KATL Atlanta Hartsfield-Jackson — Instrument Checkride Guide

What kind of airport is KATL for IFR operations?

KATL is a major Class B hub airport operating under continuous 24-hour tower and TRACON control. As the world's busiest airport by passenger count — serving over 108 million passengers in 2024 according to Hartsfield-Jackson airport authority statistics — Atlanta handles roughly 805,000 aircraft operations per year. That traffic density shapes every aspect of IFR operations at and near KATL: expect sequencing, speed control, and holding to be routine parts of any arrival, and expect no tolerance for procedural delays or frequency confusion.

Atlanta is the primary hub for Delta Air Lines and a major connecting bank for the entire southeastern United States. The FAA Chart Supplement (via AirNav) lists KATL as a Landing Rights Airport with 24-hour operations. All approaches require ATC coordination through Atlanta TRACON, and a critical restriction applies: practice instrument approaches are not permitted on any runway at KATL.

What instrument approaches are published at KATL?

KATL offers one of the most comprehensive published instrument approach libraries in the United States, with approaches available to all 10 runway ends across 5 runways.

Per AirNav's KATL data, the ILS PRM procedures on runways 09R, 10, 27L, and 28 support simultaneous close-parallel operations using Precision Runway Monitor technology. Pilots flying PRM approaches must receive a PRM approach briefing and monitor a dedicated PRM frequency alongside the tower frequency. The RNAV (RNP) Z procedures require specific RNP authorization — verify aircraft and crew eligibility before briefing these approaches for a checkride.

What is the runway configuration at KATL?

KATL has 5 parallel concrete runways, all aligned approximately east-west on a 095°/275° magnetic heading.

All surfaces are grooved concrete. Per the FAA Chart Supplement data published on AirNav, the preferential runway use program directs that runways 08R/26L and 09L/27R are primarily used for departures, while 08L/26R and 09R/27L handle the bulk of arrivals. Runway 10/28 is used during high-demand periods and specialized operations. Elevation is 1,026 feet MSL.

KATL uses an ASDE-X surface detection system. All operations require a functioning transponder with altitude encoding and ADS-B Out, consistent with 14 CFR 91.225.

What are the common weather patterns at KATL?

Atlanta's weather creates two distinct IFR threat environments depending on the season.

Summer (May–September): Afternoon convective activity dominates. Surface heating drives convective development most afternoons, with thunderstorms common between 14:00 and 21:00 local time. These storms frequently trigger FAA Ground Delay Programs (GDPs) and miles-in-trail restrictions. Pilots arriving or departing during this window should expect extended routing, holding, and possible en-route diversions. SIGMET awareness and convective SIGMET interpretation are essential.

Winter (November–February): Freezing rain and ice are the primary hazards — Atlanta is in a geographic transition zone where warm Gulf air overrides cold continental air masses, producing significant icing events. Snowfall is infrequent but can shut down operations rapidly when it occurs, as the region has limited deicing infrastructure compared to northern hubs. Low IFR conditions with ceilings below 500 feet and visibility under 1 mile are possible during these events.

Year-round: Early morning radiation fog is common during fall and spring, often clearing by mid-morning. Dew point spreads are frequently tight overnight, supporting fog formation. Pilots should brief the ATIS for fog advisories on arrival at or before 06:00 local.

What should you expect on an instrument checkride at KATL?

An instrument rating checkride at KATL is not a typical general aviation experience — and a DPE conducting a practical test here will expect you to handle the environment like the professional instrument pilot you're about to become certified as.

Traffic density and sequencing. KATL and its surrounding airspace handle hundreds of arrivals and departures per hour. Atlanta TRACON will sequence you behind jet traffic, issue speed restrictions (commonly 180 knots to the FAF, then 160 to the marker), and expect prompt, accurate readbacks. The DPE will be observing how you manage ATC communications while maintaining precise instrument flying — multitasking under realistic workload is the core competency being evaluated.

