Chicago Midway International Airport, IL (KMDW)

Airports

Chicago Midway International Airport started life in 1923 on 30 acres as Chicago Air Park, complete with one runway set up for the air mail. Over the years the airport has grown a little in area, it now occupies one square mile (640 acres), but a lot in business. KMDW was the 30th busiest in the country for the year 2005.

The problem with Midway is that it sits in the middle of the city, there are busy roads on each side of the square airport. Sure it has eight usable runways, but four of those shrink to less than 5,000 feet of landing pavement. An undershoot or overshoot will likely make you a customer at a McDonald's or a Giordano's if you prefer deep dish pizza

Arrival Notes

The airport sits in the middle of the city and there are major roads at the end of each runway.

Runway 04L

Runway 04L is straight forward. The following is from an ILS 04R with a side step to 04L: KMDW Runway 04R Sidestep 04L.

Figure: KMDW ILS 31C, circle 22L, from Eddie's notes.

The old school solution for the Runways 22 was to fly the ILS 31C circle to 22L or 22R. You will be tempted to fly directly north, aligned with the streets but this doesn't work because that angles you into the runway about 30 degrees. Another failed technique is to turn to the train station technique doesn't work, but that doesn't allow for Category C turn radius. A better technique is to stick with basic circle procedure:

  1. Fly the ILS until 1.7 nm (Cat C) from the runway. No, turn sooner! They are expecting a turn at 2.3 nm from the Category D airplanes so why not?
  2. Turn right to a reciprocal heading to the landing runway, 040°, downwind.
  3. As the landing runway appears 45° behind you, turn base toward the train station.
  4. Turn final to roll out on course.

Note: It really isn't a train station, but it looks like one.

During a circling approach, a Category C aircraft cannot exceed 140 knots. You will be close to that in a G-450. The ILS 31 Circle to Runway 22 is often used with very strong tailwinds on Runway 31, which means you will need to adjust your downwind 040° heading or even your offset.

The new school method is to fly either the RNAV(GPS) 22L or RNAV(RNP) 22L, which brings you in at an eleven degree angle. (That's close enough under TERPS to call it a straight-in, but it will require some last minute maneuvering. If you are flying a high tech aircraft they will often assign the "RNAV Yankee" approach, which is an RNP AR approach. If you are not RNAV(RNP) qualified you will have to ask for the "RNAV Zulu" approach instead, which is the RNAV(GPS) approach.

If you cannot fly either, you will have to decline the approach. They will send you to a holding pattern until they can fit you into the ILS 31C, circle to 22L or 22R.

Runway 31C

The preferred approach is the ILS to 31C, it is easy except you are making an approach over the city which goes right up to the end of the runway. Many radios can misinterpret the Morse code identifier and IMXT may show up as IMDT.

Departure Notes

The only two departure procedures (Cicero and Midway) are straight forward, requiring quick turns and restricting speed to 250 Knots until advised.
