Vehicular approach guidance method and system
First Claim
1. A guidance system for guiding a vehicle into an approach corridor relative to a landing zone, comprising:
- a first pair of guidance light units near the landing zone, each of the first pair of guidance light units having an affirmative color light segment and a negative color light segment, the affirmative color light segments from the first pair of guidance light units defining a first guidance corridor having first guidance corridor boundaries; and
a second pair of guidance light units near the landing zone, each of the second pair of guidance light units having an affirmative color light segment and a negative color light segment, the affirmative color light segments from the second pair of guidance light units defining a second guidance corridor having second guidance corridor boundaries projecting outwardly from the first guidance corridor boundaries to define angles between the first and second guidance corridor boundaries.

Abstract
A method and system for visually guiding a vehicle to an approach corridor and subsequent landing, parking, or docking zone. As a vehicle approaches the designated landing, parking, or docking zone, the pilot is visually guided into the approach corridor by one or more pairs of guidance light units. Each guidance light unit has at least an affirmative color light segment and a negative color light segment. The affirmative color light segment indicates affirmative approach, landing, parking, or docking conditions and the negative color light segment indicates negative approach, landing, parking, or docking conditions. The colored light segments of the guidance light units are positioned and oriented such that the affirmative color light segment either corresponds with the approach corridor or provides visual guidance to assist the pilot in guiding the vehicle into the approach corridor by defining outwardly extending guidance corridors. In addition to defining an approach corridor or outwardly extending guidance corridors, the guidance light units may be used to provide landing, parking, or docking zone information or vehicle position or attitude information relative to the approach corridor or landing, parking, or docking zone.
