How to Teach Power-Off Stalls: The Approach Stall, From the Right Seat

A power-off stall is the approach stall — flown with idle power, full flaps, in a descending approach attitude, until the wing reaches its critical angle of attack and breaks. The maneuver rehearses the most lethal real-world stall scenario in general aviation: slow on final with the runway in sight. I’m Chris Palmer — two-time Master Aviation Educator, Gold Seal CFI, founder of Angle of Attack — and the first power-off stall lesson I taught as a fresh CFI was clean, ACS-aligned, and completely missed the point. Teach this maneuver as the scenario it represents and your student leaves with stall awareness that transfers to every landing they fly.

The CFI Toolkit Every New Instructor Wishes They Had on Day One

Most new CFIs build their teaching system from scratch — a binder of borrowed lesson plans, scattered notes, and ACS PDFs. The Anti-Binder Template is the one-page lesson framework I use to plan every lesson, including power-off stalls. Same scenario-first shape. Same Day-One focus.

Why Power-Off Stalls Are the Approach Stall — And Why They’re Lethal

The first power-off stall I taught was in Wisconsin in 2017. Fresh CFI ticket. My student climbed us to a comfortable practice altitude in a Cessna 172 and I briefed the maneuver the way I’d been briefed: clear the area, reduce power to idle, full flaps, hold the nose just above the horizon, let it slow, recover at the break, climb away. He flew three. The recoveries were clean. The headings held. The altitude loss was inside ACS tolerance. We came home and I logged it as a successful lesson.

It wasn’t. I’d taught him a maneuver. I hadn’t taught him an approach stall. He could have flown that practice-area exercise a hundred more times and still not been any more prepared for the situation that actually kills pilots in the pattern — slow on final, distracted, full flaps locked in, the airplane sliding into a stall the pilot doesn’t see coming.

That gap — between the maneuver the ACS measures and the scenario the airplane actually presents — is the entire reason this article exists.

The numbers carry the weight. Loss of control in flight is the leading cause of fatal general aviation accidents, and stall/spin is its primary mechanism. About half of LOC accidents happen in the traffic pattern, the regime we almost never practice in. The FAA’s foundational stall study, FAA-RD-77-26, found that distraction was the most common precursor to stall/spin accidents — pilots weren’t dying because they couldn’t recover, they were dying because they were looking at something else when the airplane got slow. That study became the backbone of AC 61-67C — Stall and Spin Awareness Training, the regulatory document every CFI should re-read before each new student.

After Colgan 3407 in February 2009 — a Q400 crew that pulled back on the stick during a stick-shaker warning and rode the airplane down — the FAA replaced the old 100-foot maximum altitude loss standard in the ATP PTS with a qualitative “minimal altitude loss appropriate to the airplane” standard. Pilots had been pulling back in stalls to save 100 feet. We’d accidentally trained them to do it. The same year, Air France 447 went down with the co-pilot holding the side-stick aft for three full minutes while the airplane stalled into the South Atlantic. In November 2015, the FAA published AC 120-109A — Stall Prevention and Recovery Training with one sentence at the center: “Reducing angle of attack is the most important pilot action in recovering from an impending or full stall.”

The student you teach today is the pilot who recognizes — or doesn’t — the same situation at 200 AGL on a real day with the runway in sight. Professionalism is not a certificate — it’s behavior. The behavior the FAA wants is the scenario, not the demonstration. (For the umbrella scenario-first method this article applies to one specific maneuver, see the parent article: How to Teach a Stall — A New CFI’s Guide.)

What Does the ACS Require for Power-Off Stalls?

Power-off stalls live inside three regulatory layers. Know all three before you teach your first one.

The CFR — the training-area-of-operation hook. Power-off stalls fall under 14 CFR 61.107(b)(1)(viii) “Slow flight and stalls” for Private Pilot training and 14 CFR 61.127(b)(1)(viii) “Slow flight and stalls” for Commercial. The CFR doesn’t specify the recovery point — that’s the ACS’s job. For CFI, the FAR hook is 14 CFR 61.183(i) — knowledge of “stall awareness, spin entry, spins, and spin recovery procedures.” The CFR establishes that the topic must be trained; the ACS prescribes how.

