Abstract: A method for detecting noncompliance with aviation regulations and operating procedures is disclosed herein. The method analyzes communication associated with a host aircraft to identify key information, stores the identified key information in a data storage device, and determines whether a particular aviation regulation or operating procedure applies to the host aircraft. After determining that a regulation or operating procedure applies, the stored key information is compared against reference information maintained in a database in association with the regulation or operating procedure. An alert is generated when the comparing detects a discrepancy between the stored key information and the reference information.
