My previous post wasn't very clear, It appears that my Challenger is reporting traffic 400ft low. I have flown near other aircraft and verified that ForeFlight is correct and the efis is reporting low. I have 2 altimeters in the plane and they are reading within 10ft of each other. I have talked to ...

I seem to have a ADSB altitude discrepancy on my Challenger Lite. The traffic shows up 400ft lower on the EFIS then it does on my IPAD. I have had the system installed for several years and the two units used to agree. I am using the Uavionix EchoUAT and the skyFYX via serial port to the Challenger ...

I believe there are instructions in the pdf file for importing google maps and georeferencing them. The navidata comes from the database tables. If you are trying to add maps to the Gen3 I would use Mapmaker2.

The navidata.ewd file contains airport and obstacles information not maps. If you are trying to make map files you need to use MapMaker2.

Here are the instructions if you are in the US and want to build your own Navidata.ewd that contains the radio frequencies: 1. Install Mgl Central 2. Follow instructions on page 10 of MGL Central.pdf Download the latest files from the FAA 1. Faa cifp data https://www.faa.gov/air_traffic/flight_info/...

I am missing the frequencies as well. I believe I remember reading that they were no longer merging the data from www,navaid.com because the data was no longer being updated and some of the data was inaccurate. Here is the excerpt from page 10 of the mgl central database tool instructions: As of wri...

So the function is working as intended but the text should be track instead of Brg. Thanks for clearing that up for me.

I have noticed that my GPS BRG does not update real time. If I Re Track the value will update. The source is track to waypoint (mag). Is this a bug or is there some strange reason this only updates when re-tracked? I know I can change the source to GPS heading to waypoint to make it update real-time...

I didn't find anything on the memory chip or the flip-flop. Is the CPU card field replaceable or is it soldered to the baseboard? I need to get it repaired. If I can swap the card that would be great if not I need to send it to Matt.

I will take a look at it after lunch and let you know what I find. I am familiar with tin whiskers but only experienced issues on the dense BGA parts. I did a quick inspection of the cpu card when I replaced the flashcard and the solder on the smt parts looked good. I will take a better look at the ...