The ACS — three different standards, one CFI candidate. The 2017 ACS revision created a teaching distinction the SERP almost completely ignores. It’s load-bearing — burn it in:

• FAA-S-ACS-6 (Private Pilot ACS) — Area VII Task B: “Acknowledge cues of the impending stall and then recover promptly after a full stall has occurred.” The wing must actually break. The student must hold through the buffet.
• FAA-S-ACS-7 (Commercial Pilot ACS) — Area VII Task B: “Acknowledge the cues and recover promptly at the first indication of an impending stall (e.g., aircraft buffet, stall horn, etc.).” The student must NOT let the wing break. Buffet is the recovery cue.
• FAA-S-ACS-25 (Flight Instructor ACS, May 31, 2024) — Power-Off Stalls: the CFI applicant must demonstrate AND teach the maneuver from the right seat to both standards. The examiner role-plays as the student.

The skills the examiner measures stay constant across both ratings: heading ±10° in straight-ahead stalls, bank ±10° not to exceed 20° in turning stalls, and recovery completed no lower than 1,500 feet AGL for single-engine airplanes. Get to your practice altitude with that 1,500 AGL floor in mind — typical training-aircraft altitude loss in a clean recovery is 100-200 feet, with up to ~300 feet possible if AOA reduction lags. Start the entry high enough that the floor is never the constraint.

The handbooks — the why behind the standards. The Airplane Flying Handbook (FAA-H-8083-3C, October 2021) folded stalls into Chapter 5 — Maintaining Aircraft Control: Upset Prevention and Recovery Training — with the energy framework underneath in Chapter 4. The Aviation Instructor’s Handbook (FAA-H-8083-9B) Chapter 4 carries the teaching scaffolding for the brief, demo, manipulation, and practice phases. Read both. They’re free.

If you’re teaching a mixed-rating block — a private student and a commercial student in the same week — context-switch your coaching out loud. “For your rating, hold through the buffet. We’re going past the warning to the actual break.” Same lesson, different recovery point. (See the CFI checkride pillar guide for the broader Area VII context on your CFI ride.)

The Scenario-First Method Applied to Power-Off Stalls

The scenario-first method has five steps. They don’t change between stall types — only the scenario does. For power-off stalls, the scenario is the approach stall. Here’s how it maps.

Step 1: Pick the real-flight scenario the maneuver represents. Power-off stall = approach stall. You’re on final, configured for landing, the throttle is at idle, and the airplane is decelerating toward approach speed. Say it out loud at the start of the brief: “Today we’re going to fly the scenario of being too slow on final.”

Step 2: Brief the scenario, not the procedure. “Today we’re going to fly what happens when you slow too much on final. We’ll configure the airplane like we’re on a normal approach — full flaps, idle power, descending — and let the airplane get too slow on purpose, so you learn what the airplane tells you before the wing breaks.” Not: “Today we’re doing power-off stalls. Step 1, clear the area…”

Step 3: Demonstrate as if you’re flying the scenario in real life. Narrate what you’re seeing as if the runway were ahead of you. “We’re high on final. I’m reducing power to idle. Full flaps. I’m letting the airspeed bleed off. I’m watching the airspeed indicator — but more importantly I’m feeling the controls get mushy. Here comes the buffet — that’s the warning. Still holding back pressure — here comes the break. AOA first — release back pressure — wing’s flying again — adding power — leveling wings — back to climb.” The student watches a CFI fly the scenario, not perform a maneuver.

Step 4: Hand the controls. Coach the same scenario. “Your airplane. You’re on final. I’ll point at the airspeed if you’re getting slow. I won’t take the controls unless you ask. Fly the scenario.” The hardest part of Step 4 is keeping your hands off the yoke. The instinct is to grab. Calm as a skill — yours, first, before it’s theirs. Grab during a recovery the student would have flown and you’ve robbed the moment.

