How long is the ATP checkride?

Plan for a full day. The oral typically runs 2–4 hours for an ATP-only test, and longer — often 4–6 hours total — when combined with an initial type rating. The practical portion in a Level C/D simulator usually takes 3–4 hours including briefings and debrief. If your ride is split across two days (oral day, sim day), confirm the schedule with your check airman or DPE. Show up rested; ATP rides are mentally taxing and examiners notice fatigue-induced errors.

What's on the ATP oral exam?

The oral covers everything in FAR 61.155: high-altitude aerodynamics, turbojet performance, engine-out procedures, icing, weather (including microbursts and wind shear), regulations, aircraft systems, MEL/CDL use, and CRM/threat-and-error management. Expect scenario-based questioning rather than rote recall. If you're testing in a transport airplane, every system on that aircraft is fair game, plus operational items like dispatch release, alternate selection, and Part 117 fatigue rules if you're going Part 121.

Do I need ATP-CTP before the checkride?

Yes, if you're going for an ATP-Multiengine certificate. FAR 61.156 requires completion of an Airline Transport Pilot Certification Training Program — 30 hours of academic ground plus 10 hours in a Level C or higher full flight simulator — before you can even take the ATP knowledge test, let alone the practical. ATP-CTP is not required for the ATP-Single Engine certificate, but most pilots taking that path are already past it from a prior airline indoc.

What are the ATP ACS tolerances?

Tighter than commercial. On instrument tasks: altitude ±100 feet, heading ±10°, airspeed +10/−5 knots. Steep turns require a 45° bank held within ±5°, altitude ±100 feet, and airspeed ±10 knots. Precision approaches: no more than one-dot deflection of localizer or glideslope. Holding airspeed and timing must meet AIM standards. The ATP ACS (FAA-S-ACS-11) lists the exact tolerance for each task — review them before your sim profile.

Can I take the ATP checkride in a simulator?

Yes. FAR 61.158 and the ATP ACS authorize the practical test in a qualified Level C or Level D full flight simulator, which is how nearly all ATP-Multiengine rides combined with type ratings are conducted at airline training centers. The Restricted ATP and ATP-Single Engine can be flown in an actual airplane. Whichever path, every maneuver in the ACS must be demonstrated to ATP tolerances.

How many hours do I need for an unrestricted ATP?

1,500 hours total time per FAR 61.159, including 500 cross-country, 100 night, 75 instrument, 50 multiengine, and 250 hours pilot-in-command (with sub-requirements for cross-country and night PIC). Restricted ATP under FAR 61.160 lowers total time to 750 hours for qualifying military pilots, 1,000 for graduates of an approved Bachelor's aviation program, or 1,250 for an approved Associate's program — but R-ATP holders can only act as SIC at Part 121 carriers until they reach 1,500.

What's the hardest part of the ATP checkride?

Most pilots cite single-engine instrument approaches and engine failures at V1 as the toughest practical items — they require precise rudder, accurate trim, and disciplined CRM all at once. On the oral, high-altitude aerodynamics and engine-out performance (second-segment climb, driftdown, balanced field) trip up pilots who memorized rather than understood. The fix is scenario practice: not "what is V2?" but "you lose number two at V1 — walk me through it."

How do I prepare for the ATP oral exam?

Three steps. First, study the ATP ACS cover to cover so you know exactly what's testable. Second, master the regulatory base: FAR 61.153, 61.155, 61.156, 61.158, 61.159, and Part 117 if you're 121-bound. Third, drill scenario-based questions out loud — saying answers in your head is not preparation. Use a study partner, an instructor, or an AI examiner that pushes back when your answer is shallow. Aim for 2–3 full mock orals before the real one.

ATP Checkride Prep: Oral & Practical Guide

The ATP checkride is the most demanding practical test in civilian aviation. The bar is higher, the tolerances are tighter, and the oral exam assumes you already think like a captain. This page is built for pilots who are taking the ATP practical test in either an airplane (single- or multi-engine) or as part of an Airline Transport Pilot Certification Training Program (ATP-CTP) leading into a type rating in a transport-category aircraft.

If you're prepping for an ATP-Multiengine ride bundled with an initial type rating in a 737, A320, ERJ, or CRJ, almost everything below applies — the practical test is conducted under the Airline Transport Pilot ACS (FAA-S-ACS-11) with the type-rating tasks layered on top.

ATP Eligibility: What FAR 61.153 Actually Requires

Before you ever schedule a checkride, you must satisfy FAR 61.153. The headline requirements:

Be at least 23 years old (21 for Restricted ATP under FAR 61.160)
Be able to read, speak, write, and understand English
Be of good moral character
Hold a Commercial Pilot Certificate (or foreign ATP) with an instrument rating
Have completed the ATP-CTP ground course (FAR 61.156) before taking the ATP knowledge test
Pass the ATP knowledge test (ATA/ATM)
Meet the aeronautical experience of FAR 61.159 (airplane) or 61.161 (helicopter)
Pass the practical test under the ATP ACS

For the airplane category, FAR 61.155 lays out the aeronautical knowledge areas the test covers — everything from high-altitude aerodynamics and turbojet performance to crew resource management, MEL/CDL philosophy, and 14 CFR Part 117 flight and duty rules for those going Part 121.

