One Asian airline introduced a call by the PM of "Stable" when the N1's were stable at 40% N1. This was not a Boeing SOP call but someone in management who thought it was a good idea at the time. On this occasion the PM was quietly advised by the simulator instructor on the private intercom, not to call "Stable."
The captain released the brakes and pushed the thrust levers to the 40% N1 position in preparation for hitting the TOGA button. T he 737 trundled down the runway at 40% N1 slowly gathering speed while the captain waited for the PM to call "Stable" which never occurred.
Passing the 1000 feet runway marker still at 40% N1, the captain looked accusingly across the cockpit to the PM and said "You forgot to call Stable."
This proved without any doubt some pilots rely 100% on an SOP call to initiate an action rather than using common sense.
