Abstract: An avionics unit assembly for an aircraft can include an avionics unit (e.g., an underwater locator device, “ULD”), and a battery to power the avionics unit. The avionics unit assembly can further include a housing that encases the avionics unit and the battery. The housing includes a vent port for exhausting an emission from the housing during a failure of the avionics unit. The avionics unit assembly can further include one or more of a suppressor that filters the emission, a shield element that is resistant to chemical and/or thermal effects of the emission, and a bracket for mounting the avionics unit to a surface. A method integrating the avionics unit assembly onto a forward aircraft bulkhead at a mount location under an aircraft radome and for manufacturing the avionics unit, and an aircraft including the avionics unit are also described.

Abstract: A method and system integrates the monitoring of system components and detecting errors or potential problems (or both) in components of bulk fuel distribution facilities. Generally, the method and system includes a diagnostic support module for identifying what stand alone software modules, what fuel hardware, and what software interfaces/drivers associated with the fuel hardware are present in a bulk fuel distribution facility. After the diagnostic support module identifies the unique system components of a particular bulk fuel facility that can include software and fuel hardware, the diagnostic support module can perform system checks of the system components to determine if any system components are missing or if errors or potential problems (or any combination thereof) may exist in a particular bulk fuel distribution facility. The system checks performed by the diagnostic support module can include comparing information collected from the system components against a predetermined set of validation rules.
