Aircraft engine control during icing of temperature probe

摘要

Methods for controlling an aircraft turbofan engine during icing of a temperature probe and devices for carrying out such methods are described. The methods may comprise: using (46) one or more signals representative of temperature received from a heated temperature probe to generate one or more control signals for use in controlling the engine; determining (44) that an icing condition associated with the probe exists; and using (48) data representing one or more substitute signals in place of signals representative of temperature received from the heated temperature probe to generate the one or more control signals for use in controlling the engine.
