Abstract: Whenever an avionics computer system receives a flight plan, the avionics computer system performs rules-based conformity checks with respect to a predefine set of rules/thresholds. The rules may be general aviation best practices (no rate of elevation change beyond some threshold, no single change in direction beyond some threshold, etc.) or specific to the aircraft (no violation of an operational ceiling, no violation of some defined fuel reserve, etc.). Violations of the rules and criteria are communicated to crew members via visual indicia of such violations, including the relative severity.

Abstract: An aircraft-based system for tracking and verifying control inputs from potentially incapacitated pilot stores to memory expected control input sets, e.g., control procedures for controlling an aircraft through segments of a flight plan. When pilot monitors indicate a state of potential incapacitation of a pilot (e.g., fatigue, unresponsiveness, hypoxia), the control input tracking system records any control inputs submitted via the flight deck controls by the incapacitated pilot, reviewing each recorded control input compared to expected control inputs (e.g., for the current flight segment). When a recorded control input sufficiently deviates from the corresponding expected control input (e.g., such that aircraft safety or mission criticality may be affected), the pilot and/or flight crew may receive feedback alerting to the deviant control input (e.g., which may be overridden or which may require confirmation prior to execution).

Abstract: A system and method are provided for selecting features from a digital chart, and entering corresponding flight plan amendments into a flight plan by direct transfer to an FMS. Based on the selection, the system may prompt the user for subsequent selections. Digital charts are generated in dynamically or in real-time according to a set of databases, including the databased used by the FMS. Elements within the databases are characterized so that the flight crew can select which elements are displayed. Features in the digital chart may be made selectable or unselectable based on a filtering process. The filtering process may be based on environmental variables, aircraft capabilities, safety tolerances, etc.

Abstract: The US DoD is moving to incorporate 5G, particularly for sidelinks networks. 5G sidelink network are desired to operate at company, platoon, and squad levels independent of connection to 5G base stations (gNB). The 5G sidelink standards, as defined by 3GPP, cannot operate under active jamming at expected threat levels. The sidelink standards are defined for commercial use and cannot withstand active jamming. Various prior art uses beamforming, directionally beamformed MIMO, and even distributed MIMO as potential options to address active jamming. The SWAP-C and standards of the 5G UEs are not conducive to these anti-jamming techniques. A solution is described that uses the 5G sidelink physical layer with modifications at the control layer to avoid denial of the S-SSB. Intra-, inter-squad, and squad-to-command post communications may use the solution to avoid denial of the 5G sidelink.

Abstract: A system and method for offloading Future Air Navigation System (FANS) and Automated Dependent Surveillance-Contract (ADS-C) functionality from the flight management system (FMS) to an aircraft-based communications management unit (CMU) receives intent data outputs from the FMS, each intent data output including aircraft state and trajectory intent data. Based on the received intent data outputs, the CMU generates a dynamic route representation approximating the aircraft route, inferring and connecting waypoints without otherwise querying the FMS or the pilot for additional data. The CMU receives inbound messages related to ADS-C contracts established with the aircraft by air traffic control (ATC) ground stations and, based on the dynamic route, generates and transmits any necessary ADS-C reports to the ATC ground stations. Further, the CMU queries aircraft-based absolute and relative navigational systems to verify navigational system availability and accuracy status with each ADS-C report.

The combined normal mode radiating element and and-fire mode radiating element attenuators or variable gain amplifiers for amplitude adjustment, phase shifting, and time delay circuitry and algorithms to drive the normal mode radiating element and end-fire mode radiating element simultaneously to produce radiation patterns that constructively interfere. Alternatively, the radiating elements are fed by a radio frequency (RF) feed and switching integrated circuitry timed to drive the normal mode radiating element and end-fire mode radiating element to effectively produce hemispherical radiation patterns as a function or time/scan angle.

Abstract: A radar system including an AESA illuminates a target with a first pulse for a desired beam pointing angle (azimuth and elevation). The AESA then illuminates the target with a second pulse for the desired pointing angle, the second pulse defining a radiation pattern with a main beam in phase with the first pulse, but side lobes that are out of phase. The radar system receives return signals and combines the return signals to null the side lobes by the principle of superposition. The radar processing unit is time synced such that the pulse-pair is interpreted as a single ultra-low level side lobe return radiation pattern.

The gadolinium layers are designed to shield semiconductor chips from neutrons. Shielding the semiconductor chips from the neutrons reduces the upset rate of device packages using the semiconductor ships.
