Single Engine configuration - Bell 412

Recommended Posts

I am trying to figure out single engine configuration of Bell helicopter if one engine is to shut down. The helicopter was flying in following conditions :-
Weight               -           10606 pounds
Altitude              -            7000 feet pressure altitude
Temperature      -            34 degree Celsius
Air Speed          -             70 KIAS
 
According to the OEI performance graph of 11000 weight category given in Rotorcraft Flight Manual the Bell helicopter will get a rate of descend of 370 feet per minute. 
My query is that if pilot is flying the helicopter in weight configuration, OAT and altitude given above and has to shut down one engine then what will be the 'single engine configuration'  in which pilot has to bring the helicopter before resorting to single engine ?

Probably an airspeed that is conducive to single engine operations

Exactly my thoughts, best rate of climb, and minimum rate of descent. Bell probably uses 70 KIAS as both, the charts should tell you that.

At that altitude, weight and temperature, I would use the holy Shyte Graph and hopefully you have a level surface to land on!!!!!!😱

Have fun,Don.
