PLEASE EXPLAIN IF ABLE

[FAST FLIGHT OPTIONS LLC]

Could someone with a better understanding then I regarding Mooney Aircraft systems please explain this excerpt taken directly from my POH if able....

 

A spring loaded interconnect device indirectly joins the aileron and rudder control systems to assist in lateral stability during flight maneuvers.

 

I’m wondering if this means that I’m not having to use as much rudder input as I might have to in a different aircraft when doing maneuvers like lazy 8’s or even when just executing a normal coordinated turns?

 

Thanks

Nick--

I'm no A&P, but when you deflect the ailerons there is some rudder movement. No, not as much as in a Navion. Try some turns with your feet flat on the floor, then repeat again with rudder input. Normal in-flight turns, course corrections, etc., require very little rudder [if any] in my C. If you give manual rudder input, the total travel should be the same as in a plane without the interconnect, as it will give some input--you will just have to give it "more" for steep turns, etc.

Like the PC system, this is a safety thing and a stabilization thing. Yes, I use rudder in the pattern; no, I don't hold down the PC disconnect, I just override it. The rudder inputs I give just add to the amount the plane puts in by itself.

Many different makes and models of aircraft have an interconnect between the ailerons and rudder to help pilots maintain coordinated flight when making turns (keep the ball in the center), and some work better than others.  For example, start a right turn with some right aileron, and the spring interconnect applies a little right rudder at the same time.  (As a side note, if well coordinated without any pilot input, this type of aircraft can be somewhat difficult to do primary instruction in, as the importance of rudder is masked by the interconnect system, and may contribute to pilots that are trained to have lazy feet.)  Because it is a spring interconnect, you can apply more or less rudder regardless of the aileron input, so there is no problem with doing Lazy 8's or other maneuvers.  Some aircraft have no interconnect.  Occasionally pilots move from one aircraft to another and are surprised to find that they need to use a little more rudder, or a little less as the case may be, to keep the ball in the center.  I rarely think about it any more, and just fly each airplane with whatever rudder is needed.

After going through my owner assisted annual and looking at those springs they are relatively light.  While flying I tried to see how much effect they have and it was not much if any but that was close to cruise speed.  On the jacks you can easily see the interaction between the ailerons and the rudder.  I’ll have to try again at MCA.

Sorry fantom that was my post somethin strange is happening here.

Note the movement of ailerons on the ground when you input the rudder pedals left and right during taxi.

 If your PC is on, opposite direction...PC ground check.  If PC is off, interconnect check, same direction.

Sorry...I know you don't need the explanation.  I thought it might be helpful for others that may have PC...don't panic, your inteconnect springs are not reversed!

To be clear, I probably should have started out by saying: "For those of us flying the older Mooneys..."

The aileron pushrods run right next to the rudder pushrods in the belly.  The spring connects the two, so when one moves, the other is moved with it.   Thats why landing in a corsswind is a pain. You have to fight that spring.

On the Mooney I am flying, it was recently discovered that the rudder push rod does not secure during the annual inspection -- as if it has room to move around a little bit more than normal (perhaps left to right). 

Should there be some sort of brace / bracket or tension adjustment?  Sorry that I do not have photos, video, or better explanation --- Once I get more details, I will share, ,but I am concern what it could be.

When I am taxing and flying all seems well.  

Just trying to get some more understanding.

Thanks.
