Claim One:
1. A system for trend monitoring in an aircraft, the system comprising: a memory device; a display device; and a processor coupled to the memory device, a source of critical parameters, and the display device, the processor configured to: initialize, for a critical parameter, a first threshold (t1), and a first alert table (a1), wherein a1 comprises, for t1, a list of probable causes associated with exceedance of t1, a respective list of corrective actions, and a communication protocol for the display device; receive, at a first time, for the critical parameter, a valid first actual data, and a valid first predicted data; determine a first current deviation defined as a difference between the first valid actual data and the first valid predicted data; assert a flag upon determining that first current deviation exceeds t1; determine a content and format for an alert based on the asserted flag and the critical parameter; identify a probable cause and corrective action associated with the alert in response to referencing a1; and command the display device to render the alert, probable cause, and the corrective action, in accordance with a1.
