| Yep particles on filters are important cos...
helicopters use an early waning system similar. Eg Bell Jet Rangers have a device in the turbine which is connected to the engine chip (chip as in chips of metal not electronic or potato...) lamp on the instrument panel. If more than a very few small particles end up on this sensor the lamp light up and you gotta put down and check it out. It is definately a sign of impending engine failure, bike or chopper! |
