Functional and energetic issues of control of feeder-airship of MAAT system are considered in the paper. MAAT (Multibody Advanced Airship for Transport) [1,2] is an environmentally friendly system for transportation of passengers and cargos. It consists of cruiser and a few feeders. Cruiser flies in stratosphere at almost fixed altitude. Feeder acts like an elevator, it delivers passengers and cargos from airport to cruiser and in opposite direction. Paper shows, that wide altitude range feeder flies through, strong and dynamic wind loads at various tropospheric and stratospheric altitudes, makes definition of control strategies and energy requirements for control a nontrivial task. That is why this work pays much attention to assessment and mathematical description of feeder flight environment, existing and potential wind profiles, essentially influencing at feeder flight trajectory. Energy efficiency increase is considered in the paper.
