Uses

This alternative parameterization of the Normal distribution is useful for modeling expert estimates of some continuous quantity with equal tails, like time or cost to complete a task.

The NormalAlt distribution appears in the standard Select Distribution palette. It also appears in the Expert selector window when one selects two percentiles {(P1, X1), (P2, X2)}.
