Just 3 questions to the experts:
1 If there is sign of cavitation in the pumps, I presume that it involves wear on the impellers. What happens to that wear or debris; does it travel downstream or is there a filter to capture it before it enters the cans?
2 When the propeller on my boat cavitates the RPM increases but the boat goes nowhere; the prop effectively stalls. Does the same happen to the fuel pumps?
3 If temperature of fuel is an issue why hasn't anyone restricted the altitude or fuel temp of the 777 as a "safety first" prudent measure or are they looking for another incident to verify their research?
