Abstract: Avionic display systems and methods are provided for generating avionic displays including instability prediction and avoidance symbology, such as dynamically-adjusted drag device deployment cues. In one embodiment, the avionic display system includes a controller and an avionic display device, which is coupled to the controller and on which an avionic display, such as a Vertical Situation Display (VSD), is generated. The controller is configured to: (i) project whether an unstable aircraft state will occur during an approach flown by an aircraft; (ii) when an unstable aircraft state is projected to occur, determine whether implementation of an optimized drag device deployment scheme can prevent the projected occurrence of the unstable aircraft state; and (iii) if determining that the implementation of the optimized drag device deployment scheme can prevent occurrence of the projected unstable aircraft state, generating symbology on the avionic display indicative of the optimized drag device deployment scheme.
