In my initial post I was purposely vague as to the nature of our operation in order to generate unbiased discussion. We are, in fact, military making the transistion to a new machine with more civilian-like ways in line with OEM direction. However, the SOPs remain ours to direct (to some extent). So...

"Later calls are problematic as they signify nothing unless they are set to Vstayup or some other positive point."
Aye, there's the rub. My real question then is: what value is there in calling any speeds between 'Airspeed's alive' and Vy?
Each will aid the PF's SA, but what value do they provide?:
Safe-Single or Stay-up based on 30s OEI: only assures level flight for the next 30 sec, but allows the PF to know he's in the regime where he can choose to flyout using contingency power to achieve Vtoss or Vy;
Stay-up or SSES based on Max Continuous power: sustained level flight with contingency power available to climb or accel to Vtoss or Vy;
Vtoss: 100 fpm climb is assured and a better angle of climb; or
Vy: flying and climbing.
The OEM Stay-Up charts are based on OEI max continous, and some believe OEI 30s is more realistic to use.
Thoughts?
