Graph theory is used to investigate three different problems arising in air traffic management. First, using a polynomial reduction from a graph partitioning problem, it is shown that both the airspace sectorization problem and its incremental counterpart, the sector combination problem are NP-hard, in general, under several simple workload models.
The graph and matrix theory helps to ensure the effective, safe, economic and ecological air traffic flow management, optimize the tactical flight planning, minimize the unexpected situations and prevent the possible air traffic congestions and delays.

Graph theory provides many useful applications in Operations Research. A graph is defined as a finite number of points (known as airports or vertices) connected by lines (known as edges or arcs). In this paper for a given graph find a minimum cost to find the shortest path between two airports. Figure 2.
Longitudinal, Lateral, and Vertical Axis. The longitudinal axis is an imaginary line running from the nose to the tail of the aircraft; motion about this axis is called "roll," controlled by the ailerons. Longitudinal stability is the tendency of an aircraft to return to the trimmed angle of attack.
