Flight formations of unmanned aerial vehicles may require coordinated motion in pitch for such tasks as terrain tracking. They maintain a constant altitude over varying terrain elevations and may assist collision avoidance where an altitude change is needed rather than a lateral change. In these maneuvers, controller ability to adjust relative altitude positions (as attractions and repulsions) of the aircraft subject to stability constraints that ends up in a formation shape should be demonstrated. The ascent and descent flight control mode combinations of each unmanned aerial vehicle participating in the formation generally offer the attractions and repulsions. In this paper, centralized and decentralized controller abilities to develop a cooperative formation with flight control modes made of transients and steady states are presented by using two and more than two homogenous unmanned aerial vehicles. A challenge in presenting such a formation by using a centralized controller is its design itself. Generally, eigenstructure properties depict flight control mode variations. That is, variations in closed-loop poles offered by a structurally varying centralized controller compatible to its reconfigurable communication patterns are sufficient to capture the flight control mode options. Hence, a procedure to design such a controller using real parameters is presented.
