A remote sensor interface is co-located with the plurality of remote sensors. The remote sensor interface includes a communication bus having a plurality of nodes to transmit data from the plurality of remote sensors. A plurality of subsystems are each adapted to receive data from the plurality of remote sensors simultaneously and in real time via the remote sensor interface. A remote sensor data acquisition method for an aircraft includes sensing one or more parameters onboard the aircraft via a plurality of remote sensors and transmitting sensor data from the plurality of remote sensors to a plurality of subsystems independently and in real time via a remote sensor interface.

A method for installing a replacement electrical heat sensor in a heatable aircraft window laminate structure comprising the steps of: drilling a blind hole in the edge of the window laminate; routing a channel in the edge of the window laminate from the blind hole to a terminal block of an originally installed heat sensor; inserting the replacement heat sensor into the hole; filling the hole with a material to seal the hole and the heat sensor from contamination; heating the window laminate; photographing the window laminate using an infrared camera to determine uniformity of heat distribution; placing a heated plate against the exterior surface of the window laminate directly over the position of the replacement heat sensor; measuring an electrical resistance of the replacement heat sensor to confirm proper operation of the replacement heat sensor.

A method is provided for reconfiguring a vehicle for transfer from a first operator to a second operator. The method includes accessing first datasets that define an initial configuration of the vehicle, importing second datasets that describe maintenance, repair or service of the vehicle during in-service operation with the first operator, and generating a first composite dataset defining a current configuration of the vehicle. The method also includes accessing third datasets that define requirements of the vehicle for in-service operation with the second operator, and generating a second composite dataset that defines a target configuration of the vehicle from the first composite dataset and based on data of the third datasets. The method includes comparing the first and second composite datasets to identify modifications to reconfigure the vehicle from the current configuration to the target configuration, and generating a visual presentation of the modifications to facilitate reconfiguration of the vehicle.
