A warning method for an aircraft includes receiving a first parameter indicative of an aircraft's flight path, calculating a stable approach value based on the first parameter, receiving a second parameter indicative of the aircraft's turbulence, calculating a turbulence factor based on the second parameter, calculating a safe landing value based on the stable approach value and the turbulence factor, comparing the safe landing value to a threshold value, and providing an aircraft warning when the safe landing value fails to meet the threshold value.

Fabrics are treated with a hydrophobic treatment that includes at least one hydrophobic monomer and a crosslinker. The treatment is low in volatile organic compounds and water. It is a liquid at 22 C. or a suspension having a phase that is liquid at 22 C. The monomer and crosslinker are cured in a free radical polymerization to form a hydrophobic coating on a fibrous substrate.

Systems and methods for UAV safety are provided. An authentication system may be used to confirm UAV and/or user identity and provide secured communications between users and UAVs. The UAVs may operate in accordance with a set of flight regulations. The set of flight regulations may be associated with a geo-fencing device in the vicinity of the UAV.

A method and system for downloading aeronautical data using an automatic dependent surveillance-broadcast (ADS-B) is provided. The method comprises creating a first data sequence structure that includes a receive time for each of one or more received ADS-B messages; creating a second data sequence structure that includes a packet time for each of one or more received aeronautical data packets that are without position information; mapping the received aeronautical data packets respectively to the ADS-B messages by comparing the receive time for each of the received ADS-B messages with the packet time for each of the received aeronautical data packets to produce a correlation between the ADS-B messages and the aeronautical data packets; and deriving position information for each of the received aeronautical data packets from each correlation between an ADS-B message and an aeronautical data packet.

A computer-implemented method of communicating with an unmanned aerial vehicle includes transmitting a first message via a communications transmitter of a lighting assembly for receipt by an unmanned aerial vehicle. The first message includes an identifier associated with the lighting assembly, and the lighting assembly is located within a proximity of a roadway. The method also includes receiving a second message from the unmanned aerial vehicle via a communications receiver of the lighting assembly. The second message includes an identifier associated with the unmanned aerial vehicle. The method further includes transmitting a third message via the communications transmitter of the lighting assembly for receipt by the unmanned aerial vehicle. The third message includes an indication of an altitude at which the unmanned aerial vehicle should fly.

A common operating environment (COE) display system for vehicle operations, such as for air transport provides coordination of logistics information with dispatch or a controller. An operational plan, such as a flight plan or other operational plan describing vehicle deployment is stored, and a map visualization system displays a map region. An in-vehicle display depicts the operational plan, providing displays of current and projected operational conditions of the vehicle within different time phases of the operational plan. Communication as either text or other data allows transmission can be performed as text, attachments or a combination of text and attachments. Messages (text) and attachments (files) are exchanged only through the server, and the items exchanged are recorded for analysis and forensic purposes.

An associative memory system, method and computer-readable storage medium are provided to modify a flight plan. In regards to an associative memory system, a receiver module is provided that is configured to receive a flight plan of an aircraft. The flight plan includes a plurality of attribute categories and their associated attribute values. The associative memory system also includes an associative memory configured to compare attribute values of the flight plan with corresponding attribute values of prior flight plans to identify one or more related flight plans. The one or more related flight plans include intangible data related to a respective flight. The associative memory system also includes a modification module configured to modify the flight plan of the aircraft based upon information from one or more of the related flight plans, including the intangible data from one or more of the related flight plans.

A system and method for management of airspace for unmanned aircraft is disclosed. The system and method comprises administration of the airspace including designation of flyways and zones with reference to features in the region. The system and method comprises administration of aircraft including registration of aircraft and mission. A monitoring system tracks conditions and aircraft traffic in the airspace. Aircraft may be configured to transact with the management system including to obtain rights/priority by license and to operate in the airspace under direction of the system. The system and aircraft may be configured for dynamic transactions (e.g. licensing/routing). The system will set rates for licenses and use/access to the airspace and aircraft will be billed/pay for use/access of the airspace at rates using data from data sources.

Systems and methods for updating a terrain awareness and warning system (TAWS) database are disclosed. The systems request, by way of the first wireless communications device communicating by way of an avionics data transfer protocol, an update to the TAWS database, where the request is based upon flight path data, and receive and accept, by way of the first wireless communications device and by way of the avionics data transfer protocol and in response to the request, the update to the TAWS database.

A method for evaluating an output pattern printed on a medium is described. A reference pattern is stored. The output pattern is printed on the medium based correspondingly on the stored reference pattern. A scan based instance of the output pattern is rendered, which has a set of features at least corresponding to the printed output pattern and zero or more features additional thereto. A difference image, having the zero or more features of the rendered scan instance, is computed based on a comparison of the rendered scan instance to the stored reference pattern. Upon the zero or more features including at least one feature, the computed difference image is evaluated in relation to a proximity of at least one feature to locations pixels of the reference pattern.
