Claim:
1. A method suitable for use onboard an aircraft, executable by a processor, for selecting a runway for an aircraft, comprising: receiving, from a runway database, runway data for a first runway and a second runway; receiving, from a positioning subsystem, an aircraft position; receiving, from sensors, aircraft data comprising an aircraft heading relative to the first runway and an aircraft heading relative to the second runway; creating, for the first runway, a first boundary envelope surrounding the first runway, a second boundary envelope surrounding the first boundary envelope, and a third boundary envelope surrounding the second boundary envelope, each envelope having a predetermined number of points; creating, for the second runway, a fourth boundary envelope surrounding the second runway, a fifth boundary envelope surrounding the fourth boundary envelope, and a sixth boundary envelope surrounding the fifth boundary envelope, each envelope having a predetermined number of points; scoring the first runway, creating a first runway score, based on a combination of (i) the aircraft position with respect to the first runway, and (ii) a number of points associated with boundary envelopes surrounding the first runway within which the aircraft heading falls; scoring the second runway, creating a second runway score based on a combination of (i) the aircraft position with respect to the second runway, and (ii) a number of points associated with boundary envelopes surrounding the second runway within which the aircraft heading falls; and selecting the first or the second runway based on the first runway score and the second runway score.
