Abstract: A weather data aggregation and display system for displaying weather radar information to a pilot of a member aircraft of an airborne network of member aircraft. The weather data aggregation and display system includes an airborne network system (ANS) positioned on the member aircraft adapted to receive incoming geo-referenced weather data regarding Significant Meteorological Systems (SMS) from associated airborne network systems positioned on other member aircraft. A data processing system (DPS) is coupled to the airborne network system for generating the member aircraft's perspective of the SMS, based on the incoming weather data and the member aircraft's navigation and attitude information. The DPS provides DPS output weather data. An airborne display system (ADS) is positioned on the member aircraft and coupled to the data processing system.

Abstract: A terrain awareness and warning system includes electronics for receiving radar returns and providing terrain and/or obstacle alerts or warnings in response to the radar returns. The electronics receives information from a database and the information is utilized to suppress false alerts or warnings.

Abstract: Cost information is tracked for a data packet propagated through a node by receiving a data packet, creating a cost carrier descriptor and then forwarding the data packet to another node.

Abstract: A method and system for assuring separation between an aircraft and potential flight hazards is provided. According to the method, an intended path of the aircraft is predicted. A potential hazard to the aircraft along the intended path is identified. A distance from the potential hazard that the aircraft is required to maintain is determined. An ability of the aircraft to maneuver to avoid the identified hazard and to remain further from the identified hazard than the distance is determined. A probability that the aircraft will not maintain the distance from the identified hazards is determined. A pilot of the aircraft is alerted if the probability is greater than a predetermined level.

Abstract: A method of identifying errors in information describing terrain features is disclosed. According to the method, a first set of data is obtained which describes an area of terrain. The first set of data has a first type of error. A second set of data is obtained which describes the area of terrain. The second set of data has a second type of error. The second type of error is characteristically different from the first type of error. A subset of the first set of data corresponding to a first portion of the area of terrain is compared with a subset of the second set of data corresponding to the first portion to identify information not present in one of the first and second sets of data.

Abstract: An airborne network system (ANS) on a member aircraft receives incoming geo-referenced atmospheric data regarding atmospheric conditions from other member aircraft and can re-transmit the data to other members. An air data system senses local pressure and temperature conditions. A navigation system calculates geo-referenced aircraft position. An inertial data system senses member aircraft attitude, angular rates and accelerations. A data processing system (DPS) generates the member aircraft's perspective of the atmospheric conditions, based on input data from the above-mentioned systems. Network directed DPS output atmospheric data is provided to the ANS to be transmitted to other airborne network systems positioned on other member aircraft. An airborne display system is adapted to receive crew directed DPS output atmospheric data and in response thereto display desired atmospheric forecast conditions.
