Recording of radar data as in Annex 11 paragraph 6.4.1
ICAO Annex 11 paragraph 6.4.1 states that radar data of primary, secondary, ADS shall be recorded and retained for a period of at least 30 days.
DSB states in the final report on MH17 that Russia does not comply to Annex 11 because they did not save primary radar recordings. Instead Russia handed over a video recording of primary and secondary radar recordings.
Does Russia indeed not comply? I have not found any rule which states the format of archiving.
