This chapter introduces rotorcraft steady-state flight performance and stability, and we explain key concepts of the conventional helicopter as well as other rotorcraft types (tandem helicopter and compounds). Numerical models of performance estimations are provided for level flight, climb-out, and descent. Stability issues presented include longitudinal/lateral trim and speed stability. Different take-off procedures are illustrated, alongside the certification requirements (Category A and B rotorcraft). There is further discussion of ground effects, such as lift augmentation and ground resonance. We provide examples of methods used to estimate the direct operating costs, which are one of the major limiters to the use of rotorcraft. We complete the performance analysis with fuel planning methods, payload-range assessment, and speed augmentation concepts (compound helicopters).
