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: Aircraft tracking and emergency location avionics architectures that integrate existing fixed Emergency Locator Transmitter (ELT) installations, their associated aircraft avionics systems and existing flight deck interfaces with an Autonomous Distress Tracker (ADT) transceiver unit in a coupled configuration. Some of the architectures allow the ADT unit and its advanced distress detecting and reporting capabilities to monitor the activation control path for the ELT and the associated ELT activation outputs. Other architectures place the ADT unit and its advanced distress detection capabilities and ground-controlled capabilities in the activation control path for the ELT. Additional architectures entail the connection of an ADT unit to an ELT remote panel on the flight deck of an aircraft.

Abstract: An aircraft avionics unit that enhances the emergency location capability of existing Emergency Locator Transmitters (ELTs). This aircraft avionics unit can be integrated with a wide range of existing ELTs and their existing aircraft interfaces by changes to a small number of the signal wires between the ELT and the aircraft systems and the addition of limited inputs from aircraft systems. This system requires no changes to either the current ELTs or the associated aircraft systems. The integrated system maintains the current ELT concept of operations while providing significantly enhanced ELT activation triggering with a low-impact, low-cost approach.
