In one form, the asymmetric luggage stowage bin arrangement is used as a retrofit to replace shelf-style luggage stowage compartments common to older style aircraft. The instructions specify what changes to make to a generic input file. The idle speed error is representative of the difference between an idle speed set point and the measured rotational speed, n.
