The results of the InterOp test 2013 concerning the new protocol SAC (Supplemental Access Control) are available. The test event was split into two slots – a conformity test (to test if the document conform to the latest ICAO standards) and a crossover test (to test, if each document can be read by the inspection system). A concluding test report is available here. Thanks to Mark Lockie and Michael Schlüter for organizing this successful event.
