROCONTROL reported VDL2 multi-frequency validation activities and results (IP5, IP6 and IP7) in WG-M/18 (July 2011)
Based on validation results, and RTCA/EUROCA/AEEC further review of AP #310, an update to this amendment was necessary This was presented at WG-M/19 (June 2012), and accepted
AP #310 was incorporated into ICAO Doc 9776 to produce an “Edition 2” final draft
Edition 2 was submitted and presented to ICAO ACP in the WG-M/20 meeting (January 2013)
At this meeting, the WG-M committee recorded meeting minutes, which suggested that ICAO would begin its publication process for Edition 2 of ICAO Doc 9776
The meeting minutes also noted that supportive validation material towards the Edition 2 modifications (specifically for the addition on multi-frequency) would be beneficial towards the publication approval process

5. ICAO Doc 9776 Edition 2 publication plan
A validation activity summary letter was created in support of the Edition 2 approval process (reviewed 7/2013 AEEC DLK Seattle meeting)
Such a letter was submitted to ICAO, which also included the supportive validation material towards the Edition 2 modifications
Most recent correspondence from ICAO indicates a publication target of ICAO Doc 9776 Edition 2 to be 3rd Quarter of this year
