Abstract: Devices, systems, and methods for providing an engine control system configured with a two-part test equipment monitor where at least one part is selectively removable are disclosed. An engine control system for an aircraft includes an electronic control unit (ECU). The ECU is configured to implement a production support equipment module and a selectively removable test support equipment module. The production support equipment module enables restricted data monitoring of the engine control system. The test support equipment module enables a comprehensive interface with the engine control system when installed with the ECU.

Abstract: Devices, systems, and methods for routing data to distributed devices in an aircraft are disclosed. A data routing system includes an aircraft and an equipment communicatively coupled to a control unit. The aircraft includes a control unit, and one or more distributed modules. The control unit is configured to communicate with each of the one or more distributed modules via an engine control bus. The control unit is configured to receive an Ethernet packet from the equipment via an Ethernet connection, translate protocols of the Ethernet packet to protocols for the engine control bus, identify an IP address in the Ethernet packet, and route data of the Ethernet packet to one of the one or more distributed modules over the engine control bus based on the IP address and the translated protocols.

Abstract: A server device that includes server elements that receive a modification request to modify a respective access permission level, designated to a client device for a target server element, from a baseline permission level among a permission hierarchy of access permission levels to a different permission level among the permission hierarchy. The server device sends a nonce associated with the modification request to the client device, and receives a signed nonce or nonce signature generated by the client device based on the nonce and a client private key of the client device. In response to determining an authenticity of the signed nonce or nonce signature based on a client public key that is associated with the client private key and trusted by the server device, the server device modifies the respective access permission level designated to the client device for the target server element to the requested permission level.
