Abstract
An emergency flight plan useable for an aircraft provided with a navigation system wherein the flight plan includes a pointer matrix including a number of cells. Each cell of the matrix has a unique identification and each cell corresponds to a geographical area, and wherein each cell of the matrix includes an identification of a cell corresponding to a next waypoint in an emergency route.
Claims21
An emergency flight plan useable for an aircraft provided with a navigation system, said flight plan comprising:
- a pointer matrix comprising a number of cells wherein each cell of said matrix has a unique identification and each cell corresponds to a geographical area, and wherein each cell of said matrix comprises an identification of a cell corresponding to a next waypoint in an emergency route.
A method for preparing an emergency flight plan for an aircraft, the method comprising:
- dividing a map of a geographical area into a grid forming cells;
- indicating identification of each cell;
- selecting termination points in an area of interest;
- and
- determining pointers of each cell that points to a cell using the indicating identification in order to set up an emergency route wherein all the pointers form said pointer matrix.
A method for emergency flight control of an aircraft, the method comprising:
- receiving an indication that a failure has occurred in the aircraft;
- determining a position of the aircraft in a geographical area, wherein said area is divided in a grid forming cells in which each is identified by a cell ID;
- determining the cell ID of the aircraft based on the position of the aircraft;
- retrieving from said cell ID of the aircraft a pointer where to direct the aircraft from said pointer matrix that corresponds to the grid of said area;
- and
- directing the aircraft to the cell ID that the pointer indicated.
An emergency travel plan useable for a vehicle provided with a navigation system, the travel plan comprising:
- a pointer matrix comprising a number of cells wherein each cell of said matrix has a unique identification and each cell corresponds to a geographical area, and wherein each cell of said matrix comprises an identification of a cell corresponding to a next waypoint in an emergency route.
A data structure useable as a precaution plan and as an emergency flight plan onboard an aircraft, said data structure comprising:
- a number of records, each record corresponding to a limited geographical area, and the records together covering an area of interest for an aircraft having a mission, wherein each record is capable of holding data representative an identification of a next waypoint in an emergency route.
