Neg, the boeing has hydraulic accumulators (limited batteries for hydraulics) for flight controls. Also electricly operated backup elements.
Control wouldnt have been an issue. Not at engine spool down.
By the time the RAT had spun up they would of had electrics and the apu was already on its way to cycling on.
Essentially everything would have been working other than thrust.
Now as airspeed decayed and they essentially flat stalled on to the deck they would have lost aerodynamic authority due lack of airflow over control surfaces… but in those first few seconds… if they had pitched down to glide to maintain mim soeed and not decay energy as fast, as counter intuitive as it is they would have lost overall height slower.
But its symantics really.
Im sure someone somewhere is gaming this in the sim.
Minimum drag speed, clean, maybe better odds. With gear / slats / flaps out, very little option to stretch things.
After all the mandatory ticks had been done in the sim (A300-B4, Falcon 2000EX Easy), we used to do double engine flame-outs (from altitude) & see what worked out best. Clean configuration obviously gave more game time, everything out was a brick going earthwards very quickly with a massive rate of descent.
