Abstract
A method of monitoring the health of a gas turbine engine of at least a pair of engines of an aircraft for example. The method comprising the steps of: a) obtaining steady state readings from predetermined sensors on the engines; b) calculate a percentage difference of the steady state readings from a unique engine linear synthesis model for each engine; c) compare the difference between the percentage differences for each engine and d) where this difference exceeds a predetermined value issue a warning as to an engine health problem. Maintenance of the engine can therefore be advantageously scheduled.

A method of monitoring the health of a gas turbine engine of at least a pair of associated engines, the method comprising the steps of
- obtaining steady state readings from predetermined sensors on the engines, calculate a percentage difference of the steady state readings from a unique engine linear synthesis model for each engine,
- compare the difference between the percentage differences for each engine and where this difference exceeds a predetermined value issue a warning as to an engine health problem.
