24F. In your personal opinion, could the
following security failures during flight
potentially result in major (or greater)
safety failures to that aircraft: The
identities of passengers and crew onboard
the aircraft become known to
unauthorized hostile entities?
24G. In your personal opinion, could the
following security failures during flight
potentially result in major (or greater)
safety failures to that aircraft: The
current location of the aircraft is
accurately tracked in real time by
unauthorized hostile entities?
24H. In your personal opinion could the
following security failures during flight
potentially result in major (or greater)
safety failures to that aircraft: The
authentication infrastructure (e.g., Public
Key Infrastructure) used by the NAS
becomes maliciously compromised so
that it is no longer trustworthy?
25. Have you designed or deployed, or
do you currently plan to design or deploy,
LANs onboard aircraft?
