The framework applies current, historical, predicted and forecasted weather data to the one or more operational rules governing a mission, a payload, a flight plan, a craft type, and a location of the mission for aircraft such as an unmanned aerial vehicle or remotely-piloted vehicle, and generates advisories based on the evaluation of flight conditions such as a mission compliance status, instructions for operation of unmanned aircraft, and management advisories. The flight condition advisories include either a “fly” advisory or a “no-fly” advisory, and the framework may also provide a mission prioritization and optimization system. ## Claims ### Claim 1 A method, comprising: ingesting, as input data, weather information, mission-specific flight parameters for an unmanned aircraft, and one or more operational rules for the unmanned aircraft, the weather information including at least one of current weather data, historical weather data, predicted weather data, and forecasted weather data for a specific geographic area, the mission-specific flight parameters defining a mission and including one or more of a payload, a flight plan, a craft type, and a geographical location of the mission, and the one or more operational rules at least relating to performance of the mission;
