    Seneca Autopilot

    Capturing a glideslope from above is within the ability of the majority of modern transport category aircraft. In the REAL world, more often than would be commonly expected, commercial flights have to deal with what in turn ATC controllers have to deal with re the realities of too many...

    HDX Classic mix

    Stating the above in a different way: Right now, a mix of Classic and HDX will operate together, provided they are on the same software version. Dynon reps reluctantly admit as much when talked to one-on-one at Oshkosh. In the very next breath they caution that at some point the software...

    EMS Fuel tank calibration

    Do it in the way that is MOST accurate. Drain the fuel. Now you know what the tanks REALLY hold and what zero fuel left available truly is. Yes, it is more work, but you will not have any doubt as to whether or not any kludge is accurate. Do it once. Do it right.

    VNAV, Autopilot coupling, LPV and Avidyne IFD

    Skyview will only capture GS from below, so if approach control keeps you high for too long and you are forced to intercept the GS from above, that intercept will have to be hand flown. To get the FD or autopilot to arm for VNAV, you need to be on the last leg before the FAF. Just because you...

    Planning HDX1100's and Avidyne GPS/NAV/COM - how many GPS antenna and where?

    As said above, the Avidyne and Skyview each need their own antenna. Keep in mind that the Dynon unit is both an antenna AND a GPS receiver. The wiring for the Dynon units is only for power, ground, and data. There is no antenna cable for the Dynon GPS-2020 or GPS250. Skyview uses position...

    SA does it again.

    A very simple way to verify that the wright to the USB is indeed happening is to open Task Manager and click on the performance tab. It shows (among other things) all connected drives and their read / wright activity. It also shows connection speeds. I routinely update 2 small thumb drives at...

    Yoke Mounted Autopilot Disconnect Switch Setups

    Just my take on things, but toggling off an autopilot without having a firm grip on the stick / yoke at the moment of disconnect is looking for trouble. It's entirely possible - and more than just occasionally happens - the autopilot is covering up a mis-trim condition to some degree in which...

    New Garmin GNC 215

    I'd suggest you research very carefully with an experienced tech who knows the 175, the 215, and HDX systems in and out and has first hand experience getting the G stuff fully functional with SkyView. The name 'Dynon' appears nowhere in the interoperability charts published in the ads for the...

    What is the better IFR navigator to interface with Dynon HDX?

    Both the Garmin 650/750 or the Avidyne 440/540 (or 550 which adds an AHRS board if you want an SAI built in) will do the job nicely. As stated above, preference very well may be a function of your previous experience. The Garmin interface is largely touch screen only based and more often than...

    SYSEVENT 20, HDX screen shut down during instrument approach

    It is this realization that crashed screens indeed can happen that prompted me to include a standby ADI when I planned and installed my full IFR upgrade several years ago. I adopted the worst case mindset of what would I do if one screen crashed and, since they are networked, it somehow managed...

    Which Direction for IFR set up?

    It's not really clear (at least to me) in your post whether you want to keep the D100 and add to it or if you want to upgrade to a SkyView system. Which is it? Nice T18. Ken

    Auto pilot panel - helpful for a VFR airplane?

    Also, the AP panel eliminated the need, in my plane, for a switch that selected which stick's - left or right - trim switch was enabled. With the panel, both trim switches are enabled, but the left stick input overrides a right stick input if both switches are activated at the same time. I use...

    SA database problem with cycle 2401 - updated (resolved by SA)

    I also was lucky enough to get an SA lifetime subscription back when they were still sold, and I got BOTH alert emails. Both the first alerting to the problem and suspension of downloads, and the second one alerting to resolution of the problem. Note: For reasons way beyond my knowing, I...

    VNAV Arm

    I believe that to allow arming the VNAV mode of the AP to capture the glideslope, you must be on the last leg TO the FAF. To only be able to arm AT the FAF would make smooth transition to a stabilized descent much more difficult. Once armed, the VNAV mode will proceed to engage once the...

    Localizer is way off on the Dynon HDX HSI from SL30 Signal

    To enlarge upon and, for some, perhaps clarify the above: When tracking a VOR, the number in the course window matters. If the pilot changes the course, the CDI needle deflection will also change because the displacement of the needle represents how many degrees you are displaced from the...

    how to add an additional temp sensor?

    Do you mind sharing which battery you are considering? Is it Li-FePO4 or Li-something else? Since it has no BMS, how do you plan to keep the individual cells balanced and protected from deep discharge? I'm genuinely curious.

    how to add an additional temp sensor?

    Lithium batteries do indeed need to be monitored, preferably by an integrated BMS (battery monitoring system). To be precise, that wire from the EarthX battery does not send numerical temperature data.. The wire coming from the battery is a way for the BMS circuit board that is part of the...

    Updated D10A in the pipeline??

    Just a thought: The G5 is indeed a bit dated, but it is still a very capable unit. Consider: - One of the least expensive SAI solutions, especially if you can use the experimental version. - Besides full pitot static information, it can also accept RS232 inputs from your IFR navigator to...

    Adahars Failure?

    I 100% agree w/ Marc. If flying IFR, dual ADHARS is a must for safe operations. I consider a standby ADI, such as a G5, a D10, a D30, or similar to be essential as well. There needs to be a referee to as to which of your disagreeing ADHARS is telling the truth in a timely manner. An IFR...
