How to fly a DME ARC for Indianapolis Executive (KTYQ) VOR Rwy 18

How to fly a DME ARC for Indianapolis Executive (KTYQ) VOR Rwy 18. Before we get started, I must point out, the VOR RWY 18 non-precision instrument approach does NOT have a DME ARC. I created a fake 20 DME ARC for this video, with the intention to join the KTYQ VOR RWY 18 Initial Approach Fix (IAF).

If were wondering why I added a fake DME arc to this approach, one of my fellow colleagues was having difficulty visualizing flying DME arcs. This is why I added a DME arc to one of the local Indianapolis non-precision approaches. I wanted to use a local approach, but I have not yet found a local approach with a DME arc. I am guessing DME arcs are becoming a rare item with GPS approaches starting to dominate the landscape, which is good to see.

The actual approach plate used to create the video is displayed during the entire video. If you are unable to read the approach plate on the video, you can download the PDF by clicking here or on the image. It might be a little difficult to view the video on a mobile device and see all of the details, so I would recommend watching on a larger screen.

This video was created with flight simulator X-Plane 11.  The intention of this video is to help the viewer visualize the approach on the HSI, by using the CDI needle and the VOR bearing needle at the same time. Also to show how a DME ARC is flown, with an initial 90 degree turn, followed by incremental turns to stay along the desired DME arc. (Although, I could have flown the 20 DME ARC a bit better initially.)

How to visualize using the HSI. Think of the entire HSI as a plan view, looking down on the instrument approach you are going to fly. In this case, the center of the HSI represents the VOR. The CDI represents the inbound track as portrayed on the published approach plate. The VOR bearing needle (tail of the needle) represents the position of the aircraft in relation to the inbound or outbound approach leg as it flies around the fake 20 DME arc. As the tail of the VOR bearing needle approaches within 10 degrees of the desired inbound or outbound track for the approach, the CDI needle will start moving. Remember the CDI full scale deflection for a VOR is 10 degrees.

KTYQ on a VFR Sectional. Located North of Indianapolis International Airport (KIND). Note obstacles located to the Northeast.

For this video, I have added titles on the artificial horizon during the video, briefly explaining what is happening in the video. The titles are hard to miss. Since relocating to Indianapolis, I did not bring a good quality microphone with me, resulting in no voice over commentary for this video. A microphone has since been ordered and voice overs will make videos easier to discuss in the future.
