Being aluminium, something like an RV or Zenith has the advantage of being able to use the built-in magnetometer capabilities of the ADAHRS. In aircraft such as the EuroFOX or Kitfox, with a welded steel fuselage, the built-in magnetometer is terrible and a remote unit is required. It is almost...

There's no requirement for the AP panel in order to enable expert mode. I use expert and have no AP panel. I think it would be slightly more convenient, on occasions, to have the AP panel but I'm quite content to use the autopilot without it. I'll normally set the altitude target before takeoff...

AoA warning works on the Critical Angle of Attack. It doesn't give two hoots where your flaps are. Flaps up, stall at X degrees Critical Angle of Attack, flaps down, stall at the same X degrees Critical Angle of Attack......which just so happens to be a lower IAS. The AoA works on differential...

Thank you for your comments, 362PC. I think if we go down the Dynon route then we'll keep it more simple and have just the one HDX display. Doubtful we'll have anything like the ARINC kit, as it'll never be used for IMC approaches etc. It is good to know that Foreflight can be used with Dynon...

That’s great info, thank you. Have you got the latest update and WI-FI dongle in your HDX? I’m not trying to be a salesman 😁 but just interested if you’re getting the drop outs with an older or newer set up. I’m no expert at all on Dynon WI-FI, as I use it for route transfer from SkyDemon (UK...

Hi All, I am in discussion with one of our customers about his avionics fit and the question of whether he goes for Garmin G3 or the Dynon HDX. As he is planning on doing some extended flying throughout Europe and the USA he is minded to equip his iPad with Foreflight instead of the more...

What was the MGL configuration for the sensor? If it's an active sensor then it shouldn't be too much trouble. Look for the sensor set up in the MGL menu and find out if it says something like 0-5v or 0.5-4.5v. It looks like it has one wire to it but I suspect you've taken one off the top of...

It is a good question because the serial ports just give you a lovely option to select something from the drop-down menu, instead of asking you to configure the input/output with a particular protocol. Having said that, the Trig transponder certainly mentions RS232, as does the GPS output from...

It's got the same RS232 Tx/Rx as the TY91, so I would be willing to bet a whole heap of ££££s that it does (despite the really bad exchange rate). Just hook it up to a SkyView serial port and configure as per the TY91.

How would it know which tanks you've selected? Surely you'd need some sort of electrical contact on the fuel selectors to signal the timer to start counting.

When I was 'playing' with my HDX (setting it all up after initial installation) the aircraft battery got a bit low and I lost some of the touch screen functions and, I think, some of the knob functions. There seemed to be some sort of minor 'brown out' that reduced some of the capabilities of...

If the backup switch is working okay (which connects EMS earth direct to airframe earth) then it sounds like an earthing problem with your start switch.

Are you talking about the flight director or the attitude indicator? They are two very different beasts.

Yeah, that's exactly it. The subscription is linked to a particular unit, so they need the new serial number.

No, I meant the magnetometer. Whether you have a separate one or whether you're using the internal one to the ADAHRS, you can recalibrate it in flight. It may be that you're calibration is just fine but it won't do it any harm to recalibrate and, who knows, it might be the magnetic heading that...

Have you tried recalibrating the magnetometer? It's an easy thing to try if you haven't already done so and may a lucky break.

Before you start disappearing down rabbit holes and looking up how the AoA works, check that your aircraft has the appropriate pitot/AoA tube. You won't get AoA if you just have a straight forward bit of pipe as a pitot tube. You'll need to have either the combined pitot/AoA tube, as sold by...

Of course it doesn't. The transponder's extended squitter is only used for the transmission of ADSB data. Whatever is used to receive ADSB is totally separate to the transponder.

Unless you specifically have an ADSB module, then ADSB is provided by sending GPS position from the HDX to the Mode S transponder's extended squitter. Therefore, as advised above, putting the transponder in standby prevents the transponder responding to interrogation AND from transmitting data...
