KPWK Chicago Executive — Instrument Checkride Guide

What kind of airport is KPWK and what is its IFR environment?

Chicago Executive Airport (KPWK) is located in Wheeling, Illinois, 18 miles north of downtown Chicago, at 647 ft MSL. It operates continuously under a Class D surface area while within the broader Chicago O'Hare Class B structure. Tower operates 24 hours on 119.9 MHz; ATIS is continuous on 124.2 MHz. Ground is 121.7 MHz; Clearance Delivery is 124.7 MHz.

KPWK is one of the busiest general aviation airports in Illinois. Chicago Approach handles arrivals and departures on 120.55 and 128.575 MHz. Because the airport sits inside the O'Hare Class B area, IFR departures typically require Class B penetration — under 14 CFR 91.131, that clearance must be explicit. On an IFR clearance, ATC provides it as part of the departure sequence.

What instrument approaches are published at KPWK?

KPWK publishes three instrument approach procedures, sourced from SkyVector.

No instrument approaches are published for Runways 06, 12, 24, or 34. In IFR conditions, operations are effectively limited to Runways 16 and 30. Always verify current minima on official FAA charts — 14 CFR 91.175 governs descent and visibility requirements.

What is the runway configuration at KPWK?

KPWK has three runways of varying lengths. Only two runway ends have published approaches.

Runway 16/34 is the primary IFR runway. At 5,001 ft, it accommodates most GA aircraft with room for a standard landing rollout. The shorter Runway 06/24 has no approach procedure and is generally used in clear weather for noise abatement or light aircraft operations. Active runway configuration depends on wind — the DPE will expect you to monitor ATIS and confirm runway assignment before descent.

How does Chicago Class B airspace affect IFR operations at KPWK?

KPWK sits within the Chicago O'Hare Class B area. Every IFR departure from KPWK that climbs above the Class D ceiling enters Class B airspace — the Class D ceiling at KPWK is well below the Class B floor on at least one sector. Under 14 CFR 91.131, an explicit ATC clearance is required to operate in Class B airspace. On a filed IFR clearance, Chicago Departure provides that authorization as part of normal sequencing.

The practical implication for a checkride: as soon as you depart KPWK on an IFR clearance, you are in one of the most complex ATC environments in the Midwest. Expect departure headings and altitudes that route you clear of O'Hare traffic flows. Clearance readback must be exact — Chicago controllers do not tolerate ambiguous readbacks near Class B. The DPE will evaluate communication discipline from the first radio call.

What weather patterns affect KPWK?

Lake effect weather is the most significant and unique IFR hazard at KPWK. Cold northwest winds crossing the warmer waters of Lake Michigan — located roughly 8 miles to the east — produce sudden bands of heavy snow, low ceilings, and near-zero visibility that can develop in minutes during the October–February season. Lake effect bands are narrow but intense and highly localized; KPWK may be in IMC while Midway (KMDW), just 20 miles south, is VFR.

Summer convective activity is also common. Midwest squall lines can move through Chicago at 40–50 knots, dropping ceilings rapidly ahead of the line. Pilots departing in the evening should review convective SIGMETs from aviationweather.gov and have a divert plan ready.

Winter icing exists at all levels during frontal passages. The inversion common to lake effect conditions can put supercooled large droplet (SLD) icing at approach altitudes without a clear PIREP trail.

What should you expect on an instrument checkride at KPWK?

A checkride at Chicago Executive is primarily an exercise in Class B airspace management and communication precision. From the first call to Clearance Delivery on 124.7 MHz through the final approach briefing, the DPE is evaluating whether you operate competently in a complex ATC environment — not just whether you can fly an ILS.

Expect a full departure clearance with an initial altitude that is below your cruise altitude — a standard O'Hare complex feature. The DPE may assign a specific departure heading and ask you to maintain situational awareness of the Class B boundaries while climbing. If you level off at the wrong altitude or miss a heading, ATC will issue a correction and the DPE will note it.

The ILS RWY 16 is the expected primary approach. At 5,001 ft of runway with precision guidance, it is a clean evaluative environment for tracking discipline and callout procedures under 14 CFR 91.175. After the approach, the DPE will likely request the RNAV RWY 30 — requiring you to brief a second approach while tracking radar vectors, a realistic multitasking scenario.

Missed approach at KPWK puts you immediately back into the Class B structure. Declaring a missed approach on frequency and following ATC vectors without deviating from the missed approach path is a core competency that the DPE will observe closely.

Practice Questions

1. You receive a departure clearance from KPWK that includes "climb and maintain 3,000, expect 8,000 ten minutes after departure." The O'Hare Class B floor in your direction of flight is at 2,500 ft. What clearance authority do you have to climb through 2,500 ft?

2. On the ILS RWY 16 at KPWK, you intercept the glideslope from below at 2,800 ft and note the CDI shows a full-scale fly-right deflection. What are your immediate actions and what ACS standards apply?

3. After a missed approach on the LOC RWY 16, Chicago Approach issues a vector and altitude that conflict with the published missed approach procedure. Which takes precedence and why?

4. The TAF for KPWK shows OVC003 with a lake effect snow band. The RNAV (GPS) RWY 16 publishes LNAV MDA at 1,000 ft and visibility ¾ sm. Is this approach legal in the forecast conditions? What visibility minimum applies to your aircraft under 14 CFR 91.175?

5. You are arriving KPWK on an IFR clearance and Chicago Approach hands you off to KPWK Tower at 4 miles on the ILS. The tower clears you to land. What other reports or calls are still expected of you before touchdown?

Frequently Asked Questions

Q: What instrument approaches are published at KPWK?

KPWK publishes three instrument approach procedures: ILS or LOC to Runway 16, RNAV (GPS) to Runway 16, and RNAV (GPS) to Runway 30. The ILS RWY 16 is the sole precision approach. No approaches are published for Runways 06, 12, 24, or 34.

Q: What airspace class is KPWK in?

Chicago Executive Airport operates within the Chicago Class B airspace shelf. The airport itself has a Class D surface area while the tower is active. Under 14 CFR 91.131, an explicit ATC clearance is required before entering Class B airspace, which surrounds KPWK on multiple sides.

Q: What is the ATIS frequency at KPWK?

KPWK ATIS broadcasts on 124.2 MHz. Tower frequency is 119.9 MHz; Ground is 121.7 MHz; Clearance Delivery is 124.7 MHz. Chicago Approach serves KPWK on 120.55 and 128.575 MHz.

Q: What are the runway lengths at KPWK?

KPWK has three runways: Runway 16/34 at 5,001 × 150 feet (the primary IFR runway), Runway 12/30 at 4,415 × 75 feet, and Runway 06/24 at 3,677 × 50 feet. Only Runway 16 and Runway 30 have published instrument approaches.

Q: Does KPWK have continuous tower operations?

Yes. Chicago Executive Airport tower operates continuously (24 hours). ATIS is also continuous on 124.2 MHz. The airport is one of the busiest general aviation airports in the Chicago metropolitan area.

Q: What weather hazards affect KPWK?

Lake effect weather from Lake Michigan is the primary IFR hazard at KPWK. Cold northwest winds crossing the warm lake produce persistent low ceilings, snow showers, and reduced visibility primarily from October through February. Summer convective activity and winter icing at all levels are also significant.

Q: How close is KPWK to Chicago Class B airspace?

Chicago Executive Airport sits within the Chicago O'Hare (KORD) Class B footprint. IFR departures from KPWK routinely require Class B clearances from Chicago Departure. Pilots must understand Class B clearance procedures under 14 CFR 91.131 and be prepared to receive complex routing instructions immediately after departure.
