These days, insurance companies have become savvy about the level of pilot experience that decreases the chances of an accident. They often require a minimum number of hours in a type of airplane before you can fly it solo and still be covered. But if you want to increase safety and ensure that you know the ins and outs of the airplane, meeting the minimum number of hours specified under the insurance policy is not enough. I recommend you go through a type-specific training course.
I have gone through factory training courses for several single-engine airplanes. The courses I went through spanned two to three days and covered intimate details of the systems, emergency operations, preflight procedures and avionics, to name a few. The instructors who teach these courses know these airplanes intimately and the in-depth training made me feel more confident and prepared for any potential mishaps.
