Question

<p>If you've ever flown, or been flown in, a twin-engine propeller-driven airplane, you know all about the irritating waaah-waaah-waaah sound that's heard whenever one engine is turning slightly faster than the other. It's so irritating that most high-end twins have a button labeled "auto-synch" - the pilot presses it, and engine speeds are automatically matched, exactly. Explain, in as much technically accurate details as you can, exactly where this irritating sound comes from. Feel free to include accounts of your personal experiences, or similar experiences that are due to the same phenomenon.</p>

Explanation / Answer

here a good example.......given below... The Mitsubishi MU-2 has a very bad accident record, and now the experience requirements for pilots are so high, and insurance coverage so expensive that it would be a very impractical choice. Those still in use have pretty much gone over to freight because of the liability issues. I have not flown Mu-2's but have researched them extensively for the company I now fly for. They decided against buying one. The Piper Chyenne is another older twin turboprop that you might find in the $500k range but it will probably have high time engines and older avionics, paint and interior. Worth a look, but I don't know much about them.
