I had an issue with vibration when I first bought my aircraft that had 300 hours on it so don’t know why it had not been fixed. My fix was to strengthen and stiffen the mount the adahrs was on. I was tempted to use rubber mounts but it was not necessary and probably not advisable either.

Hi 1) I have installed two and yes you only need one password etc. Dynon say in their documentation two are needed for system redundancy 2) I have installed the two wifi dongles in one of the two ports on the back of the screens. If your back is not up to twisting under the panel why not take...

I am using a 261 transponder in New Zealand so it’s definitely not US only.

I guess that the fact that there is no two way communications says that there could be a wiring issue. If it were me I would be checking the two data wires are showing continuity and they are in the correct pin holes at both ends. Yes those were the jumpers I was referring to. I have to say when...

Have you connected a gps 2020 if so have you set that up as the GPS source. I notice in the manual that the transponder shows offline where they talk about setting up the GPS source. Provided the wiring is correct and the jumpers are all in place then it has to be a settings issue in my mind.

What does the serial port information show?. Is there data going backwards and forwards, that is are there data blocks being transmitted and received. I would suspect there could be an issue with the wiring. I bought my 261 from the USA and am using it in NZ so I don’t think there will be a...

What about moving pin 1 to pin 2. I don’t know if they are just bridged internally or if they sense independently but could be worth a try.

Pleasure sleep well

Stan have you tried reconfiguring the network? Not sure but this may be the same issue that some have experienced with network devices dropping offline after the update. The fix is to physically remove the device affected from the network reboot and reconfigure the network. Then power down...

The unusual values when you disconnect an egt probe are interesting. I was fault finding an egt probe problem the other day. When we disconnected the faulty probe we had a red X on that egt display. We decided to swap with the #1 egt and found when we disconnected that one the temperature...

i had exactly the same issue. All working well one day then the next fuel level zero. After experimenting with a bent stick in the filler hole I found the sender had developed a dead spot mid range so no amount of re calibrating would have fixed it. Replaced the sender with a new one and all well.

Don’t have an answer but reading the manual it seems the system calculates guidance for the flight director and the autopilot follows the flight director. So I would have thought it should not matter for alignment on the runway as the flight director should be guiding you to the centre of the...

A quick look at the figures shown and a couple of minutes with a E6B shows that there is a wind correction angle of 23 degrees and a ground speed of 132kts. I suspect the information shown is correct.

A bit more info on my system fix. The re-imageing worked well and everything seemed to be going well. I realised when I went for the first flight that I had not loaded the hi-res pacific database. I did 4 error free flights and decided to update the database. It failed each time I tried it with...

No idea that was what I was wondering as well. The approach I have been told to take is to reimage the drive. I would be interested to know if a fdisk , chkdisk or the Linux equivalent type utility is run on the drive before the new image is laid down on it. However I will follow the...

i have had great contact from Don at Dynon and he thinks there may be an issue with my hard drive that may have caused data corruption. I have been given some links to software to have a go at reloading the software to see if that will provide a solution. Ultimately I suspect it will have to go...

Hi all Anybody any idea what causes a system event 11. I was attempting to update to the latest software 16.0.04 when it produced a Event 11 message and told me to contact Dynon with a diagnostic file which I have done. The problem now is the Screen will not boot up at all and stops on the Dynon...

Yes you can and you can move things around if you prefer sensors displayed in a different layout. Download a copy of the installation manual and it explains it all in there. Look for the EMS section.

Hi I have just noticed the same problem. I downloaded the data files onto the USB I have my chart files on. after looking at the data files I went to load the new chart files on the drive and it said it would take 3 hours. I discovered the drive thought it had something like 13k new files on it...

As mentioned previously check the static ports are clear and you are not using static air from inside the aircraft. I discovered to my horror after an avionics check that a T fitting was broken by the engineer and once airborne discovered the pressure inside the cockpit reduces and causes a...
