    摘要: A system and methods for generating alerts in a terrain awareness and warning system (“TAWS”) in an aircraft, using data acquired from a forward-looking radar The system comprises a forward-looking imaging device, an airport database, a navigation system, a forward-looking terrain alert (“FLTA”) processor, and a crew alerting system. The FLTA processor determines a measured clearance altitude of a highest cell within an area and compares it with a required minimum clearance altitude; if the measured altitude is equal or less than the required altitude, the crew is alerted. Alternatively, a terrain database may be used. with the FLTA processor for determining if the aircraft descends below the minimum operating altitude or is predicted to do so and then generating an alert. A method is disclosed for generating TAWS alerts using elevation angle measured by the forward-looking radar and terrain data retrieved from a terrain database.

    摘要: A terrain awareness and warning system (“TAWS”) provides input to a terrain alert (“TA”) processor from at least one real-time aircraft system or sensor and a source of terrain data; the processor determines a terrain clearance surface and a terrain airspace alert surface, and if one surface penetrates the other, the processor generates an alert signal and provides an alert signal to a crew alerting system. The two surfaces are determined by the processor by executing an algorithm(s) embedded in software containing the disclosed embodiments and methods. At least one criterion used to define an aircraft terrain alert surface is programmed to include real-time and/or static input factor data provided by at least one system or sensor input from an aircraft. Such input factor could be used to define a terrain clearance surface.

    摘要: A present novel and non-trivial system, module, and method for presenting clearance-dependent advisory information in an aircraft is disclosed. Clearances include those corresponding to interval management operations and/or trajectory management operations. Data representative of clearance information including data representative of an actual controller intervention threshold (“CIT”) information, ownship information, target information, and alert parameter(s) information is received. The actual CIT information is comprised of the CIT of a clearance assigned to an aircraft and/or an designator from which the CIT of the assigned clearance is determined. A dynamic alerting threshold is determined as a function of the received information. If the ownship position meets or exceeds the alerting threshold, an advisory data set comprised of visual advisory information, aural advisory information, and/or tactile advisory information is generated and provided a presentation system in which advisory and/or alert information is presented by an applicable unit of the presentation system.

    摘要: The present invention is a method and system for managing a transmitter located in close proximity to a sensitive receiver. In an exemplary embodiment, the method may include recognizing incomplete receive operations on frequencies that may be affected by co-site transmit operations. Further, the method may include detecting the beginning of a speech message and delaying the speech message up to a selected maximum amount of time. The speech message may be delayed to correspond to required communications performance, allowing receive and transmit operations to be coordinated and thus, reducing the possibility of the receiver to be interrupted or affected by the transmitter operating on a relatively nearby frequency.
