Atransport aircraft whose wing span is 35.8 m is flying at 262 kts at an altitude where the lateral relative density parameter i2= 24.4. the dimensionless controls-fixed lateral directional characteristic equation is 4 5.8 20.32 + 79.0 0.37 = 0 (a) what can be deduced about the lateral-directional stability of the aircraft from inspection of the characteristic equation? (b) solve the characteristic equation approximately; determine estimates for the time constants of the nonoscillatory modes and the frequency and damping ratio of the oscillatory mode (c) comment on the acceptability of this aircraft
