    182L Plan

    The HDX power needs to come on with the aircraft master. If you install a second screen, you can put this on the avionics bus if you wish. I have done a 182, and put both the screens on the battery master. The autopilot, transponder, radio's etc on the avionics bus. You will need a...

    Autopilot slow roll in flight

    This is from the Dynon autopilot tuning guide, a worthwhile thing to carry out if you haven't already. It will really make a difference to how well the AP performs. https://www.dynonavionics.com/includes/guides/SkyView_Autopilot_In-Flight_Tuning_Guide-Rev_F.pdf

    Power Off Shutdown Quirk

    Have a look at what your airspeed is doing when you go to shut down. I've seen it with Dynon and Aspens where the ASI is not zero, and prevents them from shutting down. I know it needs >40kts to automatically stay on battery power, but maybe it is spiking up and down? That's all I can think of...

    Dynon com low audio volume

    Did this just start happening, or has it always been this way? Do you just have the one com? Your intercom is working fine, so that says that the audio wiring to the jacks from the intercom unit is ok. I would surmise that you have a wiring problem between the com radio and the intercom unit...

    Certified Audio Panel/Intercom

    Everything I have installed from PS Engineering has been bulletproof. Just finished a PMA6000B into a Cessna 150L. It's one of the lowest cost certified models of the range, and it's great bang for buck. I've replaced loads of the old GMA340's with the PMA8000C units (usually due to the Garmin...

    Transponder error

    I have had this twice. You didn't mention if you are running a HDX and a Transponder 261/262, but assuming you are: On the ground, if you are getting the transponder error, go to set up screen (hold down the right hand two buttons. Go to SETUP MENU > TRANSPONDER SETUP It has a field there which...

    Push to Talk causes fuel flow to drop

    It's the actual transmit of the radios when PTT is keyed. He could fault find by turning off one radio, then the other to find which com is causing it.

    Push to Talk causes fuel flow to drop

    I'm looking at a Glassair which has interesting problems. Transmit on Com#1, the EGT's all rise about 50 degrees, release the PTT and they go back to normal. Transmit on Com#2, the altitude drops about 40 ft, release the transmit and it goes back to normal. The builder used the old RG-58 coax...

    Altitude with Aerocruze 100 / TruTrak when driven by the HDX

    There is a configuration setting in the Aerocruze for the type of EFIS it is connected to. From the config documents I have, the Aspen is PMAEFIS Type 1, and the Garmin G5 is PMAEFIS Type 2 I'm wondering what the Dynon is. I don't have an updated config matrix for the Aerocruze. Might be worth...

    Altitude with Aerocruze 100 / TruTrak when driven by the HDX

    OK, so it is SVS (sync vertical speed) Have you tried putting in ALT mode by pressing the ALT button on the Aerocruze? It should then allow you to select the altitude by using the alt knob on the Dynon knob panel. I haven't played with an Aerocruze hooked up to a Dynon, but I have installed a...

    Altitude with Aerocruze 100 / TruTrak when driven by the HDX

    When it is synched to Skyview, does changing your altitude bug on the SkyView change the altitude selected displayed on the Aerocruze?

    D180 and AP74 Mystery

    It sounds to me like the remote compass module (EDC-10A) is failing.

    XPNDR ERROR

    I had a cow chew a transponder antenna off a C210 recently :)

    XPNDR ERROR

    I just had this on a customers Dynon transponder. It's not the power in to the transponder, it's the power out (Transmit power) I replaced the coax and the antenna to test, but it ended up being the transponder itself, which Dynon replaced under warranty.' You can upload the log files to Dynon...
