Today's store separation analysis is more and more confronted to marginal clearance situations due to increasing requirements imposed by the aircraft operators. In fact, that an advanced missile has to be perfectly released during arbitrary aircraft maneuvers and variable installations affords the accurate knowledge of the missile's motion during tip-off. The engineering task is therefore no longer focussed exclusively on the analysis of safety aspects of separation, but is now to be extended on the consideration of compatibility between operator's requirements to allow any strength of release disturbances and the missile control system to overcome such situations. The results expected from such an analysis is an accurate indication of any marginal limitation respective to safety or to controllability. Based on simulations performed with a powerful 6-DOF code developed at MBB during the last decade, this paper deals with such inconsistancies implicated by excessive roll or pitch-motions during different rail-launch situations. After a short description of the basic algorithms, computed results involving data from flight test movie will be displayed by 3D-video, in order to prove that the problem area is well handled.
