Why is it necessary to vent all aircraft fuel tanks?

  1. To allow for fuel expansion

  2. To limit pressure differential between the tank and atmosphere

  3. To prevent fuel contamination

  4. To regulate fuel temperature

The correct answer is: To limit pressure differential between the tank and atmosphere

It is necessary to vent all aircraft fuel tanks to limit the pressure differential between the tank and the atmosphere. As fuel is used from the tank, the volume within the tank changes, which can create pressure imbalances. Proper venting allows for the equalization of pressure, ensuring safe and efficient operation of the fuel system. This answer is correct because it directly addresses the main purpose of venting aircraft fuel tanks. Options A, C, and D are incorrect: A. While fuel expansion does occur within the tank, the primary reason for venting is to address pressure differentials rather than solely for fuel expansion. C. While preventing fuel contamination is important, the primary purpose of venting fuel tanks is to regulate pressure differentials. D. While fuel temperature can affect the performance of the fuel system, venting is primarily to equalize pressure within the tank.
