The procedure is primarily targeted at high altitude/high weight where the margins between the stalls is minimum and is SOLELY disigned to keep the aircraft from stalling and provide the crew with as much time as required to try and work out what the f**ks going on and not misdiangose anything due
to any (incorrect) perception of time constraints.
I also was a non-believer initially, the day the change came out I flew at FL400, around 135,000lb, 3 degrees and 90% N1.
Was in the SIM a few days later and tried the NNC, A/P off...A/T off...F/D off...CWS set 4degrees (I'm a bad gaijin and not scared of white man magic, worked good-o)....75% N1.
SIM finally entered a shallow descent, entered the low speed margin but at no time did it approach or enter a high or low speed stall.
Suspect that's the intent Mr Boeing had in mind, if so then a success.
If you get in the SIM try it for yourself - seeing is believing - or if you really want to stir up your Flt Ops Dept try it on a line flight.
You'll most certainly attract their attention!!
