Abstract
A system and a method for detecting a failure of a heat exchanger provided on an engine of an aircraft. An out-of-range fuel temperature downstream of an outlet of the heat exchanger is detected. A health of a fuel tank temperature signal indicative of a temperature of at least one fuel tank of the aircraft is monitored. A main oil temperature signal indicative of a temperature of oil in the engine is received. The failure is detected based on the main oil temperature and on the health of the fuel tank temperature signal.
