Abstract: A computer-implemented method for indicating damage to an aircraft, the computer-implemented method comprising: receiving data indicating an occurrence of damage to an aircraft and severity of the damage; determining information to present to an operator of the aircraft using the received data, the information being dependent on the severity of the damage; and controlling an output device to provide the determined information indicating the occurrence of damage to an operator of the aircraft.

Abstract: A system and a method for determining a high oil consumption in a gas turbine engine of an aircraft are provided. The method includes determining one or more engine and aircraft conditions. The one or more engine and aircraft conditions includes at least one of an oil quantity, an oil temperature, an oil pressure, an engine speed, an aircraft altitude, and an aircraft attitude. The method further includes determining a trend in oil conditions based on at least the one or more engine and aircraft conditions. The trend in oil conditions provides at least one of a rate of consumption of oil or a time duration of remaining oil. The method further includes determining the high oil consumption based on a comparison of the trend in oil conditions with a threshold or a comparison model.

Abstract: A computer-implemented method for determining damage to an aircraft, the computer-implemented method comprising: (i) receiving first data from a first sensor, the first data comprising values for a first parameter of an aircraft; (ii) determining whether damage has occurred to the aircraft using the values of the first data; (iii) receiving second data from a second sensor, the second data comprising values for a second parameter of the aircraft; (iv) determining whether damage has occurred to the aircraft using the values of the second data; and (v) controlling output of a signal comprising data indicating the occurrence of damage to the aircraft using an occurrence of damage determined at step (ii) and/or an occurrence of damage determined at step (iv).
