AMC 25.103(b) Stalling speed

AMC 25.103(b) Stalling speed ED Decision 2003/2/RM The airplane should be trimmed for hands-off flight at a speed 13 percent to 30 percent above the anticipated VSR with the engines at idle and the airplane in the configuration for which the stall speed is being determined. Then, using only the primary longitudinal control for speed reduction, a constant deceleration (entry rate) is maintained until the airplane is stalled, as defined in [CS 25.201(d)](#_DxCrossRefBm1709820668). Following the stall, engine thrust may be used as desired to expedite the recovery. The analysis to determine VCLMAX should disregard any transient or dynamic increases in recorded load factor, such as might be generated by abrupt control inputs, which do not reflect the lift capability of the aeroplane. The load factor normal to the flight path should be nominally 1.0 until VCLMAX is reached.