Step 5: Debrief the scenario, not the tolerances. “What did the airplane tell you before it broke? Could you feel the buffet? Did you have to think about the recovery sequence, or did it flow?” Not: “You lost 175 feet, the ACS allows 1,500 AGL recovery completion.” Tolerances are a checkride concern. The scenario is the lesson.

This is the scenario-first method I built into TotalCFI Lesson 3.4 — Scenario-Based Stall Training — power-off stalls are one of three single-maneuver focus blocks in that lesson, alongside power-on departure stalls and slow flight. The lesson takes a procedure-trained CFI candidate and turns them into a scenario-trained instructor. Be the CFI your student will trust on final.

How to Brief a Power-Off Stall Lesson (The 4-Part Brief)

The brief is where the lesson is won or lost. Four parts, five minutes, no PowerPoint.

1. Scenario. “Today we’re going to practice what happens when you slow too much on final. We’ll fly the scenario — full flaps, idle power, normal approach attitude — and let the airplane get slow on purpose, so you learn what the airplane tells you before the stall.”

2. Demo plan. “I’ll fly the scenario first. I’ll narrate what I’m watching — airspeed, attitude, the feel of the controls, the sound of the engine. When the stall breaks, I’ll recover with AOA first: release back pressure, roll wings level, add power smoothly, retract a notch of flaps. AOA before power. Always.“

3. Error correction expectation. “When you fly it, I’ll point at the airspeed if you’re getting slow before you’re ready. I’ll point at the attitude indicator if you’re pitching too aggressively. I won’t take the controls unless you ask. If I do take the controls, I’ll say ‘I have the airplane’ clearly. Otherwise the airplane is yours. We’re in sterile cockpit until you call recovery.”

4. Debrief expectation. “After we recover and the airplane is back at level flight and re-trimmed, I’m going to ask you to find the airport. That’s the distraction-based piece — recognition without fixation, the doctrine AC 61-67C is built around. Then on the ground we’ll debrief on what the airplane told you before the break, not on the altitude you lost.”

The brief is the contract. The Aviation Instructor’s Handbook calls this preparation. New CFIs almost always skip the brief or replace it with a procedure brief that lists steps. Don’t. See the CFI lesson plan template for the full lesson-plan shape this 4-part brief sits inside of.

How to Demonstrate a Power-Off Stall From the Right Seat

Demonstrating from the right seat is its own skill. Three things change when you slide across the cockpit.

Your sight picture is different. From the right seat the nose looks slightly different against the horizon — your reference points need recalibration before you teach. Spend a flight in the right seat before you have a student in the left seat. Fly slow flight, fly approaches, fly stalls solo or with another CFI. Map the right-seat sight picture to the same airplane attitudes you know cold from the left.

Your throttle hand is your left hand. In a side-by-side trainer the throttle is now on your left, the yoke on your right. The motor patterns are reversed. Reach for the yoke with your right hand and the throttle with your left until it feels automatic. If you’re flubbing the hand mechanics during the demo, you’re not teaching — you’re flying yourself.

Your rudder discipline matters more than ever. From the right seat, your right pedal is the same pedal mechanically, but you’re sitting offset. Coordinate carefully on the demo. If the ball isn’t centered when the wing breaks, you’ll get a wing drop — and that’s your fault, not the airplane’s. (More on the wing-drop thing in the 172-specifics section below.)

The narration is what makes this a teaching demo and not just a flight maneuver. Talk through every input. “Power coming back to idle. Carb heat on. First notch of flaps. Trimming for approach. Second notch. Third notch. Holding the sight picture. Airspeed bleeding through 65, 60, 55. Buffet — listen to it. Holding back pressure through the buffet. Break — and AOA first, release the back pressure — wing’s flying — power coming in smoothly, right rudder — wings level — first notch of flaps coming out — climbing away.” The student maps cues to a flight, not steps to a procedure.

