How Do They Do It? Jumbo Jet Tire Change
If you've always wanted to learn how mechanics change jumbo jet tires, then check out this interesting "How do they do it?" segment. Video after the break.
Aircraft tires are usually inflated with nitrogen in order to minimize expansion and contraction from extreme changes in temperature experienced during flight. Dry nitrogen expands at the same rate as other dry atmospheric gases, but common compressed air sources may contain moisture, which increases the expansion rate with temperature
