We have often problem with Fuel Qty Indicators. The problem is often two symmetrical indicator goes Off Scale High/Low. One of the practice i saw that our maintenance personnel does is that; "They reset the CB on the ground. If the Quantity indicator comes back normal they release the aircraft for flying. Even it happened with me that I taxi back the aircraft they reset the CB while engines were running and when the indicator was alright we went for flying." I request your valuable opinion regarding the practice. Another query i have that is"How many hours can we continue flying with two symmetrical fuel quantity indicator unserviceable? What is the procedure we should follow while such flying?"