The sterile-cockpit-on-entry rule is real and it matters. No non-essential conversation while the student is managing the airplane to the break. The cockpit is sterile. After recovery — once the airplane is back at level flight and re-trimmed — that’s when you introduce the distraction. “Now find the airport at our 2 o’clock.” That’s recognition-without-fixation, and it’s what AC 61-67C asks CFIs to build into stall training.

When do you take the controls? Rare. Only if the recovery is diverging — pitch wrong, power wrong, wings wrong, getting worse. Say “I have the airplane” clearly, fly the recovery, give it back when stable. If the recovery is rough but recovering — heading wandering, timing a beat slow — leave it alone and coach with one finger and three words. “Airspeed.” “Heading.” “Wings.”

The 5-Step Recovery Sequence (AC 120-109A Doctrine)

The recovery sequence below is adapted from the AC 120-109A template for GA single-engine power-off stalls. It is the regulatory bedrock and the most-cited paragraph in this article. Memorize the order. Teach the order. AOA reduction comes before power.

AC 120-109A, Change 1: “Reducing angle of attack is the most important pilot action in recovering from an impending or full stall.”

1. Reduce angle of attack. Release back pressure or apply forward pressure on the yoke until stall indications are eliminated. This is the first action. The wing must be flying before anything else matters. Pre-AC-120-109A doctrine taught “smoothly add power and pitch down” simultaneously — that’s what killed Colgan 3407 and AF447. The new doctrine separates the actions: AOA first, decisively, before any power input.

2. Roll wings level. If banked, use coordinated rudder and aileron back to wings-level — once the wing is unstalled. Do not roll a stalled wing. The ailerons can aggravate a wing drop on a wing that isn’t yet flying.

3. Add power smoothly to maximum allowable. Right rudder to neutralize left-turning tendencies. Don’t slam the throttle — smooth, deliberate. In a power-off (approach) stall, this is where progressive power restores climb capability.

4. Retract flaps incrementally. First notch comes out as soon as the descent is arrested and you’re climbing. Subsequent notches retract as airspeed builds. Don’t dump all the flaps at once — you’ll sink. In a real low-altitude approach stall, premature flap retraction is its own stall trap.

5. Return to desired flight path. Climb at Vx or Vy back to the entry altitude, or wings-level cruise as the scenario calls for. The recovery ends when the airplane is back on the desired flight path — not when the wing is unstalled.

Recovery completed no lower than 1,500 feet AGL for single-engine airplanes per the Private and Commercial ACS. Typical training-aircraft altitude loss in a clean recovery: 100-200 feet. If altitude loss exceeds ~300 feet, the recovery was slow — back to the brief on AOA reduction.

The reason this order matters is the reason AC 120-109A exists at all. After Colgan 3407 the FAA pulled the “minimum altitude loss” recovery standard from the ATP PTS in 2012 because pilots were prioritizing altitude over AOA reduction — and dying for it. The 2014 publication of AC 120-109A (with Change 1 in 2015) codified “reduce AOA first” as the universal stall recovery principle for Part 121 with a strong recommendation for Part 91, Part 135, pilot schools, and training centers. We are training centers. We teach the AC.

The 5 Most Common Student Errors on Power-Off Stalls

Errors aren’t problems to fix. They’re data. Each of these reveals a specific gap in the student’s stall understanding — and gives you the material for the next demo.

1. Releases back pressure at the buffet, not at the break (Private student). The buffet is the warning; the break is where Private recovery starts. The student is reacting to the warning, not the stall. Coach: “Buffet is the warning. For your rating, you need to feel the break. Hold the back pressure through the buffet.” Demo: hold through the buffet to the actual break — narrate the buffet-to-break transition. Debrief: “What scared you about going past the buffet?” (Note: at Commercial, recovering at the buffet is the standard — context-switch the coaching to match the rating.)

