Default Flying the Skyview: the ILS-lite

Skyview 15 has added some nifty new features, but one in particular intrigued me. I call it ILS-lite.

With this version, you can select a particular runway to land on at your destination. If you do so, you can then configure the Skyview to provide vertical glideslope guidance to the autopilot. Note that this IS NOT a true ILS approach - it does not use and land-based navigation equipment. It is also NOT an approved method of making a real live instrument approach.

But it IS quite interesting.

From page 7-47 of the most recent users guide:

Quote:
When a specific runway is selected, a SkyView Flight
Plan can provide vertical navigation (VNAV) guidance
to the selected runway, including commanding the
AP to fly a specific glideslope. When the glideslope is
captured, the AP will fly the necessary vertical speed
to stay on the programmed glideslope. In this mode,
the glideslope vertical speed is indicated in the VSI. In
Figure 127, the blue tick mark shown in the VSI is the
calculated vertical speed to fly the glideslope and the
magenta line is the vertical speed necessary to arrive
at the selected runway threshold (or specified height
above).

To enable SkyView’s Flight Plan VNAV capability, prior
to flight go to SETUP MENU > MAP SETUP > VS REQ’D
OPTIONS and enter your desired VNAV parameters.
This is a short video of one of my early attempts to use it:

I still have a lot to learn about it, but it looks like it could come in handy someday.

And I apologize in advance for the low quality video.

My GRT EFIS has a similar feature, synthetic approach, that I use quite often when flying at night or to an unfamiliar airport in a congested area. It will couple to the AP, however I currently don't have one. It creates an approach highway in the sky at the standard glidepath, unless an ILS with a non-standard glidepath exists - in that case it emulates that approach.

It is a great tool to confirm you are lined up with the correct runway, correct airport (!), etc, and also helpful on those dark nights with limited visual cues.

Again, not to be used in IMC, but I think it's a great situational awareness tool.

GRT has had that feature since FOREVER! I've heard more than one story of it saving someone's butt in weather they got caught up in. For emergency or VFR-playtime use only... Obstacle clearance definitely not assured. It is handy when you're really lazy and don't want to kick the autopilot off until short final.

This feature is becoming fairly common in the modern EFIS systems. Garmin has something similar and so does AFS. It works great for doing a straight-in approach to any runway.

And, yes, it has been in the GRT systems forever, called the SAP.

Default MDA and Go-Around functions too!

Dave, you didn't mention the MDA and GA functions. I found the MDA bug on the bugs menu and enabled it. You can set the MDA with the left joystick/knob. Once set there will be orange digital readout of your set MDA and also an orange bug on the altitude tape.
Here is a screen shot, and in this case the plane has descended to minimums and there is a visual MDA warning on the screen as well as an aural "MINUMUMS" warning.

Also, if you have the pitch autopilot menu on the screen you will see the GO AROUND button. Push that GA button and the autopilot will immediately nose up at your default VS, switch to TRK, and there will be a warning to "ADD POWER" on the screen.

Of course, there are no approaches on the SkyView navigator, so you will have to set your own desired climb and track or heading on the go-around.

Lots to learn about this little computer

Have you been in touch with the folks at Dynon to see why it did not transition from VNAV to ALT per the autopilot annunciation?

Jesse, can you further explain the feature that Garmin has that is similar to this?
Cheers,
Tom.

I think Chelton was the first one to have that feature, and they used highway in the sky symbology.

Garmin has a vnav to a preselected altitude, so I don't know if they have added a runway selection option, but you can set the altitude you want to descend to and it will give you a vnav to it, then you use lnav to handle the lateral. It's not exactly the same, but can be made to act in a similar fashion.
