Abstract: A power management control system provides control and graphical representation of a plurality of electrical devices and components of an electrical distribution system. The control system includes a virtual three-dimensional annunciator panel for displaying an indication of the status or condition of a plurality a plurality of electrical devices of an electrical distribution system. The virtual annunciator panel includes an array (6×8) of indicator buttons that represent a particular device, event or group of events of the PMCS. The buttons are displayed in different colors to indicate different alarm systems. The annunciator panel functions to notify the user/operator of an alarm condition of a device, as well as permits the user to acknowledge alarms. The development of the virtual annunciator panel display is automated using software, namely an Annunciator Panel Wizard.

Abstract: A method of, and a system for, detecting an occurrence of a surge in a gas turbine engine. The method includes steps, executed during consecutively occurring time periods, of: obtaining filtered derivatives of first and second engine operating characteristics; comparing the filtered derivatives of the first and the second engine operating characteristics to first and second threshold values, respectively; and incrementing a count only if both of the filtered derivatives exceed their respective threshold values. Otherwise, a next step decrements the count if one or both of the filtered derivatives do not exceed their respective threshold values. The method further includes a step of indicating a surge condition only if the count is equal to a predetermined value that is greater than unity. In a presently preferred embodiment of this invention the engine is a turbofan engine, the first engine operating characteristic is fan speed, and the second engine operating characteristic is exhaust gas temperature.