Ground delay and flow control scenarios. If a convective event is underway, you may receive a departure delay or an en-route hold assignment as part of a realistic checkride scenario. How you brief and fly a published holding pattern, including entry selection and timing, is evaluated under ACS Task IR.III.A. A DPE at KATL may use actual traffic conditions as checkride material — "we've been assigned holding at the COLLA intersection, demonstrate the entry and brief me on our fuel state."

No practice approaches. The FAA Chart Supplement for KATL explicitly prohibits practice instrument approaches, touch-and-go operations, and low approaches on all runways. Every approach flown during a checkride here is a real approach coordinated with ATC. This means you brief it correctly, fly it to published minimums, and execute the missed approach or landing with full procedural compliance. Under 14 CFR 91.175, you must not descend below DA/MDA without the required visual references — at KATL, ATC will expect you to go missed if you can't land.

Frequencies and cockpit management. KATL uses runway-specific tower and ground frequencies, a dedicated D-ATIS with separate arrival (119.65) and departure (125.55) channels, and multiple approach/departure frequencies depending on your runway assignment. Pre-loading the correct frequency sequence and briefing the approach plate — including the correct tower frequency for your specific runway — before the IAF is expected. Fumbling for frequencies inside the FAF is a common error that signals poor cockpit organization.

Class B airspace awareness. From the moment you enter the Mode C veil (30 nm radius) and certainly once you contact Atlanta Approach, you are operating in one of the busiest terminal environments in the world. Know your clearance limits, maintain your assigned altitude until cleared to descend, and do not deviate from ATC instructions without explicitly requesting it. The DPE may test your knowledge of Class B operating requirements and ADS-B mandate under 14 CFR 91.225.

Frequently Asked Questions

Q: What airspace class is KATL?

KATL Atlanta Hartsfield-Jackson operates within Class B airspace. Instrument arrivals and departures are handled by Atlanta Approach/Departure on assigned frequencies before contacting tower on one of the runway-specific tower frequencies.

Q: Are practice instrument approaches permitted at KATL?

No. The FAA Chart Supplement explicitly states: "ALL RWYS, TOUCH AND GO OPERATIONS, LOW APPROACHES, AND PRACTICE INSTRUMENT APPROACHES NOT PERMITTED." Instrument checkride flight tests at KATL require actual IFR operations with ATC coordination — not practice approaches.

Q: What ILS approaches are published at KATL?

KATL has ILS or LOC approaches published to all five runways — 08L, 08R, 09L, 09R, 10, 26L, 26R, 27L, 27R, and 28. Select runways also have ILS PRM (Precision Runway Monitor) procedures for simultaneous close-parallel operations.

Q: What is the elevation of KATL?

Hartsfield-Jackson Atlanta International Airport sits at 1,026 feet MSL (surveyed), which affects density altitude calculations during summer operations when temperatures routinely exceed 90°F.

Q: Which KATL runways are used for arrivals versus departures?

Per the FAA Chart Supplement preferential runway program, runways 08R/26L and 09L/27R are primarily used for departures; runways 08L/26R and 09R/27L are primarily used for arrivals. Runway 10/28 provides additional capacity during high-traffic periods.

Q: What Category II/III approaches are available at KATL?

CAT II and CAT III ILS approaches are published for select runways at KATL. This capability supports low-visibility operations and is one reason KATL can maintain schedule integrity during winter fog and low-ceiling weather events.

Q: How does Atlanta summer convective weather affect IFR operations at KATL?

Afternoon thunderstorms during summer months routinely cause ground delay programs and miles-in-trail restrictions at KATL. Flights may be held at the departure airport or placed in extended terminal holds while Atlanta TRACON sequences arrivals around convective cells.

Q: Does KATL require ADS-B for operations?

Yes. KATL uses an ASDE-X surface detection system and requires transponder altitude reporting and ADS-B Out capability for all operations in the Class B airspace, consistent with 14 CFR 91.225 and 14 CFR 91.227.
