Till You get Vmc(a) you have 2 times the chance of losing directional control due engine power loss. It's a reduce power on the other side quickly.. The RAAF sometimes took off on short fields based on stall speed only but it's far from a standard operation. AT Vmc(a) you need FULL rudder to stop Yaw.. Not easy to pull a wing off a DC3 unless you hit the ground with it. They made well over 10,000 of them.. Nev
