    SV-KNOB-DIMMER Questions

    Only here - you meant to say "zero volts" at the bottom (being ground, and all), not 12V at the bottom (in which case absolutely nothing would happen on any of the circuits :-).

    lidar based altimeter

    So I use this: https://lightwarelidar.com/products/sf11-c-100-m in an automatic landing gear extension circuit on my COZY MKIV. It's part of a circuit that will lower the LG if I'm >40 KIAS, <90 KIAS, <10% throttle, and <400 ft. AGL. I'm using it as a switch, but it does have an analog voltage...

    AP panel but only for trim?

    I do trust that I can override them, and the torque limit of the servos is set so that can be accomplished while never slipping during normal use (and I can always break the shear screw, if it comes to that). But the last thing anyone needs, as you found out, is to have someone/something...

    SV AP panel mount install

    Ahem. If you review the Lancair ES General Wiring Document: https://documents.lancair.com/aircraft_documents/ES-ESP/General_Wiring.pdf you can see that the airplane uses "MAC" servos - now "Ray Allen". The fact that the document recommends 5A fuses/CB's to protect the WIRING to the servos is...

    SV AP panel mount install

    Well, have you read the specifications for the TrimAmp on page 23-17 of the install manual? The maximum motor supply is 3A (not really sure what the point of the thing is, if all it does is increase the maximum motor current from 2A to 3A - that's hardly a large increase). The total current...

    SV AP panel mount install

    Some terminology here - I think by "servos" you're referring to the trim motors, which are almost always just 12V DC motors - not "servos". I also think you're conflating two functions here - first, the "Auto-Trim", which merely trims out the force on the A/P servo, _IF_ you enable the...

    AP panel but only for trim?

    I've never had the A/P go nuts on me (ever, in about 15 years or so between the D10A and the Skyview HDX), but still - it only needs to happen once, and you're always hand flying the takeoffs and landings anyway.

    AP panel but only for trim?

    Sure. I have a power switch for my servos (I turn them off for takeoff and landing), so they're not on, powered, or talking on the bus. The trim system through the A/P controller panel works fine.

    Climbing using IAS

    Interesting again. I wonder why that would be. I know that in tractor airplanes, thrust is destabilizing and in pushers (aft pushers, not on top) thrust is stabilizing, but I have no idea whether that holds true for airplanes with jets on the wings. In any case, I've got a COZY MKIV canard, so I...

    Climbing using IAS

    Interesting. I've been performing some glide tests recently and using IAS mode for both climb and descent. On a calm day, the IAS mode will hold +/- 3KIAS in the climb, and within +/- 1 KIAS in descent. This in a COZY MKIV. In turbulence, pitch control (IAS, VS, Altitude) sucks, though - the...

    Alternator Failure — What’s left?

    Yes. The GPS2020 antenna is powered from the EFIS, not separately, per page 8-7 of the installation manual.

    MDA Bug selection

    I have exactly the same behavior, and it's just as annoying for me as it is for you :-). Says it's on in the menu, but isn't until you go to the menu and then come back out of the menu.

    D10A GPS position output in NMEA format

    Interesting that that unit is not mentioned in the experimental version of the D10A installation guide anywhere. And it is both the antenna AND the receiver. They must have come out with that when the started using the D10As in TC'd aircraft. In any case, the Serial output data shown in the...

    D10A GPS position output in NMEA format

    Since the D10A does not have an internal GPS receiver (or antenna) and only receives GPS information from an EXTERNAL GPS system (panel mount or portable), I'm not sure what you're asking here. The D10A cannot provide a GPS signal to anything, as it has no GPS functionality internally. What...

    VNAV

    Agreed. Actually, @Dynon101 said nothing about IFR approaches, and @-Bob explicitly said "VFR Approach". You can infer what you like, but no one mentioned inventing IFR approaches, and there are a zillion VFR approaches in the Garmin Navigator database. Maybe even one to the airport that @-Bob...

    VNAV

    Well, almost. Per the User Guide, Rev J, pages 5-56 and 5-57, the approach angle, the distance at the airport and the altitude at the airport descent point are all configurable - it's not confined to pattern altitude or 2 degrees. So if one has a home airport and would like to setup the...

    Math and Conditional (Boolean) Calculations for display parameters?

    Boy, if there is some way to do this, that would be great, but I don't think so. I've been using Dynon equipment since 2007 and have never seen this capability in any of the monitoring equipment. If nothing else, some built in smarts, such as: Don't alarm on low oil pressure if RPM is zero...

    Seattle Avionics vs Garmin GPS175 published appoaches

    Since the title of this thread is "Seattle Avionics vs Garmin GPS175 published approaches", I was only addressing GPS approaches, since that's all the 175 can do. You are obviously correct that you don't need an approved GPS Navigator to do VOR, LOC, or ILS approaches. I don't know how...

    Seattle Avionics vs Garmin GPS175 published appoaches

    Garmin uses an SD card (or microSD card in an SD card adapter). You update it on your computer using proprietary Garmin software (free) from the Garmin website and the unit will sense if the databases need to be updated on bootup with the card installed. It will yell at you if the databases are...

    Seattle Avionics vs Garmin GPS175 published appoaches

    I answered your questions, Charlie. See posts #2 and #4. You may not like the answers, but what questions do you think weren't answered either by me or the other folks that reiterated the same response?
