Question 167Gas Turbine - Assistant Engineer

The correct answer is D) Lube and scavenge pump. The lube and scavenge pump is responsible for removing oil from the transfer gearbox and circulating it through the lubrication system. This pump draws oil from the gearbox, passes it through filters and coolers, and then returns the cleaned and conditioned oil back to the gearbox to provide lubrication. The other options are incorrect because: A) the lube oil storage and conditioning assembly does not directly remove oil from the gearbox, B) the air-oil separator removes air from the oil but does not directly remove oil from the gearbox, and C) the duplex filter assembly filters the oil but does not actively remove it from the gearbox.
