Abstract

A wake turbulence avoidance light system is provided including an aircraft runway with a periphery including a pair of long parallel side edges and a pair of short end edges. Also included is a plurality of light assemblies mounted along at least one of the side edges of the runway in spaced relationship. A plurality of sensors are adapted for indicating a point on the runway at which a plane has departed. Finally, control circuitry is connected between the light assemblies and the sensors for indicating a location of the point by illuminating a light assembly adjacent thereto, as detected by the sensor.

Claims

1. A wake turbulence avoidance light system comprising:

an aircraft runway with a periphery including a pair of long parallel side edges and a pair of short end edges;

a plurality of light assemblies mounted along at least one of the side edges of the runway in spaced relationship;

a plurality of sensors for indicating a point on the runway at which a plane has departed; and

control circuitry connected between the light assemblies and the sensors for indicating a location of the point by illuminating one of the light assemblies adjacent thereto, as detected by the sensor.

2. A wake turbulence avoidance light system as set forth in claim 1 wherein the sensor is a motion sensor.

3. A wake turbulence avoidance light system as set forth in claim 1 wherein the motion sensor is triggered upon the aircraft rolling over the same.

4. A wake turbulence avoidance light system as set forth in claim 1 wherein the lights are situated on both sides of the runway and are visible only from one end edge of the runway.

5. A wake turbulence avoidance light system as set forth in claim 1 wherein the control circuitry includes a reset switch for deactivating all of the light assemblies upon the manual closing thereof.

6. A wake turbulence avoidance light system as set forth in claim 1 wherein the control circuitry includes a plurality of set switches each adapted for illuminating at least one associated light assemblies upon the manual closing thereof.

7. A new and improved wake turbulence avoidance light system comprising:

an aircraft runway with a periphery including a pair of long parallel side edges and a pair of short end edges;

a plurality of light assemblies mounted along the side edges of the runway in equally spaced relationship along an entire length thereof, each light assembly including a vertically oriented post, a dome-shaped transparent housing mounted on a top end of the post, and a lamp mounted within the housing, the light assemblies grouped into laterally aligned pairs each adapted to illuminate upon the receipt of power, wherein the housings of the light assemblies of a first side edge of the runway are visible only from a first end edge of the runway and those of a second side edge of the runway are visible only from a second end edge of the runway;

a plurality of motion sensing strips each extending laterally between the side edges of the runway between an associated pair of the light assemblies, each motion sensing strip adapted to deploy an activation signal upon the same being depressed by a wheel of an aircraft; and

control circuitry connected between each pair of the light assemblies and the associated motion sensing strips, the control circuitry adapted to illuminate each pair of light assemblies from the associated motion sensing strip and further deactivate the remaining light assemblies upon the receipt of the activation signal, the control circuitry further including a reset switch for deactivating all of the light assemblies upon the manual closing thereof and further a plurality of set switches each adapted for illuminating an associated one of the pairs of light assemblies upon the manual closing thereof.
