This might be a stupid question, but is the intercom switch in the ALL or CREW mode? If the intercom is in the ISO mode, then I believe what you are experiencing is normal, as only the pilot can transmit on the radios when the intercom is in ISO mode. I'm in the process of troubleshooting a very similar issue with a Sigtronics SCI-4 intercom, but in my case transmitting from the copilot side works fine. I cannot however transmit from the pilot side when the intercom switch is in the ALL or CREW mode. The radios appear to be transmitting as the TX indication appears on both radios, but there is no voice heard on the receiving end. However, if the intercom is in ISO mode, then transmitting on the pilot side works correctly and sounds great, which tells me the wiring is okay from the pilot mic jack and PTT switch to the intercom, and from the intercom through the aux mic jack and to the audio panel. I'm leaning towards the intercom being defective, which was installed new a couple of weeks ago. Not sure what you mean by this statement. Can you elaborate? Also, can you confirm the intercom audio is working normally at all seats? Pilot and passengers can hear copilot, and vice versa? If so, then that would indicate the wiring from the copilot mic jack to the intercom is good. Jim K.

That’s correct for the Skywatch TAS/TCAS system but not for Stormscope. The only way to interface with the WX-500 is through the controlling display.

The fault log cannot be cleared. The 20 most recent faults are shown in the fault log and cannot be erased. In your unit code 16 has occurred twenty times over the past approximate 1 hour (53 hours 16 minutes to 54 hours 24 minutes). Kinda odd to see a 9 year old unit with only 54 hours of operation!

Thanks for the pics! This is very helpful! Error code 16 is the reason the unit is failing, and a code 16 is caused by either a bad antenna (very rare) or a wiring problem in the antenna cable. Most likely there is a short or open in the antenna cable. A continuity check should be performed on each wire in the cable to ensure none of the wires are open or shorted. Processor s/n 97420 was manufactured in 2011 and has never been returned for repair. Hope this helps! Jim

Can you send me a pic of the Stormscope Configuration Page from the 650? I’m curious to see if the data displayed on that page matches the actual configuration (strapping) of the unit. Also, what is the serial number of the WX-500 processor? I can look up the history on that unit and determine if it had been returned to L3 for a serial comm problem in the past. Feel free to email me at jim.keeth@L3Harris.com.

The first step in troubleshooting a WX-500 failure is to retrieve the fault codes from the WX-500 fault log, and that is accomplished through the display that is wired to be the master control for the WX-500. Hopefully the GTN650 is wired as the control, as the GTN does a good job of displaying the fault log for the WX-500. I don't have any experience with the GI275 and WX500 combination to say how well that interface works. The Stormscope data is accessed in the External Systems page in the GTN's configuration mode, and section 5.5.4.2 in the GTN installation manual has a good description of how to access the fault log and how to view additional data for the WX-500. If you can't view the Stormscope data then there is likely a serial communication problem between the WX-500 and the displays. It is very important that the RS-232 RX at the WX-500 is coming from one display only, which would be the master control display. FYI...L3 sold the Stormscope product line to Extant Aerospace last year. Hope this helps! Jim

I could walk you through the process to update the software. It's not too complicated and depending on your laptop and USB speed could take as long as 15 mins. You would need a Windows 10 computer, the Lynx software tool and files, and a USB to mini USB cable. Shoot me an email and I'll send you some info early next week. Jim

Hi Steve, Nope, not a wifi configuration issue. ForeFlight does not display the active traffic targets, but I believe they are working on correcting that. Jim

Hi Derek, I think I can help you out. Most likely the WiFi dongle needs to be reconfigured, which is very easy to do. You'll need a Windows 10 laptop and a software tool. Send me an email (jim.keeth@L3Harris.com) and I will send you the tool and instructions. Jim

I'll confirm the bench fee and repair pricing this week, but I'm fairly certain the bench fee won't apply if it is determined that the processor requires repair. That's been our normal repair philosophy for quite a long time. Regarding the picture of the processor, the only LED that is a concern is LED 7, and that LED will be on when the system is in a failed condition. However, that doesn't necessarily mean the processor is faulty. You could have a bad antenna or antenna cable, or it's possible the controlling display isn't configured properly for WX-500 operation. Do you have a picture of the Stormscope fault log from the controlling display? That would be very helpful for troubleshooting the system. Jim

What fault codes are being recorded in the fault log, and is the WX-500 in a failed condition at all times, or only temporarily? Was the WX-500 failing before the panel rework? Also, it’s not a bench fee AND repair. It’s a bench fee OR repair fee Jim

Yes the Lynx NGT-9000+ does send the active traffic targets out on the wifi to be displayed on the apps. However, last I checked, which was a little over a year ago, ForeFlight only displayed the ADS-B targets and not the active traffic targets. Don't know why that is, as most of the others apps have no problem displaying both ADS-B targets and active traffic targets from the NGT-9000+. I would recommend you contact ForeFlight and ask if their app will display the active traffic targets (TAS/TCAS) from the NGT-9000+. My information is dated, so it's possible ForeFlight has finally implemented this in a recent update to the app. Hope this helps! Jim

TargetTrend is exclusive to Garmin products because they designed, developed, and patented it. The Lynx NGT-9000 is the only unit on the market that offers ATAS (https://www.faa.gov/nextgen/programs/adsb/pilot/atas/), plus a built-in color touchscreen display to see the traffic and weather, plus a built-in TAS/TCAS processor, plus diversity, plus terrain. I'd call that feature rich!

FYI...as of the start of the year, ATAS traffic alerting is included free of charge from L3.

No. The NGT-9000+ outputs 250W maximum for the transponder function and the active traffic function. The 9000 w/TAS doesn't output any more power than the 9000 w/o TAS.
