AIRPLANE RESPONSE AND CLOSED-LOOP CONTROL 623
6.6 Summarlt .
In this chapter, we have studied the longitudinal and lateral-directional responses
of the airplane. The longitudinal response of a statically stable airplane consists
of two distinct modes, the short-period mode and the phugoid mode. The lateral-
direction motion comprises roll~subsidence mode, the Dutch-roll oscillation, and
the spiral modes. Accordingly, we obtained simplified transfer functions and state-
space models to study these modes individually. These simplified transfer functions
