Abstract: A multi-engine aircraft includes a first engine drivingly engaged to a common rotatable load and a second engine drivingly engaged to the common rotatable load, the second engine having a bleed air system and a control system in communication with a compressed air switching system. The control system controls operation of the second engine and/or the compressed air switching system. The compressed air switching system includes a switching valve that is displaceable between at least a first position and a second position, the first position interconnecting a lower pressure inlet and a switch outlet, and the second position interconnecting a high pressure inlet and the switch outlet. The switch outlet is in communication with the bleed air system of the second engine. The control system actuates the switching valve to switch between the first and second positions.

Abstract: Systems, methods, and non-transitory computer readable media are provided for determining routes within a location. Location information for a location may be obtained. The location information may include terrain information for the location. A set of restricted regions within the location may be determined based on the location information. A set of paths within the location may be determined based on the set of restricted regions. An interface through which information describing the set of paths within the location is accessible may be provided.

Abstract: A method of operating a multi-engine aircraft having two or more gas turbine engines includes operating a first engine in a powered mode to provide motive power to the aircraft, and, in flight, operating a second engine in either a powered mode to provide motive power to the aircraft or in a standby mode to provide substantially no motive power to the aircraft. When operating the second engine in the powered mode, pressurized air is bled from a first bleed location of a compressor of the second engine. When operating the second engine in the standby mode, pressurized air is bled from a second bleed location of the compressor of the second engine and supplying the pressurized air to a bleed air system of the second engine. The second bleed location is downstream of the first bleed location within the compressor of the second engine.

Abstract: A system with an interactive user interface for a plurality of users to author an electronic document simultaneously is described. The system displays visual feedback on the interface to prevent the users from interfering with one another. The system displays data from a remote database linked into the document based on unique identifiers. The data is displayed as an “artifact.” The system monitors and tracks each user's access category level, as well as the access category level of each piece of data pulled from the remote database. The system compares a user's category level to the data from the database to make visible only the portions of the document the user has the appropriate access category level to view and/or modify. The portions of the document that have a higher category level than the user will be hidden from the user either in part or completely. Also, there may be an indicator to the user of such redacted or hidden content from the user's viewer.

Abstract: A system and a method are provided for collaborative data entry and integration. An operation performed by the system and the method include causing a collaborative interface for input to a spreadsheet to be provided via a user interface, receiving a data entry to the spreadsheet via the collaborative interface, validating the received data entry based on one or more validity rules associated with the spreadsheet, capturing a snapshot of the spreadsheet including the validated data entry, and causing at least the validated data entry of the spreadsheet to be integrated into datasets for one or more applications, at least based on the captured snapshot of the spreadsheet.

Abstract: An example method of enforcing granular access policy for embedded artifacts comprises: detecting an association of an embedded artifact with a resource container; associating the embedded artifact with at least a subset of an access control policy associated with the resource container; and responsive to receiving an access request to access the embedded artifact, applying the access control policy associated with the resource container for determining whether the access request is grantable.

Abstract: A method of operating an engine of an aircraft, the engine having a bleed air system. The method includes in flight, directing pressurized air from a source of pressurized air external to the engine to the bleed air system of the engine. An aircraft, comprising a first engine having a bleed air system, a second engine having a bleed air system, and a source of pressurized air that is external to the first and/or the second engine, the source of pressurized air being selectively fluidly connectable to the bleed air system of the first and/or the second engine, is also disclosed.
