Runway occupancy monitoring and warning
First Claim
1. A method comprising:
- defining a zone on a runway at a region of ingress and egress for the runway;
monitoring the zone via at least one sensor to determine whether the zone is activated; and
providing an indication of runway occupancy to an airplane on final approach to the runway based on the determination.

Abstract
Techniques are described for monitoring runway occupancy and providing an indication of occupancy of a runway to an airplane on final approach the runway. A system, for example, defines and monitors one or more zones on the runway to determine whether the runway is occupied. Such a system includes sensors, such as inductive loop sensors, that may be located proximate to or on the runway, and the system may monitor ingress and egress of objects, such as airplanes or other vehicles on the ground, into and out of the zone in order to determine whether the zone is activated. The sensors may be located at points of entry and exit for the zone. The zones may be located at take-off hold areas of the runway and intersections of the runway with taxiways. A ground-based approach light array of the system may provide the indication of runway occupancy to the airplane.

37. A computer-readable medium comprising instructions that cause a processor to:
-
monitor a zone defined on a runway at a region of ingress and egress for the runway via at least one sensor to determine whether the zone is activated; and
provide an indication of runway occupancy to an airplane on final approach to the runway based on the determination. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46)

47. A method comprising:
-
defining a point of entry and a point of exit for a zone on an airport runway;
locating at least one activation sensor at the point of entry and at least one deactivation sensor at the point of exit for the zone;
sensing the ingress of objects to the zone via the activation sensor and the egress of objects from the zone via the deactivation sensor;
determining whether the zone is activated based on the sensed ingress of objects into and egress of objects from the zone; and
providing an indication of runway occupancy to an airplane on final approach to the runway via a ground-based approach light array based on the determination. - View Dependent Claims (48, 49, 50, 51, 52)

53. A system comprising:
-
an activation sensor located proximate to an entry point for a zone on a runway;
a deactivation sensor located proximate to an exit point for the zone;
a ground-based light array; and
a controller coupled to the sensors to sense the ingress of objects into the zone via the activation sensor and egress of objects from the zone via the deactivation sensor, wherein the controller determines whether the zone is activated based on the sensed objects, and provides an indication of runway occupancy to an airplane on final approach to the runway via the light array. - View Dependent Claims (54, 55, 56, 57, 58)
