Methods, systems, and apparatus for synthetic instrument landing system (SILS)

摘要

Methods, systems, and apparatus for Synthetic Instrument Landing System (SILS) are disclosed. By optimally integrating new SILS capabilities on existing aircraft systems and equipment, the systems, methods, and apparatus of this disclosure affect primarily one system, the MMR, and certain aircraft wiring reconfiguration and leave most of the other airplane systems as well as pilot (flight crew) training substantially unaffected. Unlike existing solutions that are based on a classical approach of new capability integration by providing associated new landing modes that are uniquely identified, the disclosure provides only a single mode to the pilot by moving all mode-specific functionality to onboard computers such as MMRs.

主权项

1. A Synthetic Instrument Landing System (SILS) device operatively coupled to an aircraft display, comprising:
means for receiving a frequency to be used for a precision approach; means for mapping a plurality of Synthetic Instrument Landing System (SILS) frequencies to Ground Based Augmentation System (GBAS) Landing System (GLS) and to Satellite Landing System (SLS) channel numbers stored in an onboard database; means for comparing the received frequency to the plurality of mapped SILS frequencies of the onboard database; means for finding a match between the received frequency and the plurality of mapped SILS frequencies of the onboard database; means for selecting an SILS approach based the matched SILS frequency of the onboard database and a current aircraft position relative to the precision approach; and means for providing ILS-like deviations on at least one cockpit display based on said selection.
