[BC] Your site in view - Radio Town USA Chicago

[Paul Smith W4KNX]

I just looked at the Runway 32R ILS approach chart for ORD (O'Hare) in
Chicago.  These two towers do not interfere with the approaches to this
runway or runway 22.  The towers appear to be due east of OHare.  The only
thing I see those towers doing is making the MSA (minimum safe altitude)
higher in the Southeast quadrant within a 25 mile radius of the airport.
Sarasota here has a similar situation with a 1700 foot tower causing an
increase in the MSA but does not cause any problems with any approach.

Both of the aux. WGN and WBBM towers are painted.  Both sites are
within/under the approach cone for O'Hare runways 9L and 9R.  They both
pre-date O'Hare by 30 years...  Under no conditions would those towers
be built today...local zoning not withstanding.
