Low Pass 12-17-2018 08:05 PM

Hello (Garmin) Steve,

I've installed a GDL 82 and am working out the bugs. I've flown the plane a couple of times and am trying to download the "assert" file to try and understand what the condition of the outgoing reporting might be. First question is, what does the "assert" file report?

Second issue. I've downloaded the file to my notebook pc and tried to extract the information. It appears to be a compressed file. It also seems to be password protected. Is there a Garmin created password I need to know? Or is this something related to this notebook pc?

Thanks

I don't know what an "assert file" is, but after I fly - if I want to check the performance of my GDL-82 - I request a ADS-B Performance Report. The FAA sends then via email within 30 minutes. There shouldn't be any red squares on your report if your unit is working properly.

GDL 82 install
 
Does the GDL 82 need to be oriented in any specific way or just wherever it fits best? On it?s side, upside down, etc does it matter?

Hello Bryan,

The assert log has no value to a GDL 82 user.

We agree with John that the best way to find out how your system is performing is to request a PAPR report from the FAA. We do this anytime we make a change to one of our aircraft.

Thanks,
Steve

Hello Oly,

The GDL 82 may be mounted in any orientation.

Thanks,
Steve

I installed my GDL82 behind the panel vertically on one of the ribs. The GA35 antenna is mounted under the cowl attached to the fire wall on an aluminum platform. I drilled a hole in the fire wall and ran the cable from the GA35 to my transponder.
Did my ADSB verification flight and passed on my second try. First try failed because I did not spend enough time in ?rule? airspace.
When you get your report from the FAA after doing your verification flight you will receive two attachments. One will tell you how,your equipment operated. The other will tell you if you passed or failed.
I really like my installation because nothing can be seen. Nothing on the glareshield and no additional antennas on the exterior

What model RV, please? I have a friend with an RV-12 who is getting ready to install a GDL-82 and is looking for a good place for the GA-35 antenna. I guess you're probably aware that the installation manual specifies an ~18" dia. ground plane (6" from the perimeter of the antenna), but these smaller ground planes seem to work. I wish Garmin would elaborate on what size is really needed and why.

Antenna location
 
Don't know if relevant to the -12 but my -7 antenna is mounted on the dash with the 6ft of coax coiled up underneath. Just reviewed my latest FAA PR and once again zero errors.

Mine is an RV9. The aluminum platform the GA35 is mounted on is just slightly wider than the antenna and barely as long.
