Abstract
A system, method and apparatus for monitoring the performance of a gas turbine engine. A counter value indicative of the comparison between the engine condition and the threshold condition is adjusted. The aircraft operator is warned of an impending maintenance condition based on the counter value and determines an appropriate course of action.

15. A method of monitoring the performance of an aircraft-mounted gas turbine engine, the method comprising the steps of:
-
sensing effect of at least one ambient weather condition on at least one engine operating parameter; comparing the sensed effect against a predetermined threshold condition, wherein the threshold condition is different from an engine-at-limit condition such that when the threshold condition is met continued engine operation is still permitted within a selected operational margin prior to a next related maintenance operation; warning an operator of the aircraft when the predetermined threshold condition is met; and
thenselecting at least one of a maintenance task and an operating plan for the aircraft based at least partially on expected ambient conditions at an intended destination to thereby operate the aircraft within the operational margin. - View Dependent Claims (16, 17, 18, 19)

20. A method of extending operation of an aircraft-mounted gas turbine engine, the method comprising the steps of:
-
monitoring a temperature of the engine; counting at least occurrences of a threshold temperature exceedance and occurrences of a threshold temperature non-exceedance; when a predetermined count value is achieved, selecting an aircraft flight plan to provide a cool operating environment which thereby extends permissible operation period of the engine before a next engine maintenance event is required. - View Dependent Claims (21, 22)
