A neural network trained via machine learning and running on the FQPU receives fuel quantity (FQ) inputs from fuel tank sensors, e.g., tank density, fuel volume, water presence within the tank, at or near a given measurement time. The neural network additionally receives fuel flow (FF) inputs from flow sensors at the measurement time, indicating fuel flow to engines and auxiliary power units (APU) of the vehicle. Based on the FQ inputs and the FF inputs, the neural network calculates an estimated fuel quantity (EFQ) remaining, e.g., across all fuel tanks at or near a particular measurement time.

A GNSS active antenna with improved performance in the presence of interfering signals is described. The GNSS active antenna meets the requirements of DO-301 for Airborne GNSS antennas when in normal operation. The GNSS active antenna also generates a low elevation null steered to any azimuth angle when in an environment with an interfering signal. The null has minimal performance impacts at higher elevation angles near zenith. The GNSS active antenna includes a right-hand circular polarized microstrip antenna with a concentric vertically polarized monopole antenna. The GNSS active antenna also meets the requirements of ARINC 743 antenna outline and mounting hole pattern.

Aerial image geo-registration via aeronautical database content as ground control points
A system and method for creating avionic databases is disclosed. The system may receive an avionic database of an area, surveyed coordinate points of the area, and new satellite imagery of the area. The system may georeference the new satellite imagery using the surveyed coordinate points as ground control points, generating georeferenced coordinate points of the new satellite imagery in different locations of the area. The system may create a second avionic database based on the georeferenced coordinate points.
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.
