ACS Maneuver Standards: Every Private Pilot Tolerance (2026)

ACS maneuver standards: every tolerance a private pilot applicant must hit

The Airman Certification Standards publish an exact numeric tolerance for nearly every maneuver on the private pilot checkride — and several of those tolerances are deliberately asymmetric. Here is every one we could verify directly against FAA-S-ACS-6C, cited by task code, in one place you can check before you fly.

Key takeaways

Every tolerance below is cited to a specific FAA-S-ACS-6C task code (Private Pilot — Airplane). If a task is not listed here, treat it as unverified rather than assume the general ±10 kt / ±100 ft standard applies unchanged.

Several ACS tolerances are asymmetric on purpose: short-field landing touchdown is +200/-0 feet (long is acceptable, short is not), and slow flight airspeed is +10/-0 knots (fast is acceptable, slow risks a stall).

The default cruise-flight tolerance across most maneuvering tasks is altitude ±100 feet, heading ±10°, airspeed ±10 knots — but task-specific tolerances override this default where the ACS publishes one.

Stalls do not carry a published numeric altitude-loss tolerance in the Private Pilot ACS. The standard is qualitative: recognize the first indication and recover promptly, minimizing altitude loss.

Soft-field takeoff and landing tasks are evaluated on technique (ground-effect acceleration, no side drift, minimum float), not a published touchdown-distance tolerance — do not memorize a number that does not exist.

Why the tolerance is the test

A DPE is not grading whether you can fly the maneuver in some general sense. The Airman Certification Standards define a specific, numeric window for each task, and staying inside it — or not — is the entire basis for a satisfactory or unsatisfactory score. FAA-S-ACS-6C is the current standard for the private pilot airplane certificate, and it is free at faa.gov.

The tolerances below are organized by task code exactly as the ACS lists them, so you can look up the maneuver you are about to fly and know the number you are being held to before you take the runway. Where the ACS publishes an asymmetric tolerance — allowing more room on one side of the target than the other — it is stated here exactly as asymmetric. Symmetrizing a published asymmetric tolerance (rounding +200/-0 into "±100", for example) teaches the wrong risk model, because the two directions of error are not equally dangerous.

Steep turns — PA.V.A

The steep turns task evaluates coordinated control at a bank angle steeper than normal maneuvering flight.

Bank: 45°, ±5°
Altitude: ±100 feet
Airspeed: ±10 knots
Rollout heading: ±10° of the entry heading

The bank tolerance is the one applicants underestimate. Five degrees either side of 45° is a narrower window than it sounds once you are actively managing altitude and back-pressure through 180° of turn — it rewards a disciplined instrument scan, not just a good sight picture over the cowling.

Slow flight — PA.VII.A

Slow flight is evaluated at a specified airspeed at which any further increase in angle of attack, or reduction in airspeed, would result in a stall warning.

Airspeed: +10/-0 knots of the specified speed
Altitude: ±100 feet
Heading: ±10° (straight flight) or bank ±10° (turning flight)

The airspeed tolerance is asymmetric for a specific safety reason: the target speed already sits just above the stall warning. Flying faster than the target is a technique deviation. Flying slower risks the exact condition — an unplanned stall — that the maneuver exists to teach you to recognize and avoid.

Power-off and power-on stalls — PA.VIII.B / PA.VIII.C

Both stall tasks are scored on recognition and recovery technique, not on a numeric altitude-loss tolerance — the Private Pilot ACS does not publish a maximum feet-lost figure for these tasks.

Recognizes and recovers promptly at the first indication of a stall (buffet, stall horn, or aerodynamic cue)
Recovers with minimum loss of altitude appropriate to the aircraft
Heading: ±10° during straight-ahead entries; bank: ±10° during turning entries

Do not memorize an altitude-loss number for stalls — there is not one to memorize. The examiner is watching for the moment you recognize the stall and the control inputs you make in the next two seconds, not counting feet against a published limit.

Short-field takeoff and landing — PA.IV.A / PA.IV.E

Short-field tasks are where the ACS is most explicitly asymmetric, because the two tasks are solving for opposite risks: clearing an obstacle on takeoff, and stopping within a limited surface on landing.

Short-field takeoff and climb (PA.IV.A): airspeed +10/-5 knots of the recommended speed until clear of the obstacle
Short-field approach and landing (PA.IV.E): airspeed +10/-5 knots of the recommended approach speed on short final
Touchdown point (PA.IV.E): at or within 200 feet beyond a specified point (+200/-0) — touching down before the point does not satisfy the task

The touchdown tolerance only allows error in one direction. A long landing within 200 feet is inside standard; a landing short of the specified point is not, because the entire premise of the task is respecting a limited landing surface. There is no symmetric "±100 feet" version of this standard — do not fly it as if there were one.

