The national airspace (NAS) will rapidly evolve in the next ten to twenty years.
Plans for Advanced Air Mobility (AAM) during that period envision highly
automated airspace management systems and electrically powered vehicles. AAM
concepts also anticipate limited human roles. The goal of limiting the human role
is to minimize the potential for misadventures, yet how the human role is limited
needs to be carefully considered in order to also preserve the potential for human
successes. The field of resilience engineering (RE) focuses on how systems can
change in order to seize an opportunity or withstand an unforeseen challenge. RE
methods rely on the use of empirical data to optimize the ability of any system to
adapt. RE studies have shown how individual and team initiatives ensure resilient
system performance by creating safety through flexibility. Benefits of the RE
approach include improved awareness of operational circumstances and how
system elements depend on each other, and the ability to allocate limited
resources and prepare for surprise. RE offers the ability to account for and
incorporate the human role as an essential element in order to ensure NAS
systems’ resilient performance. Data on the human contribution to safe and
resilient system performance, which is termed “work as done,” are available but
are not being considered as the NAS evolves. We present an approach that
describes how use of RE can enable the evolving NAS to adapt, and perform, in a
resilient manner. |
