AVIONIC DISPLAY SYSTEMS AND METHODS FOR GENERATING VERTICAL SITUATION DISPLAYS INCLUDING INSTABILITY PREDICTION AND AVOIDANCE SYMBOLOGY

Avionic display systems (10) and methods (40) are provided for generating avionic displays (28) including instability prediction and avoidance symbology (32, 68, 70, 72, 84, 86), such as dynamically-adjusted drag device deployment cues (32). In one embodiment, the avionic display system includes a controller (12) and an avionic display device (14) on which an avionic display, such as a Vertical Situation Display (VSD), is generated. The controller is configured to: (i) project (46) 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 (48, 50) whether implementation of an optimized drag device deployment scheme can prevent the projected unstable aircraft state; and (iii) if implementation of the optimized drag device deployment scheme can prevent the projected unstable aircraft state, generating (52) symbology on the avionic display indicative of the optimized drag device deployment scheme.
