Digital Aviation Piper Cheyenne (FS2004)

Recommended Posts

Does anyone know if there is an update for this aircraft. I have had it for a couple of years and have NEVER been able to get the GPS to hold a trackline. It has a lighted, green toggle switch that says, "toggle NAV/GPS" and it makes a clicking sound but there is never, never an indication that it has switched from NAV to GPS. Does anyone have this aircraft and can make the NAV/GPS switch work? I bought it from Aerosoft. Thanks jerrycwo4

Please explain a bit more. I do not understand what you are trying to get across to me to make the "GPS" switch work. No, I never use the NAV1 for anything other than to load a ILS freq. Am I suppose to load a freq into NAV1 to make it hold a course on GPS? I've been doing it this way for 10 years without any problems until now. Please explain how to make the GPS switch work. Thanks for the effort to help. jerrycwo4Would you please add a link for the UPDATE? I was looking for it yesterday and could not find it for "Digital Aviation" or Aerosofy.

I don't have the Cheyenne but this is how I read it:This seems to be a peculiarity of the Cheyenne, since obviously other FS2004 aircraft don't do this.If you have an ILS frequency in the NAV1 radio - the NAV/GPS button will be impossible to switch to GPS. If an ILS frequency is in NAV1, it will stay suck on NAV. So what you need to do is tune the NAV1 to a non-ILS frequency... ILS Frequencies are between 108.1 and 111.9 with ODD decimals. I believe the NAV1 in FS9 defaults to 110.5 which is an ILS Frequency. Change this frequency too something else that is NOT an ILS frequency, and the GPS button should work. Like I said I don't own the cheyenne, but that is how I read that link. Try tuning in some different frequencies (not between 108.1 and 111.9 with an odd decimal place) and see if the GPS button starts working.

With regard to the update, it is available at the Aerosoft site by selecting the updates link on the lower left side of the home page and logging in. Select the Cheyenne on the updates page and it will take you to the update link for the aircraft.DJ

Samulis md82 panel has this peculiarity as well, you must detune nav1 for gps tracking to work.regards,Mark

You need to have a VOR tuned in and it will probably track to it. GPS is not to make an ILS APP. Have it set to NAV(off) and GPS(on) to track a VOR.Hope this helps....Dick ReaMCA 372

that's not what he was asking - he was saying that the autopilot NEVER tracks the GPS track, ever. it's because of the quirk described above.

I tuned a non ILS freq into the NAV 1 and now the NAV switch will chaNGE in the GPS, BUT it still will not follow my track line. Any other ideas? The auto pilot is on, the nav switch is off and the GPS switch is on with a non ILS freq on NAV 1. jerrycwo4

Still not working. I have it in the GPS mode, with NAV off and the freq of the NEXT VOR on the trackline loaded into the NAV1, but it still will not track. This was a very advanced GA aircraft and I know that a lot of people besides me that MUST have it and can make it fly a trackline. Please tell me how YOU do it ! Thanks. jerrycwo4

You must make sure the NAV 1 radio is not dialed into a valid ILS/VOR frequency, so set it to 108.000, that's where mine is, and then put the GPS switch to on. It's the switch that's blue and green and toggles ILS/NAV or GPS. Also, you MUST have the Flight Director turned on (autopilot panel) and set the AP to NAV. The AP will not track the flight plan if you're too far away from the track line, so if ATC or your take-off places you too far off track, you'll need to use heading mode to line it up. Then place it to NAV in the AP and make sure it's still set to GPS on the main panel. Also, remember to use the AUX button on the GPS to activate your flight plan once it's booted up.

Reading this post it is quite clear you never bothered to read the manual which explains how to get the nav/gps switch to work, how to load a flight plan into the GPS (it won't track if you don't load the plan into the GPS) and how to operate the autopilot. There was a great deal of programming and thinking outside the box (Microsoft box) to get many of the operations in this aircraft to perform like the real aircraft does and not the simplified MSFS operations. Having something this complex does require some reading to understand how to get the most enjoyment out of it.

you are quite correct. This is a very complex aircraft and I did find the manual for it and it takes a LOT of programing to get it to work. I spent about 2 hours working with it but so far I cannt get it to track. I'm taking a breather from it now but will try it again later. jerrycwo4
