    Sheared screw and auto-trim interaction.

    This is a lessons learned. I had a shear screw fail in my roll servo.  The underlying cause was the castellated nut was not properly torqued, so the screw was taking all of the load.  This was a replacement (rebuilt) servo from Dynon received as a swap for a non-Skyview compatible unit. Even...

    Dual Frequency ADS-B Receiver

    I think that there is a bit more to this. Let's say that you have an ADS-B receiver with UAT-in only. As long as you are near an ADS-B groundstation, and above the minimum altitude, you have traffic. As you said, if you drop too low, you will lose traffic. If, however, you also have 1090ES...

    autopilot -- stick shaker?

    There is likely to be a definitive answer on the *best* way to indicate AoA and stall warnings coming from the FAA in the near future. We (a company I am involved in) have sold the FAA several primary control devices that can emulate airframe forces and haptic feedback. Their intent is to do a...

    Auto pilot pulsing

    This is speculation, but I have zero hunting on my Harmon Rocket, so let's look at the differences between, say an RV-9a and an HR-II. I have built and flown both. I found the RV-9A to be very sensitive to trim and very light in pitch control for small pitch excursions. The HR-II, despite...

    Auto pilot pulsing

    Casting my memory to my Control Systems courses from decades ago, what you are seeing is the characteristic of what is called a bang-bang controller. It is characteristic of a system that has too much free play/hysteresis. One way to check is to turn off auto-trim during cruise flight...

    Erratic RPM

    If you've had reliable rpm indications that are changing suddenly, the first thing to check is your ignition systems. Fouled plugs, improper gaps or worn points in the mag can lead to problems with the indicated rpm derived from p-lead resistors. The IO-540 is 50% more susceptible to this...

    Checklists

    A suggestion for how the checklists are displayed on the SkyView screens: Highlight the checklist line and use the scroll wheel to move up and down. This makes it easier to keep your place in the list. Vern

    AoA linked to flap setting

    I'm not sure that this is necessary.  Stalling indicated AoA does not depend on flap position, although stalling pitch and airspeed do. Airspeed indicators show the difference between clean and flaps extended stalling speed, which leads to the conclusion that stalling iAoA must also change, but...

    Checklists

    You are not supposed to save the file in a new format, just keep it as xlsx or xls.  What you do is select the checklist text and copy it (ctrl-c) or right click copy.  Then you create or open a plain text file on your computer and paste-special or past-as unformatted or plain text. You can do...

    Checklists

    Re: Checklist spreadsheet suggestion For your checklist tool: It would be nice to have a character count per line displayed so that we can manage line length. Alternatively, truncate the text output to show exactly how it will be displayed on screen. Right now, I just do it with an external...

    SkyView Checklists Editor

    One Minor Bug on Checklist 16 "EMERCENCY:  FIRE ELECTRICAL".  Emergency is spelled wrong. I've tried all the checklists and will upload tomorrow if I have time.  Thanks for the great tool.  I never thought I would use on-screen checklists, but it works well for startup.  Replacing the SkyView...

    Suggestions for after boot infoscreen

    Why not just put up the pre-start checklist? This way, we can do something useful while waiting for bootup.

    Excel Checklist Editor Utility

    I have put together an Excel checklist editor to simplify the management of checklists and convert them to the SkyView .txt format.  All of my paper checklists are already in Excel, so this is easy for me. This is not a work of art, and I expect folks to improve it.  Unfortunately, this Forum...

    Larger fonts on 7 inch display

    I have a 10 and a 7" screen on my SV panel.  The 7 inch display is simply a scaled view of the 10 inch screen.  This makes much of the text illegible unless your nose is near the screen.  My ipad mini between my knees is more legible for map reading. If you want to encourage Dynon to fix this...

    AOA indicator

    It's the only avionics product that I have ever discontinued. It's dead and buried .  I don't think it enhanced safety and that's the big reason.  Audio and haptics is the way to go.  I talked to ASTM and FAA reps about stall avoidance and it's more complicated than a visual display mounted to...