2. Adds power before reducing AOA. Pre-AC-120-109A doctrine — the student learned “add power and pitch down” simultaneously. They’re sequencing the recovery wrong, and in a real low-altitude approach stall this is the failure mode that kills people. Coach: “AOA first, power second. The wing has to be flying before the power matters. Release back pressure. Now add power.” Demo: a recovery with deliberate AOA reduction first, hold the unstalled wing for a beat, then progressive power. Debrief: “Walk me through the sequence. What’s the first thing you do?”

3. Doesn’t set up the approach configuration cleanly. Sloppy setup — the student dives into the maneuver without trimming for approach speed, without verifying flaps fully extended, without ensuring power is actually at idle. The scenario isn’t real because the setup isn’t real. Coach: “We’re flying a real approach. Trim for approach speed. Flaps full. Power idle. Hold the sight picture. Now slow it down.” Demo: a deliberate setup, every step verbalized, scenario language throughout. Debrief: “What’s different between this approach setup and a normal landing setup?”

4. Loses heading or altitude during recovery. Task saturation — the student is processing the recovery so hard they’ve stopped flying the airplane. Heading drifts, the recovery starts spiraling. Coach: “Recovery is flying. Hold the heading with rudder. Look outside. Let the wing fly.” Demo: a recovery with the heading bug visible — show how rudder holds heading while pitch handles AOA. Debrief: “What were you watching during the recovery — inside or outside?”

5. Fixates on altitude loss instead of AOA reduction. Old doctrine creeping in — the student (or worse, the CFI) is thinking minimize altitude loss instead of reduce AOA. This is the failure mode AC 120-109A was written to prevent. Coach: “Altitude loss is a checkride number. AOA reduction is what saves you. If you have to lose 200 feet to get the wing flying again, lose the 200 feet.” Demo: nothing in the airplane — back to the briefing room to re-anchor the doctrine. Debrief: “If you couldn’t reduce AOA without losing altitude, would you sacrifice the altitude or the wing?”

The pattern across all five: the student is processing a procedure when they should be reading the airplane.

Buffet vs. Break: Why Private and Commercial Students Recover at Different Points

The 2017 ACS revision split the recovery point between Private and Commercial standards. Most CFI candidates teach a single recovery point and don’t realize the standard inverts at the next rating. Burn this table in.

Standard	Recovery Point	ACS Citation	What You Teach the Student
Private Pilot (FAA-S-ACS-6)	After full stall break — wing must actually stall	Area VII Task B Skills: "Acknowledge cues of the impending stall and then recover promptly after a full stall has occurred"	Hold through the buffet. Feel the break. Then recover. AOA first.
Commercial Pilot (FAA-S-ACS-7)	At first indication of impending stall	Area VII Task B: "Acknowledge the cues and recover promptly at the first indication of an impending stall (e.g., aircraft buffet, stall horn, etc.)"	Buffet is your recovery cue. Don't ride it through to the break. Crisp recovery.
CFI (FAA-S-ACS-25)	Demonstrate AND teach both standards from the right seat	Power-Off Stalls Task: CFI applicant must demonstrate instructional proficiency on Private and Commercial standards	Teach the rating your student is pursuing. Demonstrate both on your CFI checkride.

The change was driven by post-Colgan/AF447 doctrine refinement — Commercial pilots, expected to operate in higher-performance contexts, recover earlier so the wing never breaks. Private pilots train past the warning to the actual break because that’s where the real-world stall lives in primary training. The CFI’s job is to teach to the rating in the seat next to them and demonstrate both on the CFI ride.

If you’re examining what kind of CFI you want to be — the one who teaches the procedure or the one who teaches the airplane — this distinction is one of the cleanest places to draw the line. A CFI who teaches “stall recovery” without naming which recovery point is whose standard is teaching the maneuver, not the standard. (For the broader CFI checkride context including how examiners role-play students for stall tasks, see the CFI checkride pillar guide.)

