An aircraft mission computing system, comprising:

• a computing engine configured to compute paths of the aircraft during a mission, the computing engine being configured to compute a given path of the aircraft during the mission based on operational mission specifications,
• a mission deck comprising a display and a display manager configured to display, on the display, at least one definition button for definition of at least one of the operational mission specifications, the at least one definition button being configured to be actuated by a user to define a choice of the at least one operational mission specification from among a plurality of choices for the at least one operational mission specification;
• the computing engine being configured to be activated after defining the choice of the at least one operational mission specification using the at least one definition button to determine at least one possible path of the aircraft based on the choice of the at least one operational mission specification defined by the user using the at least one definition button;
• the display manager being configured to display, on the display, after the activation of the computing engine, at least one outcome indicator providing feasibility information of the mission with the mission respecting the choice of the at least one operational mission specification defined by the user using the at least one definition button.
