unusual  design feature when compared to the state of technology envisioned in  the 
airworthiness standards for transport -category airplanes. This  design feature is the 
installation of a system that allows connection  to airplane electronics and n etworks, and 
access from aircraft external  sources (e.g., operator networks, wireless devices,
