  • Patent number: 12515814
    Abstract: Methods and systems for testing an aircraft in-flight are described herein. The method can include receiving a test deck including one or more test cards, with an individual test card including an ordered list of points. For an individual test card, points of the ordered list of points can be performed, a status for the performed points of the ordered list of points can be assigned, a current fuel value for the aircraft can be received, and the current fuel value can be compared to an expected amount of fuel required to perform the remaining test cards. In response to the comparison indicating that the current fuel value is not sufficient for the remaining test cards, the method can include modifying the test deck at least until the current fuel value is sufficient for executing a subset of remaining test cards.

  • Publication number: 20250276811
    Abstract: Systems, methods and computer-readable media for telemetry data visualization are described herein. The described system includes paths and reduced components in between reception of sensor data and display to an engineer, reducing time delays and reducing the possibilities of scenarios where telemetry does not reach the responsible engineer to monitor and respond to various situations that may arise. In particular embodiments, a communications hub allows telemetry sensor readings to be simultaneously consumed by multiple components in memory-optimized fashion.

  • Publication number: 20190385100
    Abstract: A system for modeling an entity includes a prediction module configured to identify one of a plurality of entities using a set of criteria filters to construct a model for the entity with model features built from data about the entity. The prediction module computes a diffusion model coefficient ? based on a diffusion parameter vector ?, and a drift model coefficient ? based on a drift parameter vector ?. The module computes a predicted entity success probability and a success interval confidence interval. A portfolio selection module is configured to receive a score measuring success for the plurality of entities based on the model, order the scores in a rank order, and form a portfolio from top n scoring entities. A prediction interpretation module receives parameter vectors ? and ? and entity model coefficients ? and ? and uses distributions of ? and ? to correlate entity features with success prediction.
