AMC 22.335 Design air speeds ED Decision 2003/13/RM (1) For flaps, the controls for which are intended to be operated in both high and low speed flight, the term ‘wing-flaps neutral’ in [CS 22.335(a)](#_DxCrossRefBm2056272109) and [CS 22.335(b)](#_DxCrossRefBm2056272109) is defined (unless a recognised aerofoil profile is adopted which thus defines the neutral position) as that wing-flap setting which results when one third of the total range of en-route wing-flap settings is subtracted from the most negative setting. (2) For flaps, the controls for which are intended to be operated during low speed flight only, i.e. slotted flaps, split flaps and other flaps where extension is conventional and only in the positive direction, ‘wing-flaps neutral’ is the retracted or most-upwardly-deflected setting.
