Abstract

An anti-collision system is provided to enhance the conspicuousness of an aircraft to a second aircraft presenting a collision threat. When the computer of an airborne Traffic Collision Avoidance System (TCAS) designates a second proximately located aircraft as a collision threat a traffic advisory is issued. A light controller responds to a traffic advisory signal from the TCAS computer by illuminating one or more of the aircraft'"'"'s external lighting systems. TCAS II systems can also issue resolution advisory when the intruder poses a more immediate threat. A resolution advisory signal from the TCAS computer can be used to alter the lighting systems being activated or the rate of flashing to make the aircraft more noticeable. Alternating illuminating and obscuring of landing lights, taxi lights, deicing lights, strobe lights or rudder illumination lights enhances the conspicuousness of the aircraft to the crew of a second aircraft seeking to avoid a collision.

Claims

1. An anti-collision apparatus for an aircraft comprising:

(a) a transmitter transmitting a transponder interrogation;

(b) at least one transponder receiving said interrogation and transmitting a reply thereto;

(c) a receiver receiving said reply;

(d) a computer interpreting said reply to designate at least one said transponder as a threat; and

(e) a controller illuminating at least one external light of said aircraft in response to said designation of said threat by said computer.

2. The apparatus of claim 1 wherein said external light comprises a landing light.

3. The apparatus of claim 1 wherein said external light comprises a taxi light.

4. The apparatus of claim 1 wherein said external light comprises a deicing light.

5. The apparatus of claim 1 wherein said external light is comprises a rudder illumination light.

6. The apparatus of claim 1 wherein said external light is comprises a strobe light.

7. The apparatus of claim 1 wherein said illuminating at least one external light comprises alternate illuminating and obscuring at least one of a landing light, a taxi light, a deicing light, strobe light, and a rudder illumination light .

8. An anti-collision apparatus for an aircraft comprising:

(a) a transmitter transmitting a transponder interrogation;

(b) at least one transponder receiving said interrogation and transmitting a reply thereto;

(c) a receiver receiving said reply;

(d) a computer interpreting said reply; and

(e) a controller illuminating at least one external light on said aircraft in response to said computer'"'"'s interpretation of said reply as a threat and illuminating at least one external light on said aircraft in response said computer'"'"'s interpretation of said reply as an immediate threat.

9. The apparatus of claim 8 wherein said external light comprises at least one of a landing light, a taxi light, a deicing light, a strobe light, and a rudder illumination light.

10. The apparatus of claim 8 wherein said illumination of at least one external light by said controller in response to said interpretation of said reply by said computer comprises:

(a) alternately illuminating and obscuring a said external light at a first rate when said computer interprets said reply to be a said threat; and

(b) alternately illuminating and obscuring a said external light at a second rate when said computer interprets said reply to be a said immediate threat.

11. The apparatus of claim 8 wherein said illumination of at least one external light by said controller in response to said interpretation of said reply by said computer comprises:

(a) illumination of at least one of a landing light, a taxi light, a deicing light, and a rudder illumination light in response to said interpretation of said reply as a threat; and

(b) in response to said interpretation of said reply as a immediate threat, illumination of at least one of a landing light, a taxi light, a deicing light, and a rudder illumination light not illuminated in response to interpretation of said reply as a threat.

12. The apparatus of claim 8 wherein said illumination of at least one external light by said controller in response to said interpretation of said reply by said computer comprises:

(a) alternately illuminating and obscuring at a first rate at least one of a landing light, a taxi light, a deicing light, and a rudder illumination light in response to said interpretation of said reply as a threat; and

(b) in response to said interpretation of said reply as a immediate threat, alternately illuminating and obscuring at a second rate at least one of a landing light, a taxi light, a deicing light, and a rudder illumination light not illuminated in response to interpretation of said reply as a threat.
