Indicating system for warning airspace or threatening aircraft in aircraft collision avoidance system
First Claim
1. A warning airspace indicating system belonging to an aircraft collision avoidance system of a subject aircraft having a function of determining the existence of danger of aircraft collision by receiving response signals from other aircraft in response to interrogation signals delivered from said subject aircraft, said indicating system for warning airspace or threatening aircraft in said aircraft collision avoidance system including a means for defining a warning airspace arranged around said subject aircraft, wherein the range of the warning airspace expands and contracts along the flight direction of said subject aircraft in dependence upon the speed of said subject aircraft, said warning airspace defined to have a shape including a cylindrical shape of fixed diameter centered on said subject aircraft and another cylindrical shape of variable diameter which varies in accordance with the speed of the subject aircraft and whose center is disposed along the flight direction of said subject aircraft at a distance from said subject aircraft which varies in dependence upon the speed of said subject aircraft.

Abstract
The present invention relates to a indicating system for warning airspace or threatening aircraft in aircraft collision avoidance system which provides simply and inexpensively information required for safe cruising of aircraft with respect to range of warning airspace of aircraft, positions of other aircraft involving threatening of collision, and flight courses of proximate said other aircraft involving threatening of collision.
The present system can provide simply and inexpensively information indispensable for safe cruising of aircraft with respect to range of warning airspace of aircraft, positions of other aircraft involving threatening of collision, and flight courses of proximate said other aircraft involving threatening of collision by such manner that the warning airspace is changed into a required shape in response to speed of a subject aircraft, and indication range for the threatening aircraft is changed in response to angle of climb or descent of the subject aircraft, besides detected data of distances and bearings with respect to the other aircraft are indicated by a prescribed afterglow time.
