Abstract
The T-33 variable stability and variable drag airplane was used in a flight program to evaluate various longitudinal short period characteristics at each of four drag configurations for the landing approach task. Pilot rating and comment data were collected and used to determine short period requirements for the landing approach task. The importance of the slope of the thrust required vs. velocity curve is discussed and related to pilot comments and control difficulties. The longitudinal control gain selected by the pilot was a function of short period frequency and damping ratio. Curves relating control authority and short period frequency and damping ratio are derived from these data. The power spectral density of the pilot's elevator stick motion was found to be significantly affected by short period dynamics and atmospheric turbulence.
