An avionics system for an aircraft includes a threat data structure and a processor. The threat data structure stores an alert threshold and a margin threshold. The processor is programmed to: predict an aircraft state at a plurality of positions along a potential future trajectory; calculate a margin value at each of the plurality of positions as a difference between the predicted future condition and the threat value at each respective one of the plurality of positions; calculate a margin rate of change at each of the plurality of positions based on a change in the margin value along the potential future trajectory; estimate a time to go value based on a minimum calculated margin value and a maximum calculated margin rate of change among the plurality of positions; and command an indicator to alert the pilot in response to the time to go value reaching the alert threshold.
