  In the UAM space, strategic deconfliction provides an all-essential layer to
airspace automation by providing safe, pre-emptive deconfliction or assignment
of airspace resources to airspace users pre-flight. Strategic deconfliction
approaches provide an elegant solution to pre-flight deconfliction operations.
This overall creates safer and more efficient airspace and reduces the workload
on controllers. In this research, we propose a method that constructs routes
between start and end nodes in airspace, assigns a contract of operational
volumes (OVs) and ensures that these OVs are sufficiently deconflicted against
static no-fly zones and OVs of other airspace users. Our approach uses the A*
optimal cost path algorithm to generate the shortest routes between the origin
and destination. We present a method for generating OVs based on the
distribution of aircraft positions from simulated flights; volumes are
constructed such that this distribution is conservatively described.
