KYIP Charts have minor errors

Hi. I am a new subscriber so bear with me if this is the wrong place/way to report this issue.

After subscribing, I naturally went to my local airport from which I start most of my flights. I noticed a couple errors in the chart, but I also discovered several changes in the airport that I was not aware of. (Thank you!)

KYIP Willow Run airport is located in Ypsilanti, MI, just east of KDTW - Detroit Metro airport.
The chart has the following errors.

  1. There is an unmarked taxiway shown on the chart running parallel to runway 23L from the midpoint to the SW end. This pavement no longer exists IRL. (This used to be the continuation of taxiway A)

  2. There is also a missing continuation of taxiway H at the west end that leads to the west parking area as shown in the satellite imagery. The chart only depicts the alternate taxiway D off of H leading to the west parking area.

What I learned is that runway 27 has been shortened up by almost a third on the east end, no longer crosses runway 23L, and the short taxiway to the old runway 27 start has been removed. Also, runway 23R has been de-commissioned. Almost all of my flights have always started from either runway 27 or 23L, depending on the aircraft and the weather. I would never have known these changes had occurred without this Navigraph subscription.

This really highlights the need for accurate, up to date charts! Thanks again.

Hi,

I don’t see any of the issues you mention on the current Jeppesen airport diagram for KYIP (dated 24 NOV 2023). Our airport diagram precisely matches the current FAA charts for all above points.

Also, you mention runways 23L and 23R, but we don’t have these at all in our charts, only 23.

Can you please attach a screenshot to illustrate what you mean is wrong?
