First of all and foremost; a DC-3 simulator is a great tool to make training for DC-3 pilots safer, more realistic and thus will prepare pilots better for real equipment failures. Certain maneuvers are too dangerous to perform on a real DC-3. These maneuvers put the airplane, the pilots or both in jeopardy. These maneuvers may even be prohibited by government entities like the FAA or the EASA and involve simulated engine failures below 500 ft or rejected take-off training. A propeller runaway in which the propeller revolutions per minute exceed the normal range cannot even be practiced at all! Better trained pilots are better prepared when things really go wrong. They will have the skill set and knowhow to resolve the situation at hand.
Secondly; training on the real deal is hard on the most important pieces of equipment; the engines. Simulated engine failures can only be accomplished by closing the throttle on one of the engines. If this procedure is not accomplished correctly or mishandled it could shock cool the engine in question since these big lumps of steel are to be heated and cooled gradually to prevent damage. On the “simulated” good engine the power output needs to be increased which makes the engine hotter than normal.
The third reason why having a DC-3 simulator is a great asset, is all about costs. Since a real DC-3 is expensive to operate, training the pilots that way is an expensive activity. You would want to train pilots until they are proficient but extra training costs would not be desirable. In a DC-3 simulator you can train pilots until they see blue in the face and then some by a fraction of the costs. More training for better pilots!
