Therefore the order in which a sled may bump up into the next higher class goes as listed by displacement. No smaller displacement FA or LC may bump into a larger displacement fan class. Respectively, no smaller displacement L/C may bump into a larger displacement FA class.

An accurate bump schedule is incorporated within the class listing.
