Abstract: The analysis of the linear model longitudinal motion airplane transients generated after the pilot bail-out is presented in this paper. The analysis object is the piston engine primary trainer airplane „Lasta“. The analyzes objective is the verification of the critical flight parameters in the preparation of the bail-out in-flight testing. The tools applied in the analysis are the combination of the in-house developed software for the airplane dynamic and control system design, used for the flight path and linear model parameters determination as well as the packadge used for linear system simulation. The analysis procedure applied throughout extensive range of flight data of interest is presented by the representative example.

Keywords: Airplane dynamic, Linear system, Motion transients, Pilot bail-out.
