DC-3 Single Engine Performance
It's getting late here. I'll post more tomorrow after I learn more.
I've got about 3,000 hrs. PIC in DC-3s. Single engine performance depends on how good the pilot is, how strong the remaining engine is, and weight of the aircraft.
The book says it should climb out at better than 300 fpm on a single engine at gross. I don't know which model 3 this is, so gross could be anything between 25,200lbs. to 26,900lbs.
From the overview I looked at, I think the pilot didn't use enough right rudder to keep her straight. She drifted left, and I couldn't tell from the photos if the left prop was feathered. If it wasn't, she wouldn't climb.