ATP-CTP: The Prerequisite You Can't Skip

FAR 61.156 requires every applicant for an ATP-Multiengine certificate to complete an Airline Transport Pilot Certification Training Program before taking the ATP knowledge test. CTP includes:

30 hours of academic ground training covering aerodynamics (including stalls, upset recovery, and high-altitude operations), automation, adverse weather, transport airplane performance, leadership/CRM, and Part 117 fatigue
10 hours in a Level C or higher full flight simulator — at least 6 hours of which must be in a Level C or higher FFS representing a multiengine turbine airplane with a max takeoff weight of 40,000 pounds or more

CTP is your foundation. Examiners assume you understand swept-wing aerodynamics, Mach tuck, coffin corner, and stall recovery from the CTP curriculum. If you're fuzzy on those, fix it before the oral.

Aeronautical Experience: FAR 61.159

For an unrestricted ATP-Airplane Multiengine, FAR 61.159 requires 1,500 hours total time as a pilot, including:

Requirement	Hours
Total time	1,500
Cross-country	500
Night	100
Pilot in command (per 61.159(c))	250
Instrument	75 (actual or simulated)
Multiengine	50 (or 25 if mixed waiver applies)

Restricted ATP under FAR 61.160 reduces total time to 750, 1,000, or 1,250 hours depending on military experience or qualifying degree.

The ATP Practical Test: What the ACS Covers

The Airline Transport Pilot ACS (FAA-S-ACS-11) consolidates the ATP and Type Rating standards into one document. The eight Areas of Operation:

Preflight Preparation — certificates, weather, performance, operation of systems
Preflight Procedures — preflight inspection, flight deck management, engine start, taxi, before-takeoff checks
Takeoff and Departure Phase — normal, instrument, rejected, engine failure on takeoff
In-Flight Maneuvers — steep turns, stall prevention/recovery, recovery from unusual attitudes
Instrument Procedures — holding, precision/non-precision approaches, missed approach, circling, landing from a precision approach
Landings and Approaches to Landings — normal, with engine failure, no-flap/abnormal, rejected landing
Normal and Abnormal Procedures — systems failures, fire, smoke, evacuation, emergency descents
Postflight Procedures — after-landing, parking, securing

Tolerances are tight. Altitude during instrument maneuvers: ±100 feet. Heading: ±10°. Airspeed on approach: +10/−5 knots. Steep turns: ±100 ft, ±10°, ±10 kt, with bank ±5° of the 45° required bank. On a precision approach, you cannot exceed one dot of localizer or glideslope deflection.

What the ATP Oral Looks Like

The oral exam runs 2–4 hours for an ATP-only ride; longer when combined with an initial type rating. Expect deep questions on:

High-altitude aerodynamics — coffin corner, Mach buffet, swept-wing stall characteristics, low-speed buffet vs. high-speed buffet
Turbojet/turbofan performance — V-speeds (V1, VR, V2, Vref, Vapp), balanced field length, climb gradients, accelerate-stop and accelerate-go
Engine-out performance — second-segment climb gradient, driftdown, ETOPS basics
Icing — known icing definitions, certification, anti-ice vs. de-ice systems, supercooled large droplets
Weather — convective SIGMETs, PIREPs, microbursts, low-level wind shear, runway condition codes (TALPA)
Regulations — FAR 61.153, 61.155, 61.156, 61.158, 61.159, plus Part 91 IFR, Part 117 (if applicable), 8900.1 vol. 5
Aircraft systems — every system in the aircraft you're being tested in
Crew Resource Management — threat and error management, sterile flight deck, briefings, monitoring strategies

FAR 61.158 addresses use of an aviation training device or full flight simulator for the practical test — most ATP rides are conducted in a Level C/D FFS, which means your sim profile, switchology, and flow discipline are graded the entire time.

Common Bust Items

FAA data and DPE feedback consistently show the same bust areas:

Weight & balance / performance calculations that don't match the conditions briefed
Instrument approach briefings missing items the ACS now requires (NOTAMs, missed approach, minimums, terrain)
Engine failure on takeoff — late identification, wrong rudder, blowing through V2
Steep turns outside ±100 ft / ±10°
Stall recovery — pulling instead of reducing AOA, secondary stalls
Holding entries and timing busts in non-radar holds
Single-engine ILS — drift through localizer or busting glideslope while managing rudder trim

A Realistic 6-Week Study Plan

Week	Focus
1	ACS walkthrough, FAR 61.153–61.159, ATP-CTP review notes
2	Aircraft systems, limitations, memory items
3	Performance, W&B, takeoff/landing data, MEL philosophy
4	Weather, IFR procedures, approach briefings, holding
5	High-altitude aero, CRM/TEM, Part 117 (if 121-bound)
6	Mock orals, sim profile chair-flying, scenario drills

How GroundScholar Helps With This

GroundScholar runs an AI ATP examiner trained on the ATP ACS that adapts to how you answer. Stumble on Mach tuck and it will keep probing high-altitude aerodynamics until your answer is captain-grade. Nail crosswind landing performance and it moves on. Every regulatory cite is verified against the live FAR/AIM, so when the AI says "FAR 61.156 requires 30 hours of academic training," that's the current rule — not a hallucination.

The mock checkride runs the full ATP oral end-to-end, scores each ACS task, and gives you a pass-prediction with the specific Areas of Operation you're weakest in. Most users do 2–3 mocks before the real ride and walk in already familiar with the rhythm of the exam.

Ready to Pass on the First Attempt?

The ATP practical test rewards depth. Build it now, in the weeks before your sim slot, instead of trying to cram the night before. Drill the oral until your answers are short, confident, and cited.
