Method and a station for assisting the control of an aircraft
First Claim
1. A method for assisting the control of an aircraft participating in an exercise with other aircraft of predefined identity comprising the steps:
- broadcasting data associated with the position, the velocity and the identity of said aircraft,receiving data associated with the position, the velocity and the identity of other aircraft,processing said data broadcasted and received for determining whether there is a risk that the predicted flight trajectory of the aircraft cross any predicted flight path of a said other aircraft, and if so delivering an alert for avoiding a later collision,wherein it also comprises the steps of;
determining whether the aircraft is within a predefined first airspace volume (1) or not, said airspace volume being defined by geometrical dimensions and time of appearance and disappearance, by comparing information about said airspace volume with the position of the aircraft,making said delivering of an alert dependent upon this comparison by, when located in said airspace volume, not delivering any said alert with respect to other aircraft of said predefined identity, and when not located in said airspace volume, allowing said delivering of an alert with respect to aircraft of said predefined identity.

Abstract
A station for assisting the control of an aircraft includes warning means (5) adapted to deliver an alert for avoiding a later collision when there is a risk that the predicted flight trajectory of the aircraft crosses any predicted flight path of another aircraft. An arrangement (4) is adapted to determine whether the aircraft carrying said station is within an airspace volume with defined geometrical dimensions and time of appearance and disappearance or not and make the function of the warning means dependent upon this comparison by, when located in said airspace volume, deactivating said warning means with respect to other aircraft of a predefined identity, and when not located in said airspace volume, activate or keep the function of said warning means activated with respect to aircraft of said predefined identity.

12. A computer program directly loadable into the internal memory of a digital computer, comprising program code for assisting the control of an aircraft participating in an exercise with other aircraft of predefined identity, wherein the program code comprises sets of instructions for:
-
broadcasting data associated with the position, the velocity and the identity of said aircraft; receiving data associated with the position, the velocity and the identity of other aircraft; processing said data broadcasted and received for determining whether there is a risk that the predicted flight trajectory of the aircraft cross any predicted flight path of a said other aircraft, and if so delivering an alert for avoiding a later collision; determining whether the aircraft is within a predefined first airspace volume (1) or not, said airspace volume being defined by geometrical dimensions and time of appearance and disappearance, by comparing information about said airspace volume with the position of the aircraft; and making said delivering of an alert dependent upon this comparison by, when located in said airspace volume, not delivering any said alert with respect to other aircraft of said predefined identity, and when not located in said airspace volume, allowing said delivering of an alert with respect to aircraft of said predefined identity.

13. A computer program product in a computer readable medium having computer program code recorded thereon, wherein the program code includes sets of instructions comprising:
-
first computer instructions for broadcasting data associated with the position, the velocity and the identity of said aircraft; second computer instructions for receiving data associated with the position, the velocity and the identity of other aircraft; third computer instructions for processing said data broadcasted and received for determining whether there is a risk that the predicted flight trajectory of the aircraft cross any predicted flight path of a said other aircraft, and if so delivering an alert for avoiding a later collision; fourth computer instructions for determining whether the aircraft is within a predefined first airspace volume (1) or not, said airspace volume being defined by geometrical dimensions and time of appearance and disappearance, by comparing information about said airspace volume with the position of the aircraft; and fifth computer instructions for making said delivering of an alert dependent upon this comparison by, when located in said airspace volume, not delivering any said alert with respect to other aircraft of said predefined identity, and when not located in said airspace volume, allowing said delivering of an alert with respect to aircraft of said predefined identity.

14. A station for assisting the control of an aircraft, said station being adapted to be arranged in said aircraft (14) and comprising:
-
a transmitter (2) adapted to broadcast data associated with the position, the velocity and the identity of said aircraft, a receiver (3) adapted to receive data associated with the position, the velocity and the identity from such stations of other aircraft, processing means (4) adapted to determine, based on said data broadcasted and received, whether there is a risk that the predicted flight trajectory of the aircraft cross any predicted flight path of a said other aircraft, and if so control warning means (5) to deliver an alert for avoiding a later collision, wherein the station also comprises, means (25) adapted to receive and store information about geometrical dimensions and time of appearance and disappearance of at least one predefined first airspace volume (1) as well as a list of aircraft of a predefined identity, and an arrangement (6) adapted to determine whether the aircraft carrying said station is within said airspace volume or not, by comparing the information about said airspace volume with the position of the aircraft, and make the function of said warning means (5) dependent upon this comparison by, when located in said airspace volume, deactivating said warning means with respect to other aircraft of said predefined identity, and when not located in said airspace volume, activate or keep the function of said warning means activated with respect to aircraft of said predefined identity. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