Cessna 172 Power-Off Stall Specifics (And What Not to Expect)

The Cessna 172 is the most-stalled training airplane in the country. Know how it behaves cleanly so you can teach what’s normal — and what isn’t.

A coordinated power-off stall in a 172 typically breaks at roughly 40-48 KIAS depending on weight, configuration, and CG. The stall warning horn activates 5-10 KIAS above the actual break. The break itself is mild — clean nose drop, minimal roll, the airplane recovers willingly when AOA is reduced.

What the 172 does NOT typically do on a power-off stall: drop a wing. The prominent left-wing drop is a power-on characteristic, driven by propeller slipstream asymmetry, P-factor, and torque reaction at high power. With the throttle at idle and the wing slowing in coordinated, controlled flight, the 172 stalls cleanly. If a wing drops on your power-off entry, the ball wasn’t centered — and that’s a teaching moment about rudder discipline, not an expected characteristic of the airplane. Don’t brief your student to “expect a left wing drop on a power-off stall.” That’s a power-on lesson (see the sister article: How to Teach Power-On Stalls).

The POH (Section 4 — Normal Procedures, Section 5 — Performance) is your single source of truth for the airplane’s specific stall speeds and recovery technique. Read your specific airplane’s POH before each new student in case there are model-year differences. The doctrine is universal; the numbers are airplane-specific.

A note on the prerequisite: a student who doesn’t own slow flight has no business flying stalls. If your student is fighting the airspeed indicator at minimum controllable airspeed, they will fight it harder at the break. Get slow flight rock-solid first. (See the slow flight teaching playbook for the precursor lesson.)

How Long Should a Power-Off Stall Lesson Last?

Power-off stalls are a sub-lesson, not a full flight on their own. A first-time scenario-first power-off stall block is about 1.5 hours of total syllabus time.

• Ground brief: 15-20 minutes. Scenario, AC 120-109A doctrine, the ACS standard for the rating in the left seat, the 4-part brief. End with: “What does the airplane do before it stalls?”
• Flight: 0.6-0.9 hours. Climb to safe altitude (high enough to honor the 1,500 AGL recovery floor with margin). Demo the approach-stall scenario. Hand off, coach. Reset. Three good handoffs beat eight rushed ones. Pair with slow flight on the same flight if the student needs the prerequisite reinforcement.
• Debrief: 15-20 minutes. What did the airplane tell you before, during, and after the break. Then the error patterns. Then the next lesson plan.

Don’t fly the same stall lesson twice in a row. Let it breathe. Come back two flights later with a different scenario — power-on departure stalls (F2), or accelerated stalls in the steep-turn block. The student needs time to integrate. Your certificate is your license to learn — and so is theirs.

---

What Are Students Actually Learning When You Teach This Well?

When you teach a power-off stall well, four things happen at once — and only one of them is “they can recover from a power-off stall.”

AOA discipline. The durable lesson. Airspeed is incidental, AOA is causal. They carry that into every approach and go-around for the rest of their flying life.

Approach-energy awareness. What slow on final feels like, sounds like, looks like — before the buffet, at the buffet, at the break. The safety lesson. They feel the airplane getting slow before the airplane has to tell them.

Recognition without fixation. They learn to find the airport while the airplane is recovering. The airmanship lesson. AC 61-67C has been asking us to teach this since the 1970s.

Calm-as-skill. They watch you fly a stall, talk through it, correct a slightly-off recovery without snapping. They take that voice with them.

The deepest version is what I call Restorative Airmanship — teaching a pilot to fly in a way that restores their relationship with the airplane every time it’s threatened by stress, procedure, distraction, or fear. The CFI who teaches the scenario sends a pilot home with airmanship. The CFI who teaches the maneuver sends them home with a checkride trick.

Once a student is recognizing the buffet, holding through to the break, and recovering AOA-first cleanly, the conversation about spins is the next one to have. That’s your bridge to the CFI spin endorsement guide. And the departure-stall scenario completes the picture: the power-on stall teaching playbook is the natural sister lesson.
