I just finished my three day initial training for the 340 Cessna and it was absolutely fantastic!! The classroom was very informative and eye opening! What ever you think you know about a twin Cessna is just the tip of the iceberg compared to what you will learn. You are taught how to really handle engine failures, land safely and use the airplane again. Maintenance, troubleshooting, warning signs of problems as they are starting happen so you can avoid a serious situation.
The instructors are very, very good. They are not intimidating or condescending but teach you how to be a better, safer pilot! My instructor (Lane) really coached me and boosted my confidence level and when I left training I had no doubts that my flight skills had improved.
If you have a twin Cessna (Or any light twin for that matter) do yourself, your passengers and your airplane a huge favor by going to Aircraft Simulator Training in Burnet, Texas. It could very well SAVE YOUR LIFE!
