multi-engine aerodynamics

[PILOTO]

hello! i need some help understanding multi aerodynamics. what are the factors affecting Vmc? why the left engine is the critical engine? does anybody know a good site that i can go and look? thank you very much.

How about reading your book. You DO have a book, right?

Yeah, I've got to agree with Dumble on that one.

See, when the left engine, on a conventional Multi-Engine airplane stops, it is not directing it's propblast at the tail, and the right engine is not directing it's propblast at the tail, and you roll upside down and die.

However, if you fly a plane with two tails, (see avatar), you don't have that problem, you just feather the engine that failed, declare an inconvenience, and keep on going.

Oh, there's a story, the superskyrocket.com folks told me about one of their european customers, who was on his way home after taking delivery of one of their modified airplanes. He called from Goose Bay, and said, listen, can I fly on one engine. The superskrocket folks said, oh no, get it fixed right away. A few months later, they were following up, how do you like your plane, and he said, I really got to get that engine fixed, it flies slow on one engine.

Does that explain it all??

Oh, it's all pretty simple. uke:
Instead of the book. Okay, get the book, but for simple understanding, get the King School video on ME, and John can explain it really well.

Normally I don't go for that kind of answer but there literally are chapters that cover the topic and I think someone would exceed the forum limit to attempt it here. There is a LOT of information on it.

I have to agree, there's too much to get into....get the book

piloto - what has your instructor told you to do? PM me with your email and I will see what I can do in explaining things or I can call you, but they are right it is a pretty big subhect.

On the other hand I would be happy to discuss it so you gain a further understandiing of Vmc and multiengine aerodynamics

If that doesn't work, go to:

http://www.aero.und.edu/multimedia and click single engine inoperative trainer.

This is a pretty neat program - it lets the student change various factors (weight, cg, etc), and shows it effect on the aircraft.

What about Gear Retracted and Aircraft Airborne and out of ground effect?

Man - that is very cool. Somebody spent a lot of time on that trainer...

WTF just happened?

Takeoff Configuration

It is just a simple memory aid to help remember what raises and lowers Vmc

That's a really cool little thing. Unfortunately, you can't slow it down enough. It would be really cool to let it roll.
