Abstract
A method and system for locating aircraft with respect to airport runways selecting as a function of aircraft state parameters one of a plurality of candidate runways that the aircraft on which it is installed is most likely to encounter, whether taxiing, preparing for take-off, or approaching to land.

47. A runway selection computer program residing on a computer usable storage medium, the computer program comprising:
-
computer-readable program code means for receiving one or more signals representative of current position, orientation and phase of flight information of an installation aircraft;
computer-readable program code means for accessing stored runway survey information as a function of the current aircraft position information; and
computer-readable program code means for selecting a runway as a function of the current aircraft position, orientation and phase of flight information and the runway survey information, including;
computer-readable program code means for determining a plurality of runways nearest the current position of the installation aircraft;
computer-readable program code means for constructing a runway envelope relative to each of the runways; and
computer-readable program code means for determining a presence of the aircraft within one of the runway envelopes by;
comparing at least the current aircraft position information with each of the runway envelopes, and determining coincidence of the position information with the runway envelope. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69)

70. A computer program product, comprising:
-
a computer-usable medium having computer-readable code embodied therein for configuring a computer processor, the computer program product comprising;
computer-readable code configured to cause a computer processor to receive at intervals samples of one or more instrument signals reporting updated flight parameter information;
computer-readable code configured to cause a computer processor to retrieve survey information about one or more candidate runways;
computer-readable code configured to cause a computer processor to generate at intervals and as a function of the updated flight parameter information an augmentation envelope around each of the one or more candidate runways, one of the augmentation envelope at least encompassing one of the candidate runways;
computer-readable code configured to cause a computer processor to compare a current aircraft position with the augmentation envelope corresponding to each of the candidate runways; and
computer-readable code configured to cause a computer processor to determine as a function of the comparison a coincidence of the current aircraft position with the augmentation envelope corresponding to one of the candidate runways. - View Dependent Claims (71, 72, 73, 74, 75, 76, 77, 78)

79. A system for selecting one of one or more candidate runways, the system comprising:
-
means for identifying one or more runways as a function of a current position of an aircraft, means for constructing an augmentation envelope relative to each of the one or more runways that at least encompasses the corresponding runway; and
means for determining as a function of the aircraft position an encounter of the aircraft with one of the augmentation envelopes. - View Dependent Claims (80, 81, 82, 83, 84, 85, 86, 87, 88, 89)

90. A runway selection apparatus, comprising:
-
a database of runway survey data;
a processor structured for receiving samples of one or more signals reporting a plurality of different aircraft state parameter data and for retrieving runway survey data from the database; and
one or more algorithms executable by the processor for selecting one of a plurality of different runways as a function of one or more of the aircraft state parameter data and the retrieved runway survey data, the one or more algorithms comprising;
one or more algorithms for constructing an augmented runway envelope corresponding to each of one or more candidate runways, and one or more algorithms for comparing with one or more of the augmented runway envelopes a current position of an aircraft having the apparatus installed thereon. - View Dependent Claims (91, 92, 93, 94, 95, 96, 97, 98, 99, 100)
