True or False: Sealing is used in airplane assembly to help contain fuel, maintain pressure and prevent corrosion.

Sealing is an essential process in airplane assembly for several vital reasons. It helps contain fuels and fluids within the aircraft systems, ensuring that there are no leaks that could compromise safety or performance. Additionally, sealing plays a significant role in maintaining pressure within various chambers and systems, which is crucial for the operational efficiency of aircraft. Furthermore, seals are also instrumental in preventing corrosion by providing a barrier against moisture and other contaminants that might affect the integrity of materials used in the aircraft structure.

Sealing methods and materials are specially designed to withstand the unique conditions encountered in aviation, including extreme temperatures, pressures, and exposure to various chemicals. Given these critical functions, it is true that sealing is utilized in airplane assembly for these purposes, making the answer to the question accurate.
