Method and system for displaying information on one or more aircraft flights, where at least one flight is determined to have at least one atypical flight phase according to specified criteria. A flight parameter trace for an atypical phase is displayed and compared graphically with a group of traces, for the corresponding flight phase and corresponding flight parameter, for flights that do not manifest atypicality in that phase.

Information display system for atypical flight phase

Method and system for analyzing aircraft data, including multiple selected flight parameters for a selected phase of a selected flight, and for determining when the selected phase of the selected flight is atypical, when compared with corresponding data for the same phase for other similar flights. A flight signature is computed using continuous-valued and discrete-valued flight parameters for the selected flight parameters and is optionally compared with a statistical distribution of other observed flight signatures, yielding atypicality scores for the same phase for other similar flights. A cluster analysis is optionally applied to the flight signatures to define an optimal collection of clusters. A level of atypicality for a selected flight is estimated, based upon an index associated with the cluster analysis.

Identification of atypical flight patterns

A fluid level monitoring systemincludes an ultrasonic interrogation deviceacoustically coupled to a sidewallof containerand produces ultrasound that travels through the liquidalong a transverse pathand an inclined path. The liquid level is determined by calculating the times-of-flight for the received return signals, where the return signal along the inclined pathreflects from the intersectionof the liquid leveland a sidewall. The devicecan be a multi-element transducer having a plurality of transducer elements at different angular orientations in a common housing.
