We consider the fundamentals of the energy-based approach to spatial motion control. The resulting energy balance equation establishes quantitative relations between all energy sources and consumers in the system of objects “flying vehicle—thrust system—external environment.” We establish the structure and further modification of an energy-based flight control system. The energy balance equation lets us estimate the level of atmospheric disturbances and formulate the commanding control index for engine thrust under winds of complex structure. For ground-based stages, we show a prediction method for the takeoff energy possibilities with air traffic obstacles; for situations of interrupted takeoff, the possibilities to stop inside the runway.
