You can still block your N-Number — maybe

The FAA has issued a Q&A document to help explain which airplane owners can continue to block display of their flights after the Blocked Aircraft Registration Request (BARR) program ends later this year, according to a report by Mac McClellan at EAA.org. Only those who are able to “certify” that a “Valid Security Concern” exists will be allowed to block the tracking of their flights by N number on Internet sites that are available to anyone in the world.
