The Chicago Glider Club has an active membership of about 80 pilots involved in all aspects of the sport, from instruction through to participation in local, Regional and National soaring contests.
Founded in 1953, we own and manage all of our facilities: our grass runway, hangars and clubhouse were all constructed - and are now maintained - by dedicated and highly proficient members who take pride in the club.
We own a fleet of high quality sailplanes and towplanes that provide economical soaring to club members; many members also own their own sailplanes and base them at the CGC gliderport.
CLGC Soaring Weather and Data Analysis
Chicago Soaring Forecasts courtesy of CGC and NOAA-FSL
The following SkewT/LogP diagrams provide both actual and forecast soundings. The forecast soundings are derived from the actual soundings via computer simulations:
- TI's and SkewT/LogP diagrams: Locate the dry adiabat line for the daily forcast high (CGC is approximately 1000mb's MSL). The dry adiabat angles from lower right to upper left - colored blue, numbered in degrees F.
- Follow the dry adiabat up to the intersection with the sounding. The sounding is the squiggly line depicting temperature as a function of altitude - colored red. This intersection is the top of the thermal for today, given no complications, like clamp.
- At any altitude, the TI is the difference between the sounding temperature for that altitude and the dry adiabat temperature for that altitude.
- One rule of thumb is that a glider could expect to top out at TI=-3 (though many have experienced greater heights).

Forecast by NOAA's Forcast Systems Laboratory. This link provides 5 plots from the current time. I usually select the region around the drybulb from ground (~1000mb) to 10,000 feet (e.g., place cursor to right of drybulb/1000mb intersection, depress left mouse button, drag up and to the left to above 10,000 ft line). Expected cloudbases are indicated by the following: pressure (altitude), wetbulb temp, drybulb temp, and wind direction/speed.

CGC 500K Club
|The following members have made a cross-country soaring flight of at least 500 km from the Chicago Glider Club's normal field of operation:|
|The Boom-A-Rang contest is a task set in the shape of a boomerang. It starts at the club field and goes to TP1, back to the club field, then on to TP2, with a finish at the club field (hopefully). TP1 and TP2 are defined on the contest day in relation to the weather. This task is held in conjunction with the club's annual Pig Roast. Since this event is held in late September to early October, the task distance is usually rather short (35-50 miles). The following members have won the annual Boom-A-Rang contest. The speed listed is a handicap speed using the SSA Handicap list.|
The Chicago Glider Club was formed in 1953, as evidenced by this announcement that our local historian Simine Short found in the National Soaring Museum in 1998.
As described in the announcement (see text below the illustration), CGC was formed by a small group of members from the Chicagoland Glider Council, which had already been in existence since 1937.
A NEW CLUB IS BORN!
The Chicago Glider Club is not to be confused with the Chicagoland Glider Council. It is composed of members of the Council who wish to actively participate in the flying of gliders Those who are now activating the organization are as follows:
Mr. and Mrs. James Ducy Julian Hall Cyril Rogers Millard Wells Bob Mouroski Allen Schultz Joe Trefney George Ott Richard Hawker Sue Yager Pat Heraeg Bernie Mossberg
The Club has been formed around a Schweitzer TG3 owned by Bob Mouroski and Joe Trefney. The Chicagoland Glider Council and the Chicago Glider Club both wish to extend their gratitude to both of these men for making this ship available to them.
The purpose of this Club is to encourage the art of soaring flight in the Chicagoland area. The Council is most pleased with the interest and enthusiasm with which this new venture has been met. If this Club is as successful as it promises to be, other gliders will undoubtedly be made available under this plan for all those who wish to fly them.
Chicago Glider Club is located on Bell Road in Minooka, Illinois, about one mile north of US Highway 6. This is about 2 miles SE of Minooka, 9 miles E of Morris, and 8 miles SW of Joliet (about 2 miles SW of the intersection of I-55 and I-80). From Bell Road, turn East onto Airport Road; this road runs immediately along side the grass runway, so please drive with caution and look out for gliders and tow planes.
The clubhouse phone is 815-467-9861.
Use the interactive Google map below to see our location.
The club owns its own grass runway, two large hangers, a clubhouse, and a large grass area for trailer tie-down and sailplane assembly. The clubhouse has a large general area, two rest rooms with showers, and a kitchen.
Construction of the runway, clubhouse, and hangers was accomplished by volunteer workers from the membership. The only professional help used was to pour the concrete for the large hanger and clubhouse floors.
|The runway is a grass strip about 300 feet wide and about 1800 feet long with an east-west orientation. On the north side of the property near the east end is the fully equipped clubhouse and 2 hangers.|
|Adjacent to the east side of the hangers is a large grass area used for trailer tie-down and sailplane assembly.|
|The inside of the clubhouse has a large general area, two restrooms with showers, and a fully equipped kitchen.|
