This is at MTOW, CG at rear limit, from my experience, they perform almost identical to the graph:
The King AIr, "WILL" from a suitable runway, at V1, can have a power failure, accelerate to VR, and rotate gently and it will climb away on one at 12500lbs brake release weight, and will settle into a climb of circa 130 kts for around 900-1000 ft/min ROC, after raising the gear, and flap passing 400 ft agl.
It will do this, any one wish to argue the toss?? and give me all the power slide backs you want!!!!
