I found a great explanation of Turbocharged engines. (Not Turbo props or jets).http://www.lycoming.textron.com/main.jsp?b...bocharging.htmlBut I have a Q:In a Turbochared aircraft like a Seneca II or a Skylane, can I turn off the Turbo component and fly it like a normally aspirated engine on the fly (no pn intended); something like, turn of the Turbo switch or something.. Manny

Manny The answer is No sorry.

Heck, not only can you not turn it off in flight, you couldn't talk a A&P mechanic into turning it off when he's working on it on the ground. Have you ever had a look under the hood of a T206 or T210. I don't blame them. Not to mention all the paperwork (337s and STCs) involved.

Manny,I have to ask, why would you want to?

AY,I think, you figured it out from the other thread.Cause.. I want a Seneca I (Non turbo) fsim aircraft. :)
