Method and apparatus for displaying aircraft engine characteristics

A computer-implemented method for displaying information corresponding to the operation of an aircraft engine, comprising:

• receiving a plurality of signals corresponding to a plurality of engine operating parameters;
• determining if the engine operating parameters are within corresponding ranges of values;
• and
• if all the engine operating parameters are within the corresponding ranges, directing the display of a single qualitative visual cue indicating an overall operational state of the aircraft engine.

A computer-implemented method for displaying information corresponding to the operation of an aircraft engine, comprising:

• receiving at least one signal corresponding to at least one engine operating parameter;
• determining an overall operational state of an aircraft engine based at least in part on the at least one engine operating parameter;
• and
• directing the display of a single qualitative visual cue that indicates the overall operational state and the need for a crew action.

A method for displaying information corresponding to the operation of an aircraft engine, comprising:

• directing the display of an icon that indicates a qualitative overall operational state of the aircraft engine, the overall operational state being determined from at least one engine operating parameter;
• directing a change in the display of the icon when the overall operational state of the aircraft engine changes from a first overall operational state to a second overall operational state;
• and
• when the overall operational state of the aircraft engine is at least one of the first and second overall operational states, directing a display corresponding to a crew instruction.

A method for displaying aircraft engine information, comprising:

• receiving signals corresponding to a plurality of engine operating parameters;
• determining whether or not all the engine operating parameters are within corresponding parameter ranges;
• directing the display of a graphical icon representing an aircraft engine and indicating a qualitative overall operational state of the aircraft engine, the overall operational state being determined from the plurality of engine operating parameters;
• directing a change in the display of the icon when the overall operational state of the aircraft engine changes from a first overall operational state to a second overall operational state, wherein the change includes changing a color of the icon from a first color to a second color different than the first color, and wherein the engine is not running when the overall operational state is the first overall operational state, further wherein the engine is running within normal limits when the state is the second overall operational state;
• changing a color of the icon to a third color when the overall operational state of the aircraft engine changes to a third overall operational state in which the aircraft engine is operating with a malfunction that requires a reduction in engine power;
• and
• changing a color of the icon to a fourth color when the overall operational state of the aircraft engine changes to a fourth overall operational state in which the aircraft engine is operating with a malfunction that requires the aircraft engine to be shut down.

A computer-implemented method for displaying aircraft engine information, comprising:

• directing the display of an icon that indicates a qualitative overall operational state of an aircraft engine, the overall operational state being determined from a plurality of engine operating parameters;
• directing the display of an indication of thrust produced by the aircraft engine, the indication of thrust being different than the icon;
• and
• directing a change in the display of the icon when the overall operational state of the aircraft engine changes from a first overall operational state to a second overall operational state.
