I recall doing a demo flite with NTSB in a CE208 reference a skydiving crash in Ga. that occurred in 85...Loaded with jumpers it stalled after TO at low alt....Eng. fail due to possible fuel contamination...At a safe alt. I was asked to set up a TO climb profile...Not loaded just two NTSB and me...First demo I pulled back to idle to sim eng. fail and not feather...Good push required to keep flying...Second demo was same except feather...Big difference and was able set up a decent glide...Another thing I recall is the 208 is a big icemaker...It requires close attention especially in trying to climb out of icing...B
