Getting back to the original question it is interesting that photos show the Sikorsky R-4 doing ship trials being flown solo from the left seat. Other photos show the helo with a hoist on the left side, which meant the helo had to be flown from the right seat for the hoistee occupied the left seat once up at the door (Lateral C of G considerations aside). So maybe Sikorsky either set a convention by deciding on what side to put the hoist, or the side to put the hoist was dictated by the preference of seating position by the majority of pilots. Who knows?

On the fiddle or just a pansy ?

From Post #25 :
the advancing blade is on the right...and viola...most helos have the pilot sitting on the right side
"Viola" eh ? -

Maybe TankDriver ( or whatever today's name is ) is on the fiddle ...



... or maybe just a big pansy



( Both of the above are "violas" )

To wrap this thread up you will find the following comments re OnePercenter, tankdriver45, Angels 60 and his latest cattleflyer at http://www.pprune.org/forums/showthread.php?t=328287
I don't actually believe he's for real. Surely, no-one's that stupid.

Seldom have I heard anyone display the depths of their ignorance with such total conviction. The only downside is that there are others who might believe what he says through their own inexperience. The reasoning behind some of his statements would have made the Monty Python crowd very proud of him. He certainly sounds like he believes them himself and thats scary!
I have no comment.

There goes cattleflyer, who is onepercenter (who has been banned, along with the rest of his names), agreeing with himself.

This is necessary, of course, because no one else will agree with him.

cattleflyer - of course you agree with Onepercenter, because thats you. Do you take us to be absolute idiots? When you start talking to yourself, do you have idea what that is a sign of?

Thanks gr8shandini

Two questions:1.Do all props/engines rotate clockwise?2.How big are groscopic moments in terms of the requred balancing elevator power?

Keith,

Propellers rotate both directions, depending on the engine installation. This has no significant influence on elevator (pitch) operation with respect to the direction of operation, but it does have an impact on rudder requirements in single engine airplanes, and can affect the degree of assymetric thrust in multi engine airplanes.

With turbojet airplanes, the direction of rotation isn't of great significance.

With a propeller installation, gyroscopic forces aren't nearly as significant as a rotor on a helicopter or gyroplane. Gyroscopic forces are perceptible when performing an aerobatic maneuver or a rapid maneuver in an airplane, but the primary effect that gyroscopic precession has isn't on the pilot or aircraft, but stress placed on the crankshaft or prop extention (part of the reason that aerobatic aircraft tend to have significantly reduced TBO's on their engines).

Keith,

When I mentioned gyroscopic forces, I was referring to the WWI era when the early rotary engines actually had the crankshaft bolted to fuselage and the whole engine rotated. Obviously, this means that the forces were much higher than the modern configuration.

These theories probably come from a very good source...

Thanks ever so much for that one ... I really was in need of a lift in this constant chasing down of multiple personality sufferers .... my day is now much brighter ..


I did read a long time back a tale which suggested that the early military aviation side of things had pilots (often with a cavalry background) "mounting" their avian steed from the left .. which led to the LH seat thing in fixed wing aircraft ... no idea whether this is kosher but it makes some sense, I guess ?

Just been looking at "Flying the Hump" by Don Bownie and he talks of flying the Hump in C-47's solo (a practice that was conducted in the early days of the war) and guess which seat? The right side (no I don't mean the left, the right right). Thats where all the controls were.

I seem to remember an instructor telling me in the US that the PIC in a Heli sits on the right because he can follow the roads more easily...

This stemmed from the desire to prevent head on traffic conflicts when following topographical features. Ie always keep the road on the right.

This was of course right before he insisted on proving that I would not fall out with the doors off during tight banked turns....

I can't believe how many of you are taking the bait on this one... haha

Anyone who has flown a helicopter PIC from the left seat knows it's a real to manipulate the radios/nav. I never met anyone who preferred it that way.

A better question would be: Why would anyone design a helicopter with the PIC seated on the left?

Kawasaki KH4 is flown from centre seat.
Perhaps japanese pilots are more well balanced?

Ever seen a sling load?
Twice when flying with John Twit.
Once as it passed the skids and the second time when it was jetissoned.
