What can be done to eliminate or minimize the microbial growth problem in an aircraft jet fuel tank?
Use desiccants
Increase fuel temperature
Use anti icing and antibacterial additives
Seal the tank completely
The correct answer is: Use anti icing and antibacterial additives
Using desiccants or increasing fuel temperature would not eliminate microbial growth in the fuel tank. Desiccants only absorb moisture and do not directly address microbes, while increasing fuel temperature can actually accelerate microbial growth. Sealing the tank completely may not be possible as the tank needs to be open for refueling. The most effective solution is to use anti-icing and anti-bacterial additives specifically designed to combat microbial growth in fuel tanks. These additives can prevent and minimize microbial growth, ensuring safe and efficient operation of the aircraft.
