A gas turbine engine and an apparatus for operating the gas turbine engine includes at least one microphone to detect the sound of impacts of particles, recorder to record the sound of the impacts, an analyser to analyse the sound of the impacts of the particles, and a store of sounds of impacts, the stored sounds of impacts correspond to unfavourable weather conditions. A comparator compares the sound of the impacts of particles with one or more sounds of impacts stored in the store 68 sounds of impacts and if the comparator determines that the sound of the impacts of particles matches one or more stored sounds of impacts, a signal is sent to a control system for the gas turbine engine to adjust the operation of the gas turbine engine such that it operates in a safe mode of operation.
A method of operating a gas turbine engine comprising detecting impacts of particles on a surface of the gas turbine engine or a surface of an associated aircraft, recording the impacts, comparing the impacts of particles with one or more stored impacts, the one or more stored impacts correspond to unfavourable weather conditions, determining if the impacts of particles matches the one or more stored impacts and sending a signal to a control system for the gas turbine engine to adjust the operation of the gas turbine engine such that it operates in a safe mode of operation.
