Abstract: The present disclosure provides a system that includes an ingress module arranged to receive flight data comprising a descent rate value and an altitude value; a data store comprising descent rate threshold values of at least one aircraft model, the descent rate threshold values associated, in the data store, with pressure altitude values; a descent classification module that is operably coupled to the ingress module and the data store and adapted to compare the descent rate value with the descent rate threshold values; an alert module adapted to provide, in response to the descent classification module comparing the descent rate value that exceeds at least one of the descent rate threshold values, an alert signal to a graphic user interface that is operably coupled to the alert module.

Abstract: A device includes a processor configured to obtain flight data of one or more aircraft of an aircraft type. The processor is configured to identify a first portion of the flight data as first phase flight data associated with a first phase of one or more flights of the one or more aircraft, and to apply a first aircraft performance model to the first phase flight data to determine first parameter values. The processor is configured to identify a second portion of the flight data as second phase flight data associated with a second phase of the one or more flights, and to apply the first aircraft performance model to the second phase flight data to determine second parameter values. The processor is configured to generate, based on the first parameter values and the second parameter values, a second aircraft performance model of a particular aircraft of the aircraft type.

Abstract: A device includes a memory, a network interface, and a processor. The memory is configured to store an aircraft performance model. The aircraft performance model is based on historical flight data of one or more aircraft. The aircraft performance model includes a recurrent neural network layer. The network interface is configured to receive real-time time-series flight data from a data bus of a first aircraft. The processor is configured to receive, via the network interface, the real-time time-series flight data. The processor is also configured to generate, based on the real-time time-series flight data and the aircraft performance model, one or more aircraft performance parameters. The processor is further configured to provide the aircraft performance parameters to a display device.
