There are three features that appear in the AOM as if they should work in our J41, but they've never worked on mine. Here they are. Is it just my machine or have others found the same?1. The green and white panel lights indicating who is Pilot or Co-pilot. They should only present one of each at any time: one person being Pilot, the other Co-pilot. When you toggle the switches on my J41 you only see BOTH as Pilot or BOTh as Co-pilot ...2. At cold and dark startup, the TEST button is (I think) supposed to turn the EHSI into a countdown indicator so you can see when the inertial systems will come alive. The button is the same as the DH setter (which functions OK). But TEST never does anything on my machine.3. The TURN Knob on the AP console. Its true purpose seems to be a bit of a mystery, but one thing's for sure, it does nothing on my J41!What's the story? Does anyone out there also find these features not to work? I'm not saying their absence destroys my experience. That would be to go too far. But since they've not been "redded out" by PMDG in the AOM, I was expecting them to function as described ...Thanks and best wishes,David

You shouldn't need a light on your panel to remind you whether you are sitting in the left seat (pilot/capt) or in the right seat (co-pilot/FO). That wouldn't make any sense, as it would be the same, every time.That button determines whose side has control over the mode control panel (autopilot functions, as there are some features on both the Capt and FO sides), ergo, only one side will be active: that of the pilot, or that of the co-pilot. The determination of this is at the outset of the flight when the crew determines (or scheduling determines) who is the pilot flying, and who is the pilot not flying.

You need to turn the Air Data Computer Test switch to position 1 or 2 in order to do this.

3. The TURN Knob on the AP console. Its true purpose seems to be a bit of a mystery, but one thing's for sure, it does nothing on my J41!

It is a wing leveler. Essentially, if you turn it a certain amount to the left, it will hold a constant bank turn to the left until you re-center it. I've never tried this function in the J41, so I can't vouch for its effectiveness.

Things working correctly depends on the user using/activating them correctly. The devil is in the details. In order to use things correctly, you must understand and operate on the detail level. I suggest re-reading the material.

Appreciate your post, Kyle. Sorry to sound so stupid, but ...1. Absolutely understand the function of the Pilot/Co-pilot lights, so I probably didn't make myself clear enough. Try toggling that (agreed) control-determing button on your own J41 a couple of times. What happens on each of the two lights? On mine both Pilot green lights stay on simultaneously, which my reading of the material suggests should not be the case i.e. whoever has control should leave the other guy without control and a Co-pilot white light, no? The AOM page refererence is Ch8.11.53.2. Again I did read the materials before posting, but honestly can't spot any locator-illustration for the Air Data Computer Test switch labelled as such, nor so far any obvious explanation about Switches 1 and 2 being required before pressing TEST. But - thanks to you - I am now coming to that view that it's the AHRS switch on the glareshield that needs to be at either 1 or 2. I'll give it a go next time ...3. It's clear what the TURN knob is supposed to do. But whenever I try it out, there's just no wings-level turn at all, no matter how long I hold the knob out of detent. The printed material doesn't really make it clear whether the AP has to be engaged or not, but I tried it both ways to not avail. That was the purpose of my question: maybe try it when you have a moment to see if it works OK on your J41.Thanks to you and all.Best wishes,David

No. The button will only display who currently has control. Don't think about it as pilot/co-pilot. Think of the 'pilot' as the left seat and the 'co-pilot' as the right seat, because that's what they are. If the button says 'pilot', then the left seat pilot has control over the functions, whereas if it says 'co-pilot', the right seat has control over the functions. Again, pilot is the left seat and co-pilot is the right. The distinction you are trying to make is pilot flying and pilot not flying. If I'm the 'pilot' position, I sit in the left seat (Captain). If I'm the co-pilot, I sit in the right seat (First Officer). This is a 100% of the time type of thing (except in certain circumstances: 2 captains on the flight deck being one). The buttons are only indicating which seat has control, not who is who, ergo the lights will show the same indication on both sides. Looking at the picture you are referencing in the AOM confirms this indication behavior. Reading the text on the next page (the more important part), further reinforces the above.

At the very least it's mentioned in the tutorial, but it should be in the AOM somewhere.

AP should be engaged, but the knob must be centered (in the detent) before the AP can be engaged.

Thanks again, Kyle. Still unsure about the TURN knob but will persist. However you have achieved a final breakthough with me on the Pilot/Co-pilot lights ... OMG ... NOW I SEE - and appreciate your patience !:( Best wishes,David

Glad I could make it understandable in the end, and you're welcome.I'll take a look at the turn knob tonight and see how that goes. I may video it and send it along if it works out right.

That would be great, Kyle. Much obliged!:( Best wishes,David
