This chapter introduces the basic concepts for steady flight based on certain clearly stated assumptions. Answer the following questions by describing how the development in this chapter would need to be modified based on the indicated change in the assumptions. Which equations would need to be modified? Give a brief description of the required modifications of the equations.
(a) Suppose that the aircraft is in steady flight and the atmosphere is not stationary. What modifications would need to be made to the development?
(b) Suppose that the aircraft is in steady flight and the Earth is assumed to be spherical. What modifications would need to be made to the development?
(c) Suppose that the aircraft is in steady flight and the Earth is assumed to be spherical and rotating. What modifications would need to be made to the development?
(d) Suppose the aircraft is in steady flight and the decrease in the weight of the aircraft as fuel is burned is taken into account in the analysis. What modifications would need to be made to the development?