Soft-field takeoff and landing — PA.IV.B / PA.IV.C

Soft-field tasks are evaluated on technique, not on a published distance tolerance. There is no touchdown-point or ground-roll figure to hit — the maneuver instead requires:

Lifting off at minimum safe airspeed and remaining in ground effect to accelerate to a safe climb speed (takeoff)
Touching down with no side drift, minimum float, and at minimum safe airspeed (landing)
Maintaining directional control throughout the soft, uneven, or rough surface roll

If a study source hands you a touchdown-distance number for soft-field, treat it skeptically — the published standard for this task is qualitative, and no such distance appears in FAA-S-ACS-6C.

Traffic pattern operations — PA.III.A

The traffic pattern task carries the general maneuvering tolerance rather than a task-specific one:

Altitude: ±100 feet
Airspeed: ±10 knots

The difficulty in this task is rarely the tolerance itself — it is holding it while also flying a rectangular ground track, watching for traffic, and managing a descending configuration change on every leg.

Cross-country navigation — PA.VI.A / PA.VI.B

Pilotage (PA.VI.A) and dead reckoning (PA.VI.B) are evaluated together against how well the planned navigation log survives contact with the actual flight:

Navigates by pilotage using landmarks, and by dead reckoning using pre-computed headings, groundspeeds, and elapsed times
Arrives at checkpoints within 3 minutes of the initial or revised estimated time en route (ETE)

The 3-minute checkpoint window is the number applicants forget to plan for, because it is scored against your own flight log, not against some external clock. A wind correction that is off by a few degrees compounds silently over a 30-mile leg until the checkpoint arrives late enough to fail the tolerance.

The stabilized approach, across every landing task

"Stabilized approach" is not a separate ACS task code for the private pilot certificate — it is the descriptor that runs through every approach-and-landing task (normal, short-field, soft-field). In practice, it means arriving at the specified airspeed tolerance for that task on a consistent, unhurried glide path, rather than making large power or pitch corrections in the final seconds before the flare.

The airspeed tolerance for the approach you are flying is set by the task itself — short-field is +10/-5 knots, as above. A stabilized approach is what lets you actually hold that number through the flare instead of discovering it was gone the moment you round out.

Frequently asked questions

What happens if I bust a tolerance once during the checkride?

A single momentary deviation that you recognize and correct is generally treated differently than a sustained deviation outside the tolerance — the ACS standard language for most tasks describes maintaining the parameter, not achieving it once. Ask your instructor how your specific DPE has historically scored borderline calls; this varies by examiner within the bounds of the written standard.

Are these tolerances the same for Part 141 schools?

Yes. The Airman Certification Standards are the FAA-published standard for the certificate itself, and they apply regardless of whether your training was conducted under Part 61 or Part 141. A 141 training course outline may sequence the maneuvers differently, but the checkride tolerance does not change.

Why is the slow flight airspeed tolerance +10/-0 instead of ±10?

Because the target airspeed in slow flight already sits just above a stall warning. The ACS allows you to fly a bit faster than the target without penalty, since that is a minor technique deviation — but not slower, since slower is the direction that risks the exact stall the maneuver is designed to have you recognize and avoid.

Is there a maximum altitude loss allowed during a stall recovery?

Not as a published number in FAA-S-ACS-6C. The standard is qualitative: recognize the first indication of the stall and recover promptly, with minimum altitude loss appropriate to the aircraft. Do not memorize a specific feet-lost figure for this task — none is published.

Does the short-field landing tolerance let me land long?

Yes, within limits — the published tolerance is touchdown at or within 200 feet beyond the specified point, which is why it is written +200/-0. A long landing inside that 200-foot window is inside standard. Touching down before the specified point does not satisfy the task, because the maneuver is built around respecting a limited landing surface.

Where can I read FAA-S-ACS-6C myself?

It is published free by the FAA at faa.gov as a PDF, under Airman Certification Standards for the private pilot airplane certificate. Reading the task list directly is worth doing at least once — this page summarizes the numeric tolerances, but the ACS also lists the specific knowledge and risk-management elements tied to each task.

Do these tolerances apply to a home flight simulator too?

The tolerances themselves are the same published standard regardless of what you are flying — a bank angle of 50° is 5° outside the steep-turn standard whether you are in a Cessna 172 or a desktop simulator. What does not carry over is loggability: time practicing against these tolerances on a home simulator is never loggable toward your certificate (14 CFR 61.51), even though rehearsing the numbers is genuinely useful preparation.

Do these tolerances change for the commercial or CFI certificate?

Yes — each certificate has its own ACS or PTS document with tighter tolerances for most tasks. This page covers FAA-S-ACS-6C for the private pilot airplane certificate only; do not carry these numbers forward to a commercial checkride without checking the applicable commercial ACS.
