摘要： A method of determining an operational state of a navigation system of a platform is provided. The method comprises testing at least a portion of hardware in the navigation system. Additionally, a measurement of at least one navigation variable from an inertial sensor is combined with a measurement of another navigation variable. A plurality of residuals for the measurement of at least one navigation variable and the measurement of another navigation variable are determined with a blending filter. An error for the measurement of at least one navigation variable is estimated based on the plurality of residuals. The method also predicts an error for the measurement of at least one navigation variable while the navigation system is in route. A determination is made as to whether the navigation system meets operational standards based on testing at least a portion of hardware, estimating an error for the measurement of at least one navigation variable, and predicting an error for the measurement of at least one navigation variable. Finally, one of a first state and a second state of the navigation system is output, the first state indicating that the navigation system does meet operational standards and the second state indicating that the navigation system does not meet operational standards.

摘要： Systems, methods and protocol for assuring separation of aircraft during parallel approaches. The systems, methods and protocol function in cooperation with existing TCAS to facilitate approaches of multiple aircraft on closely-spaced parallel runways. The systems, methods and protocol utilize data transmissions from equipped aircraft to obtain tracking information which is used in separation algorithms to generate alerts to an observer of possible threats. The systems, methods and protocol facilitate parallel approaches to closely-spaced parallel runways under Instrument Approach Procedure.
