When I turn left or right only my spoilers raise slightly, and no movement from the ailerons whatsoever. anyone elso noticed this??-darren

>When I turn left or right only my spoilers raise slightly,>and no movement from the ailerons whatsoever. anyone elso>noticed this??>-darrenDrawing on my vague memory, I believe this is correct behavior, and what follows is my reasoning.On a large wing like those used for transports, there's always a trade off between building in strength and keeping weight down. With an aileron out at the tip of that long wing, a little deflection can produce a large roll at the center, but the wing's got to be strong enough to take all the force.By using the flight spoilers to assist the ailerons, you reduce the forces on the wings - rather than large forces at the ends of the wings, you have a distributed force across them. Because of this, at normal (high) flying speeds, very little aileron control surface movement is required for normal banking. If you move the control surfaces while parked at the gate, you should see a more "normal" looking movement.The Caravans I fly use a similar system - when an aileron is deflected more than 5 degrees upward, the spoiler on that side also deflects proportionally.

Hi Tim, For the same reason that you explain, the system of using the ailerons and spoilers is called spoilerons.BoazPS. Thanks for the great tutorial. It looks rock solid. Am looking forward to actually flying it.

Sorry, entered in error... More info pending...;-)Cheers.Ian.

"When I turn left or right only my spoilers raise slightly, and no movement from the ailerons whatsoever. anyone elso noticed this??"I believe I commented on this a while back, Darren, but.... don't let that stop you (I needed to know that I wasn't the only one having problems ;-)).I've just been reading throught the NG Maintenance Manual and there appears to be hundreds of pages on the rigging of flight controls... so the information hasn't been easy to assimilate. For the spoilers, the deflection is given in degrees... and for the ailerons, the deflection is given in inches, so it's a bit hard to compare the two.Basically, however, if I'm interpreting the manual correctly, I see that the ("Flight") spoilers should start to rise when the control wheel is turned to 11 degrees....each spoiler has a different start position, but may not stow completely until the control column has returned to 5 degrees from neutral (although the tolerance is plus or minus 3 degrees).For the ailerons, I couldn't find out at which point they begin to move, but I would assume that it would be whenever the wheel is moved from neutral (allowing for cable tension/slackness and actuator response)....and certainly well before 11 degrees! Note here that there are no inboard/outboard ailerons on the 737, and therefore no outboard aileron lockout as on 767's, 747's, etc when the aircraft has reached a certain speed and/or when the flaps are up. Further info:There are 12 spoiler panels on the 737, i.e. six on each wing. The spoilers are numbered 1 through 12 from left to right. The "Flight Spoilers" are the #2, #3, #4, #5 (on the left wing) and #8, #9 and #10 & #11 (on the right wing). These move when the control wheel is turned in flight. The Ground spoilers are the most inboard and outboard spoilers on each wing and are not used for roll control.When the wheel is being moved from neutral, towards fully clockwise/counterclockwise, each spoiler will rise at different times, at different rates to different angles for a given control wheel input:E.g. At 30 degrees control wheel CCW movement the #2 spoiler will be at 3.5 degrees, the #3 at 5.5 degrees and the #4 and #5 at 10.5 degrees.The #2 and #3 spoilers go on to a maximum of 33 degrees at 87 degrees control wheel movement. The #4 and #5 spoilers go on to 38 degrees. Returning the control wheel to neutral, the #4 spoiler should start to move down before the wheel is moved past 70 degrees. Oddly, the manual says the #4 spoiler should go back down completely when the control wheel is at 5 degrees (+/-3 deg)..... somewhat different from when it began to rise (11 degrees).Full aileron UP deflection is around a mere 4.59 inches. Full DOWN is even less at around 3.87 inches, so this may be hard to spot in PMDG.Having the ailerons move before the spoilers I thought was a basic safety feature. E.g. in an engine out scenario after V1, you need to keep the aircraft flying straight using the rudder... If you use too much control wheel input, the spoilers come up and this generates a loss of lift (not what you want when you have lost an engine!).Hope this helps?Cheers.Ian.
