In October 1954 TAA lost a Viscount (VH-TVA) on a training mission at Mangalore. Three pilots died. VMCA was at the core of this.
PROBABLE CAUSE: "An error of judgement on the part of the pilot-in-command in that he took the aircraft into the air at a speed below the minimum control speed....
They didn't have simulators of adequate fidelity then, but that was nearly 60 years ago. I have no idea exactly how many pilots have died in engine-out training since but it is not a small number I am sure.
The sooner this activity takes place where it can be done safely, that is in the simulator only, the better.
