Which components are typically serviced with nitrogen?

The servicing of tires with nitrogen is a common practice in aviation, including for the Super Hornet. Nitrogen is preferred over regular air for several reasons. It helps maintain consistent tire pressure because nitrogen molecules are larger than those of oxygen, making it less likely to escape through the tire walls. This leads to improved tire performance, enhanced fuel efficiency, and greater safety during flight operations. Additionally, nitrogen is less susceptible to changes in temperature and humidity, reducing the likelihood of tire pressure fluctuations during changes in altitude and environmental conditions.

In contrast, batteries, fuel tanks, and electrical systems do not typically require nitrogen for servicing. Batteries are often maintained with electrolyte levels and specific charge procedures, while fuel tanks focus more on maintaining proper fuel quality and preventing contamination. Electrical systems need to be checked for integrity and functionality without the involvement of nitrogen, making tires the clear answer in this context.
