1. A method for generating input information associated with a question relating to at least one of a situation analysis or choice of tactics to be provided to a simulation device so as to generate an answer to the question on-board a platform, the method comprising: electing said question to be answered by a simulation among a plurality of questions utilizing a communication unit configured to permit inputting of said elected question to the simulation device; inputting said elected question to the simulation device; determining with the simulation device depending on the inputted elected question a simulation criterion corresponding to said simulation based on one member of a group comprising real-time simulation, simulation comprising an estimation process, or simulation comprising a prediction process; copying with the simulation device a continuously updated environmental model comprising information relating to existing entities in an environment of the platform based on sensor data, upon inputting said elected question, wherein copying the continuously updated environmental model is performed depending upon a time when the elected question is inputted; preparing with the simulation device a simulation scenario by applying at least one default model to the entities of the copy of the environmental model, depending on said inputted elected question, wherein the at least one default model comprises at least one characteristic associated with representations of the entities; performing a matching procedure so as to identify the at least one default model based on measured sensor data and pre-stored sensor data in order to provide the environment model with information about different aircraft models; modifying with the simulation device the simulation scenario regarding the entities of the copy of the environmental model depending upon said inputted elected question; and generating with the simulation device the input information depending upon the inputted elected question, said input information comprising the modified scenario, and the simulation criterion so as enable generating the answer to the inputted elected question utilizing the simulation device on-board the platform, based on said generated input information.
