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
