HelloDoes the real JS41 have a FMC AND GPS system? Is it even close to the default FSX? If so where does the GPS go on the panel?Jim V

The FMS and GPS fitted to the J41 are one and the same unit. The Bendinx King GNS-XLS is a flight computer that has an in-built GPS receiver but can accept other inputs too. There is no other GPS fitted to the aircraft, and certainly nothing like the defaults. More details at: http://www.seaerospace.com/king/gnsxls.htmIf memory serves me correctly there is the facility to pop-up the default GPS in the J41, but if they're isn't it's fairly simple to add in. But you wouldn't be able to place it in the cockpit, it would just be a pop up.Chris.

OK I see, well I can't imagine trying to navigate around the FSX world without a GPS so I'll have to use the default FSX model then. It's an instrument you can pop up through the menu tab or shift 1 for my system. Its a shame that something more similar to the real Bendinx King unit couldn't be modelled for the PMDG verision of JS4100 , but I would imagine it's a limitation of FSX.Thanks for the responseJim V

The JS41's FMC is all you need to fly anywhere you want. Are you just not use to PMDG's aircraft or FMC style computers? If you really want the GPS so you can look at the moving map or whatever then use it. The default GPS as you know is in the menu under View, Instrument Panel, GPS and it will pop up the very generic default gps, but I still dont understand the need for it. Also, for future posts you should sign your full name per forum rules.http://forum.avsim.net/topic/245586-you-must-sign-your-full-real-name-to-posts-to-use-this-forum-posts-without-names-will-be-deleted/Whenever I fly most things in FSX I NEVER use the GPS. If in lighter aircraft I fly by a combination of visual and instrument but mostly VOR to VOR. In PMDG aircraft I use the FMC. It sounds like this is your 1st advance simulation and perhaps your new to advanced FMC/CDU operations.

Hello, Thanks for your response and yes I am new to FMC flying. Maybe I'm missing something, but there is page after page of navigation data on a GPS unit, even the default FSX GPS that I don't see on the FMC, so maybe I'm missing something. For example, if I need to make a unscheduled landing at the nearest airport, where in FMC can I get nearest airport data and ILS frequencies? and the display does not give me the same runway orientation data as the GPS unit does? The airport just shows up as a star on the display.Thanks,Jim Vasto

You are not missing anything - the default GPS unit does give you some kinds of information that is unavailable with the FMC in the JS4100. This could be because the real FMC does not have eg. "nearest" pages, or these pages may have been omitted in the PMDG version.Assuming that the PMDG FMC is correct in this respect, choice of diversion airport on the real airplane would be based on preflight planning and ATC coordination.

Hi Jim, if You're interested in that kind of info You should probably check AivlaSoft EFB. FMS is not information but navigation oriented tool, it's quite simplified in J41 beside to bigger aircrafts but get's the job done.

Its a shame that something more similar to the real Bendinx King unit couldn't be modelled for the PMDG verision of JS4100 , but I would imagine it's a limitation of FSX.

To be fair to PMDG, they did a fairly reasonable simulation of the Bendix King GNS-XLS, especially considering the J41 is something of a "lite" product there are only a few bits of the system missing (if memory serves correctly, I think the HOLD page is the biggest omission). Never the less, the GNS-XLS as modelled is all you should need for navigation, and if you require a moving map such functionality already exists in the product. The reason there is nothing similar to the default FSX GPS in the cockpit is because that's how the real aircraft is!To get a moving map on the EHSI:Once you have a route programmed in the FMS, keep pressing the FULL/MAP button on the glareshield until you have an arc (rather than a circle/rose) type display in the EHSI, then press the LNAV button which is also on the glareshield and you will get a moving map, although it doesn't have as much information as the default FSX GPS unit. This is how they fly the real J41s (if they chose to use the FMS at all). You can see the moving map in the bottom of this picture: http://1.bp.blogspot.com/_POkhEbJFK1g/SpcgwWR2yzI/AAAAAAAAApw/HJtvmScF0_Q/s1600-h/PMDG_J41_EHSI_EADI.jpgChris

Ok, thanks for the replies, one item that would be helpful is knowing the ILS frequencies for the various approaches that you can load into the FMS. I know you should always have a navigation chart of the airport and all the runways but does the FMS give you the Nav frequencies somewhere?Jim Vasto

Sorry Jim, I meant to get back to you yesterday but others have already covered everything (except your new question that I'll hopefully touch on). Most PMDG users are normally looking for as close to the real thing as possible, so normally refer to the charts. I print mine out, or view them on my laptop. There is also the use of 3rd party apps like an EFB but the downside there is running in windowed mode in FSX.I'm in the opposite position you are haha. I just bought an addon for the GNS 530 GPS and have a ton to learn since I never use it. It's for a much lighter AC, and not a PMDG. I'm wishing we could trade knowledge right now.

It does not, because You as a pilot should be familiar not only with the ILS freq but with whole approach, all minimums, missed approach procedure, navigation aids etc. Honestly, I have no idea what information is included in GPS but I can't imagine landing my J41 without printed chart on my knees or EFB on secondary monitor.

This could be because the real FMC does not have eg. "nearest" pages, or these pages may have been omitted in the PMDG version.

Ehm? Click D-to twice and you got a nice nearest-airport page.. :(
