Abstract: One example of an aircraft tail strike detection and prevention system can include one or more processors that obtain one or more aircraft characteristics representative of an aircraft flying toward a landing location and one or more external characteristics representative of one or more conditions outside of the aircraft. The one or more processors can obtain a current descent trajectory that the aircraft is to follow to land at the landing location and calculate a probability that the aircraft will experience a tail strike upon touchdown based on the one or more aircraft characteristics and the one or more external characteristics. The one or more processors can alert a pilot of the aircraft that the aircraft will experience the tail strike upon touchdown based on the probability.

Abstract: A system and a method include a user interface including a display and an input device. The input device is configured to be operated to provide parameters for a flight of an aircraft. A control unit is in communication with the user interface. The control unit is configured to receive the parameters from the user interface, and determine one or both of emissions of the aircraft during phases of the flight of the aircraft, or emissions costs for the flight of the aircraft.

Abstract: A method for operating an aircraft to reduce an emission level. The method comprises monitoring an emission level of the aircraft during a flight. The method further comprises detecting that the emission level exceeds an emission level threshold. In addition, the method comprises changing one or more operational settings of the aircraft during the flight and reducing the emission level during the flight to below the emission level threshold.
