During flight testing, stall in landing config is demonstrated at a steady 1kt/sec deceleration and recovery is made at either stick-shaker,scheduled stick-shaker speed minus 5 kt,or buffet,whichever comes first.Its not decelerated at idle thrust to the full stall.Nor is any airframe icing permitted.
At 110,000 lbs,stick shaker speed is within the 105-110 knots range.Vref is about 129 kts.SMYD #1 will add a TAI additive to shaker speed if WAI has been on more than 5 seconds during flight.
